Title: Comparing HDDs - strange results Post by Christer on Mar 4th, 2004 at 5:22pm
Hello all!
I have two HDDs, a new 120 GB Hitachi 7K250 with 8MB cache and a three years old 40 GB IBM 60GXP with 2 MB cache. The 7K250 is Primary Master and the 60GXP is Primary Slave. The rearmost partition on both (16-18GB) are FAT32, dedicated to Ghost Images. I have the same Images on both HDDs, created to the target partition on the 60GXP and copied to the 7K250. When I do integrity checks, the "transfer rates" are bothering me. The latest Image, which is approximately in the middle of both partitions (8-9 GB from the end of both HDDs), is checked at 142 MB/min on the 7K250 compared to 397 MB/min on the 60GXP. I promptly did a benchmark in AIDA32 with the following results: Quick Linear Read - 7K250 = 58.3-28.1 MB/s (46.8 avg) QLR - 60GXP = 38.8-18.5 MB/s (31.2 avg) Random Read - 7K250 = 57.6-27.9 MB/s (46.0 avg) RR - 60GXP = 35.2-17.8 MB/s (30.7 avg) Buffered Read - 7K250 = max 73.9 MB/s (73.7 avg) BR - 60GXP = max 74.4 MB/s (74.2 avg) (min readings omitted, low dips due to unknown interference) Average Access - 7K250 = 11.8-13.4 ms (12.6 avg) AA - 60GXP = 12.2-13.8 ms (13.0 avg) The 7K250 should outperform the 60GXP and it does in the AIDA32 benchmark but why the very low performance when running the integity check in Ghost? I would expect Ghost to create an Image quicker to a different HDD than to a different partition on the same HDD and that goes for restoring too but not for integrity checks which are read only operations. Ideas anyone? Thanks for Your time, Christer |

I have an image stored at the slow end of an 80-gig drive that is several years old. To be honest, I don't recall who made this drive. I think it's an IBM 120-GXP, but I can't tell from the device mgr. But I bought it when 80-gig drives were the ones to get. The drive has 3 partitions: 12+34+34.
Just checked the image & Ghost reports between 500 & 600-MB per min. So your 60GXP number seems reasonable. The only problem is the low check speed of the master. I suspect the image may have become fragmented while transferring. I wouldn't defrag it, but check its level of fragmentation to see what you're getting. A fragmented image would slow down the read speed. I had a similar problem once. (I've had just about every problem :'( ) Since your benches are good, there should be nothing physicaly wrong with the drive. I use Diskeeper for frag checks. They have a demo if you need. http://www.executive.com/diskeeper/diskeeper.asp Ghost reboots into DOS, so I don't think the OS matters. I'm using a 2.2-GHz P4 CPU, which will affect the speed of the check. What CPU do you have? It's not an SATA drive, is it? |

Hello guys,
thanks for Your replies! El Pescador, Quote:
The Secondary Master is a CD/R-RW running at PIO4 and the Secondary Slave is a DVD-ROM running at ATA33. Quote:
The OS is WinXP pro but since Ghost runs from DOS, I agree with Radministrator that it shouldn´t matter. BIOS settings are checked and in XP's device manager both drives run in UDMA mode 5, which is verified by the benchmark. I doubt that it would matter because the rates are way below PIO4 which is 16.7 MB/s. The rate of the 7K250 is some 2-3 MB/s but the 60GXP stands out at 6-7 MB/s ...... :-/ ...... ! Radministrator, Quote:
First, I actually created each Image twice, one to each HDD. The create speed was also much lower on the 7K250 but I thought that might be due to reading from and writing to different partitions on the same HDD. I have not yet restored from either of the HDDs. The resulting check speed on the master was the same low rate as when checking the copied Images. Regarding defragmentation, all Images are split in 650 MB chunks if I in the future should want to burn to CDs. When Ghost creates the Images, it leaves a small slack between each span. These small spaces are actually written to during the next creation, resulting in the second, third and so on, Images becoming fragmented. I had a fragmentation level of ~30% but if 6 out of 19 large files become fragmented, thats the percentage. I know that Images shouldn´t be defragmented but copying the files also defragments. I decided to reformat the 60GXP partition and copy the files, one by one, from the 7K250 to it. All copied Images passed the integrity check and not a single file is fragmented. Next, I reformated the 7K250 partition and copied the files, one by one from the 60GXP to it with the same results from the integrity check and fragmentation level. Quote:
I used to use Norton Speed Disk but I have come to the conclusion that it fights the XP "on the move" defragmentation and relocation of files. Speed Disk has one idea of what is the optimum and as soon as XP regains control, it starts moving things around to suit its preferences. It actually feels like, after running Speed Disk, the computer slows down a wee bit but after a few restarts it picks up normal speed again. My reaction to this is to quit using Speed Disk and let the native XP tool handle it. I use the "Analysis" funtion of Speed Disk, though, for a second opinion on fragmentation levels. Quote:

2 things:
1. i don't think it's a good idea to mix dma & non-dma devices on the same chanel. i think this forces ALL devices to run in pio mode. i think different DMA devices can run at diff DMA speeds, such as 1 at DMA33 & another at DMA100 on the same controller, but once you put a pio device, i think ALL devices on that channel must run at/in pio mode. i could be wrong, tho. 2. there are different ways to measure fragmentation. suppose a partition contains 10 files, and 1 of them is fragmented into 2 parts. that would be reported as 10% fragmentation. but suppose that same file is broken into 100 parts or 1000 parts, or a million. technically, the partition would STILL be reported as 10% fragmentation (only 1 file in 10). but this would be a much worse fragmentation that the previous example mentioned. so you have to delve deeper into exactly how bad the files are bfragmented. |
Title: Re: Comparing HDDs - strange results Post by Christer on Mar 5th, 2004 at 8:18am Quote:
That´s a different issue regarding the performance of the opticals which share the Secondary. The HDDs share the Primary and are both ATA100. I have experimented a bit with the setup of the hardware and mixed as follows: Primary Master - 60GXP - ATA100 Primary Slave - CD-R/RW - PIO4 (MultiWord 2) Secondary Master - empty front mounted rack in waiting for delivery of new HDD Secondary Slave - DVD-ROM - ATA33 I did an AIDA32 benchmark of the 60GXP. The results were the same as when the 60GXP was alone on Primary. (I saved and still have the results for Linear Read and Buffered Read, with and without the CD-R/RW as Primary Slave. If You or anyone else want to see them, just holler!) In the early days of IDE, the controller set itself to the lowest transfer rate of any device connected to it. In recent years they came up with Independent Device Timing which means that when the respective device takes its turn on the channel, it transfers at its own rate. My motherboard is three years old and obviously supports IDT. Quote:
Yes and that´s why I use Speed Disk for a "second opinion". When there is fragmentation they (XP and SD) always differ in the percentage but now, for my two partitions holding Ghost Images, they agree that the fragmentation level is 0%, the number of fragments per file is 1.00 and the number of "additional file parts" (or whatever it's called in english?) are 0. I´m 99.99% certain that the files are not fragmented. Christer |
Title: Re: Comparing HDDs - strange results Post by Radministrator on Mar 5th, 2004 at 11:27am
i am tired, so maybe i'm missing something. however u say "The HDDs share the Primary and are both ATA100", but show the pio4 cd sharing the primary channel.
are u sure Independent Device Timing pertains to pio with dma, and not just different levels of dma? (i.e. 33, 66, 100, 133) okay, i think you ruled out fragmentation, altho, if that image is not vital, i would be interested to see what happened following a defrag of that drive. so we still don't know why the low check speed on the new 120-gigger, right? |
Title: Re: Comparing HDDs - strange results Post by Ian Dunster on Mar 5th, 2004 at 12:47pm
Hi Christer.
The 7K250 should outperform the 60GXP and it does in the AIDA32 benchmark but why the very low performance when running the integity check in Ghost? This may shed some light: http://linux.tu-varna.acad.bg/~lig/freedos/ I don't think Ghost has a DMA controller - If not, then it will be operating in PIO mode. Ian. 8) |

Ghost can use DMA. Have a look at your 'Ghost Diagnostic Error File' and see if it is using DMA. http://service1.symantec.com/SUPPORT/ghost.nsf/pfdocs/1999021911433525 Ian. 8) |

I have "defragmented" the Image partition on the 7K250. No defragmentation took place and the time to do the integrity checks are the same.
I noticed that the cluster sizes differ with 32kB on the 7K250 and 16kB on the 60GXP but that shouldn´t make such a difference ...... ??? ...... or should it? Christer |
Title: Re: Comparing HDDs - strange results Post by rocknroll on Mar 8th, 2004 at 3:13am
Does it make any difference what order you run the integrity checks? Like is the second one faster than the first, or is the 7K250 always slower?

Title: Re: Comparing HDDs - strange results Post by Pelson on Mar 8th, 2004 at 3:25am
all things being equal, i would expect the drive with 32kb clusters to go faster than the one with 16kb clusters.
since you have both hard drives on the same controller, the pio-dma issue is not relevant because that only pertains to drives/devices on the same controller (primary, secondary). |

I have six different Images created at different points of the install procedure. Each one is 2.5-3 times slower to check on the 7K250, no matter which gets checked first. I have created an additional Image of the system to each of them, as the system is at present time. I checked the Images and also restored using each Image and the one on the 7K250 is 2.5-3 times slower in all operations. Quote:
I would expect that too but it is the opposite! I had a thought which pertains to the setup of the drives respective firmware. I´ve heard about "normal seek mode" and "quiet seek mode" where the latter should yield lower performance. The AIDA32 benchmarks doesn´t indicate any difference so, I buried that thought. Christer |

In the end the most important thing is the reliability of your images. Speed comes in a destant second. Altho I too wonder why the difference.

Title: Re: Comparing HDDs - strange results Post by Christer on Mar 8th, 2004 at 7:17am
Hi Crawdaddy!
I´m with You all the way on that one but 2.5 -3 times slower is too much to swallow without trying to find out why. I just did an Integrity Check on an Image on the 7K250 with the 60GXP powered off in the rack in order to rule out any possibility of interference. Still slow as molasses! One observation that I have failed to mention is that the time ticks down second by second when the 60GXP is at work but when the 7K250 is at work, it can pause for several seconds (5-10) and then it catches up. I think that all of this compounds into a very strange behaviour! Christer |

Hi Christer.
One observation that I have failed to mention is that the time ticks down second by second when the 60GXP is at work but when the 7K250 is at work, it can pause for several seconds (5-10) and then it catches up. That sounds like something to do with the cache on the 7K250. There is a diagnostic program from Hitachi that you could run here: http://www.hgst.com/hdd/support/download.htm and the user manual is here: http://www.hgst.com/downloads/dft32_user-guide.pdf Their main support home page is here: http://www.hgst.com/portal/site/hgst/?epi_menuItemID=a401d71a474b26fe25ad4e8060e4f0a0&epi_menuID=e41fff51ec9a8f8d5f5a530560e4f0a0&epi_baseMenuID=22f0deefa8f3967dafa0466460e4f0a0 Try the diagnostic and see if it comes up with anything.

Hi again Christer!
Update: The drive may not have been sut-up INTERNALLY to operate DMA, or at ATA100/133, and may actually be operating WITHOUT DMA, or at ATA66 - See below: Feature Tool (v1.92) The Feature Tool allows you to control some of the features of our Deskstar and Travelstar high performance ATA hard disk drives and supports 48-bit addressing, so it will work with the new large capacity drives. This version adds support for our latest drives. The Feature Tool allows you to: Enable or disable the read-ahead or write cache. - THIS MIGHT BE DISABLED - IAN Change the drive Automatic Acoustic Management settings to the: Lowest acoustic emanation setting (Quiet Seek Mode), or Maximum performance level (Normal Seek Mode). Change the predefined capacity of the drive. This option can be used in situations where there is a BIOS limitation and the drive is not recognized. See the Users Guide for specific details. Switch the Ultra DMA mode - THIS MIGHT BE INCORRECTLY SET - IAN Change Advanced Power Mode - allows you to change between the lowest power consumption and the highest power consumption (maximum performance level). Show Drive Temperature - shows the current drive temperature in Celsius and Farenheit. My SeaGate drive also has a utility for changing the INTERNAL settings, but I didn't need to change any as they were already correct. - some BIOS's and older PC's cannot use ATA100/33, so when ATA100/133 drives first came out, the drives were set INTERNALLY to ATA66 by default to maintain compatibility - the user had to manually change them to ATA100 mode. I think the 'Enable or disable the read-ahead or write cache' setting might be your problem - it should be ENABLED. Let us know what happens! Ian 8) |

Hi Ian!
I´ve been busy this afternoon but not with anything that I´m paid for ...... :-X ...... ! When I prepared to install the new HDD, I ran IBM DFT on both the 60GXP and the 7K250. They both came out "green". Afterwards I did an "Erase Disk" on the 60GXP and finally updated the firmware on it. Now, there was a new version of IBM DFT which I downloaded an ran with the same results. Quote:
I´ve been playing with thoughts along those lines too but the AIDA32 benchmarks indicate that it is operating in "Ultra DMA Mode 5" = ATA100. If not, the Buffered Read would not go above 66 MB/s. About "Quick Seek Mode" and "Normal Seek Mode", I think that the AIDA32 benchmarks on Average Access indicate that it is operating in "Normal". I downloaded the Feature Tool too and will run it later just to confirm what I think I know or to find the problem. By the way, I have created and used all flavours of Ghost Boot Disks, using MS-DOS and PC-DOS as well with the same results. I checked the opticals and the CD-R/RW operating in "Multi-Word DMA Mode 2" = PIO4, checks an Image at 101-103 MB/s. The DVD-ROM operating in "Ultra DMA Mode 2" = ATA33, checks an Image at 106-108 MB/s. It seems to me like Ghost misidentifies the 7K250 ...... ??? ...... In IBM DFT, the 60GXP is said to be DMA Mode 5 where as the 7K250 is said to be DMA Mode 6 (or words which I don´t remember exactly, to that meaning). According to the WinXP Device Manager, the mentioned devices operate in the mode within "double quotes". I´ll be back ...... >:( ...... ! Christer |
Title: Re: Comparing HDDs - strange results Post by Christer on Mar 8th, 2004 at 1:29pm
I´ve had a look in the Feature Tool and both HDDs were identically configured:
SMART status = GOOD UDMA mode = ATA100 Accoustic management = Disabled (which I understand as giving the best performance) Power management = Disabled (which I understand as giving the best performance) Write cache = Enabled Read look-ahead = Enabled If I have understood this correctly, the HDDs are properly configured and the problem isn´t with the 7K250. My belief that it is a case of mistaken identity is strenghtened. Christer |

'the 7K250 is said to be DMA Mode 6 (or words which I don´t remember exactly, to that meaning). '
UDMA Mode 6 is ATA133 UDMA Mode 5 is ATA100 try changing it to UDMA 5/ATA100 (or conversely, change it to UDMA 6/ATA 133) If you have one setting as ATA100 and are trying to use UDMA 6 then it's possible that could be the trouble - DOS, i.e. the Ghost environment, is very unfriendly at the system level - if it doesn't like something it may not even tell you why!

Running the Drive Fitness Test, the 7K250 is said to have "ATA Compliance = ATA-6" whereas the 60GXP is said to have "ATA Compliance = ATA-5".
Running the Feature Tool, they are both said to have "Max UDMA Mode = 5" and it is possible to set them to Mode 0-5. Both were/are set to Mode 5. If Hitachi has problems detecting what the 7K250 is, then there is the possibility that I´m right about Ghost mistaking the identity and performance.

Have a look at the web pages below, discussing transfer rates and compare to what I get from my devices:
http://www.storagereview.com/guide2000/ref/hdd/if/ide/modesUDMA.html and http://www.storagereview.com/guide2000/ref/hdd/if/ide/modesDMA.html All my devices transfer at rates below Ultra DMA Mode 0 which is 16.7 MB/s.

Try putting the two HDD's on different controllers, and then see if that makes a difference - The drive set as MASTER may be hogging the bus - try this:
Primary Master - 7K250 Primary Slave - DVD-ROM Secondary Master CD-R/RW Secondary Slave - 60GXP Ian. 8) |
Title: Re: Comparing HDDs - strange results Post by Christer on Mar 8th, 2004 at 7:16pm
All the devices are jumpered to Cable Select but I don´t think that it would make any difference if jumpered Master and Slave respectively.
When I bought and installed the mobile rack, the only option that worked was to use CS. Any other jumping and the computer didn´t boot, it didn´t detect the PM. Since I have the 60GXP in the mobile rack, I have tried powering it off, leaving the 7K250 alone on the Primary but no change in behaviour. Christer |

This sounds suspicious! Do you have a proper Ultra ATA-capable 40 pin, 80 conductor cable with the blue (system board), black (master) and gray (slave) connectors? - if you are using a 'normal' (an all gray) ATA cable, then it won't work in ATA100. Cable Select is known to be unreliable, so it is best not to use it - make sure that you have the proper ATA100 cable and then try jumper-ing the drives properly. I would try getting this right with only the Hitachi drive connected first - leave the others off for now. Back tomorrow - I'm on GMT and it's 00:35 hrs! (I think Sweden must be on GMT+1) Ian. 8) |
Title: Re: Comparing HDDs - strange results Post by Christer on Mar 9th, 2004 at 4:39am
Yes, I have the 40-pin, 80-conductor cables. As a matter of fact, the "modern" round variant which should improve air circulation in the case but I don´t know about that. A degree maybe ...... ::) ...... but the scientists still debate whether it´s a degree Celsius or a degree Fahrenheit!
I use them because they are slightly longer. If I use the flat ones, one of them is stretched over its length and puts a mechanical stress on the connectors. Cable Select only works with the 80-conductor cables which have one conductor grounded on the Slave connector but not on the Master connector. My devices have always been detected correctly on CS and since the computer doesn´t boot with any other jumping on the HDDs, it would be a dead end even trying. When I was experimenting with different combinations of hardware on the controllers, to find out if Independent Device Timing was working with my motherboard, I drew the conclusion that I had used up all my luck for a while ...... 8) ...... not breaking any connectors. I´ll make one test, though, which will be to disconnect all other devices but the 7K250 and see what happens. As I mentioned earlier, I believe that it´s a problem with the software (Ghost), not the hardware. Christer, who will leave (almost) nothing untried |
Title: Re: Comparing HDDs - strange results Post by Ian Dunster on Mar 9th, 2004 at 8:22am
Hi Christer.
'the computer doesn´t boot with any other jumping on the HDDs' This is NOT right! Can you try another cable, as if the machine cannot boot WITHOUT using Cable Select then somethings definitely wrong! - there may be a setting in the BIOS to disable CS. Try using a flat cable with the drive jumpered and propped-up inside the case, so as not to strain the connections - If the PC still will not boot then it looks like you have a hardware problem (cable, drive or controller) - you must get the PC to boot using the jumpers before you can sort-out the speed problem. Let us know what happens! Ian 8) |
Title: Re: Comparing HDDs - strange results Post by Christer on Mar 9th, 2004 at 8:33am
I have created and checked another Image, this one of a partition on the 60GXP.
A reminder of my partitions: 7K250 - C: - D: - E: 60GXP - F: - G: This time I created an Image of F: to E: as well as G: with the results below: Target partition E: - create in 10min 41sec at 136 MB/min - check in 9min 59sec at 145 MB/min Target partition G: - create in 4min 14sec at 342 MB/min - check in 3min 43sec at 390 MB/min The different Image gave slightly different rates but it definitely rules out the read-write theory (different HDDs or different partitions on the same HDD) and points towards either some unknown (to me at least) feature of the 7K250 or some bug in Ghost. Maybe I´m lazy and/or stupid but I wont bother disemboweling the computer as You suggested, Ian, since I´m 99.99% certain of the outcome. As I mentioned before, I have powered off the 60GXP in the rack, leaving the 7K250 alone on the Primary, with the same results. Christer By the way, I started a thread (http://forums.storagereview.net/index.php?showtopic=14374) over at StorageReview (http://www.storagereview.com/index.html). A Guy over there was adamant on the read-write theory and that´s why I did the test to prove either him or me wrong. |

Hi Ian!
We were typing at the same time but You hit the button sooner! Quote:
Oh YES, it is! When doing the experimenting on Independent Device Timing, I tried all combinstions of hardware, cables and jumping. No matter which cable was used, the Primary Master was only detected if it was jumpered as Cable Select. It was not detected jumpered as Master or "Force Slave Present". The reason for trying FSP was the empty rack connected to the Primary Slave (I had not yet taken delivery of the new HDD at the time). Maybe I´ll sit down and think about it. The HDD that wasn´t recognized as PM was the 60GXP. Maybe the 7K250 is different? I wouldn´t think so but OK, I´ll give it a try! Christer |

Hi Again!
No matter which cable was used, the Primary Master was only detected if it was jumpered as Cable Select. It was not detected jumpered as Master or "Force Slave Present I still think this is NOT right!! Any and every drive SHOULD work using the jumpers - I still think you have something wrong somewhere. When you have the time (and feel like it!) disconnect ALL drives and then try it with just the Hitachi connected with a FLAT cable (i.e., NOT the cable you usually use) Check the BIOS to see if there is anything to do with CS and if so, DISABLE CS. Then you can start trying to find out why the drive only boots when using CS. USING JUMPERS IS THE DEFAULT AND SO SHOULD ALWAYS WORK - IN ADDITION, CABLE-SELECT IS KNOWN TO BE UNRELIABLE! (I'm NOT shouting here! :)) You can start by connecting the drive to IDE2 (as long as nothing else is connected, it will still be able to boot from IDE2) and see if it is a fault with the controller or motherboard. You can also try clearing the BIOS and letting it detect the drive again (make a note of your BIOS settings and then power-off and take out the back-up battery - wait five minutes and then re-insert the battery, power-up and re-enter your BIOS settings - this will force a clean detection of your hardware, i.e. your drive. From your first post it seems that the drive has been under-performing from the start - this may help. Ian. 8) |
Title: Re: Comparing HDDs - strange results Post by Christer on Mar 9th, 2004 at 10:52am
Ian,
while You were typing and posting, I was doing almost exactly as You suggest! 1) I jumpered the 7K250 to Master and restarted the computer which booted OK. Shut down and next, I removed the 60GXP physically from the rack and restarted the computer which booted OK. Obviously there was something not quite right with the firmware on the 60GXP when that one didn´t boot jumpered to Master. (It only occured after connecting the empty rack to the Primary Slave connector.) The 60GXP has since received an updated version of the firmware but it will never again have an Operating System installed on it so, we will never know. You were right that it was wrong but I was not wrong that it was right since it was a fact ...... ;D ...... ! 2) I physically disconnected all drives apart from the 7K250 and booted from the Ghost Boot Disks and ran a check ...... :'( ...... which was a slow as before, no change, not even a second quicker. I did not dig out the old flat cable since I am 100% sure that there is nothing wrong with the ones that I use. Tried all combinations of hardware and cables when testing Independent Device Timing. 3) Now on to the things I didn´t do: Quote:
Doesn´t the DEVICE set it self to either Master or Slave, depending on which connector, when using Cable Select? I dont think that happens on the motherboard but I´ll shut down and restart to check. Quote:
Since the 60GXP worked OK on IDE1 as the single HDD (Master) on that controller and it still works OK on IDE1 as Slave to the 7K250, I think that I know the result of trying to connect it to IDE2 Quote:
Well, that´s possibly the last stone to turn but it would mean getting down on the floor again ...... >:( ...... ! Since I don´t believe that it will work, I will probably have to sit down and reassure myself that it should be done, just to rule out the last (?) possibility. Quote:

Hi Again Christer.
I only mentioned changing the cable to see if it was the cause of the CS/jumper problem - obviously it now works OK! It would appear that unless you have a fragmentation problem, then it must be as you say - a problem with Ghost itself. (with a much larger cache the Hitachi drive should be noticeably faster) I wish I could remember where I had a Ghost Error Report, but I last got one over a year ago, (when I started using Ghost) and I can't remember how to get one! The error report would at least confirm that Ghost is using DMA. I'll do a bit more thinking! Ian 8) |

Hi again, Ian!
I´ll have a look in the Ghost manual to see if anyting is said on this matter. The promised Images (no, not the Ghost variant) below, there are some dips during Quick Linear Read and Buffered Read due to unknown interference. I only disconnected from Broadband and disabled Norton AntiVirus and Norton Personal Firewall. Probably should have been more thorough. Christer |

I thought that Ghost needed to use that method as well as DMA, but they appear to be mutally exclusive! The only thing I can now suggest is trying out the various switches that control the disk access method, and seeing if there is any difference. Ian ??? |

Ian,
I´ve tried these combinations: -ffx -fni -ffx -fnx - ffi -ffi (which is the default Ghost choice of its own) The only thing that happens is that one Active substitutes the other. No change in performance, though. I think it´s time for a chat with Symantec Support.

When performing a Ghost BackUp of my primary active partition, the rate at which it is performed turns out to be disappointingly slower using an external HDD connected via USB 2.0 as a destination contrasted to the exact same task where a logical drive in the extended partition onboard the same internal HDD is the destination.

It's referring to 'Write Behind'
This means that the data to be written to disk is kept in memory and not actually written when the program reports it has been written, e.g. when something is saved, or the program exitted - the data is written when the system can spare the time - it writes BEHIND (after) the actual program says it has finished writing.

Norway is a small country bordering to Sweden, Finland and Russia. The nature is quite beautiful with ondulating landscape in the south, developing into mountains towards the north. The only drawback is that the price level is rather high, approximately 1½-2 times the level in Sweden. Some people actually work in Norway but live in Sweden, taking the benefit of higher wages and lower living expenses on the respective side of the border.
We were in Vågå which is a small community within the Jotunheimen National Park ( http://www.lonelyplanet.com/mapshells/europe/norway/norway.htm ) with the two highest mountains in Norway, Glittertind (2464m MSL) and Galdhöpiggen (2469m MSL). We were taking off from (and landing back on) a frozen lake, Vågåvattnet, at 370m MSL. I made a flight, releasing from the tow plane at 1.200m GND and the highest altitude I reached was 6.600-6.700m GND. If You add the 370m starting altitude, You´ll get approximately 7.000m MSL which is the limit for the quite simple oxygen equipment we use in gliders. You can fly higher but then You need to get personally adapted equipment, emergency oxygen and take tests in an under pressure chamber. That flight earned me a diamond in my badge for a 5.000m altitude gain above the lowest point after release from the tow plane, well, 5.513m to be exact ...... ;D ...... We are utilizing waves to gain altitude. The waves are formed under certain conditions. You need to have a positive wind gradient with increasing altitude (wind speed increasing with the altitude) and an obstacle (a mountain) to get the air to start undulating like sinus waves. If a second obstacle (another mountain) is in the path the wave pattern is augmented. The positive wind gradient makes it increase its amplitude to great hights. Christer By the way, MSL = above Mean Sea Level and GND = above Ground. |

Title: Re: Comparing HDDs - strange results Post by Christer on Apr 1st, 2004 at 5:12am
In the mean time, I´ve been juggling connectors and checked my smallest Image of 1.026 MB on different hardware setups.
First, a reminder of the hardware setup that I normally use and the rates: Primary Master - 7K250 - 143 MB/min Primary Slave - 60GXP - 425 MB/min Secondary Master - CD-R/RW Secondary Slave - DVD-ROM Next, after juggling connectors: PM - 7K250 - 143 MB/min PS - DVD-ROM SM - 60GXP - 135 MB/min SS - CD-R/RW The reduced rate for the 60GXP indicates that in DOS environment, it makes a difference if a UDMA device is mixed with a non-UDMA device on the same channel. PM - 7K250 - 143 MB/min PS - none SM - 60GXP - 425 MB/min SS - none The restored rate for the 60GXP supports the mixing theory. The 7K250 alone on Primary, nothing on Secondary - 143 MB/min The 7K250 alone on Secondary, nothing on Primary - 137 MB/min There is a slight difference between the channels but I don´t know why. Maybe it´s performance scatter? Christer By the way, someone over at the StorageReview forum, told me that his 160 GB PATAs work well, imaging from the one to the other. I have asked him what he conciders to be well. |

You might find this of interest... I think the problem may be a compatibility issue between the various hard drives and the hard drive IDE controller on the motherboard's chipset, and how the chipset's controller is implemented by the motherboard's maker, rather than the hard drive itself or the Norton Ghost program. Here's why I think that.... My setup: I have an Abit KG7-Raid motherboard. It has two IDE hard drive controllers--the standard VIA VT82C686B southbridge controller chip, and a built in HighPoint 370/372 Raid controller chip which can be used either as a Raid controller or just another IDE controller for additional hard drives. Each of the controller chips has the standard primary and secondary channel, and each channel can have a master and a slave device. I have the following hard drives: a matched pair of Seagate 120 GB, model ST3120026A one IBM Deskstar 40 GB, model 60GXP (same model that you have--it's actually made by Hitachi and was private labeled as an IBM) one Hitachi Deskstar 40 GB (A warranty replacement from Hitachi for an IBM Deskstsar 60GXP that failed last month) So, I can create a large number of combinations of hard drive/controller match-ups. I tested using the Image Creation speed rather than the Image Integrity Check speed, and in each case I'm reporting below, I'm using Image Creation without Compression. So here's what I found... If I had the Seagate 120 GB on the HighPoint primary channel as master and I tried to image to either the IBM 40 GB or the Hitachi 40 GB on the VIA secondary channel as slave, the image creation speed was 115 MB/min. But, leaving the Seagate 120 GB on the HighPoint primary channel as master, if I switched either the IBM 40 GB or the Hitachi 40 GB to the HighPoint secondary channel as slave, and I imaged from the Seagate to either the IBM 40 GB or the Hatachi 40 GB, I now got an image creation speed of 1176 MB/min. Quite a dramatic increase! Now, again leaving the Seagate 120 GB on the HighPoint privary channel as master, I hooked the second Seagate up to the VIA primary channel as master, when I imaged from the Seagate 120 GB on the HighPoint controller to the Seagate 120GB on the VIA controller, I got an image creation speed of 1195 MB/min. And when I imaged from the Seagate on the VIA controller to the Seagate on the HighPoint controller, I got an image creation speed of 1363 MB/min (which was the fastest combination I found). I also imaged from the Seagate on the VIA primary channel as master to the Hitachi 40 GB on the HighPoint secondary channel as slave and got an image creation rate of 1274 MB/min. However, if I put one of the Seagates on the VIA primary channel as master and the other Seagate on the VIA secondary as master, I now got an image creation rate of 128 MB/min! I did a couple Image Integrity Checks along the way, and they all had speeds that were between one third to one half again faster than their corresponding Image Creation speeds. So, all the hard drives showed the potential to create images at a high speed and Ghost could deliver the high speed with each of the drives, but it depended on which controller the hard drives were matched up with. All the hard drives worked well if they were on the HighPoint controller, but only the Seagate showed a high creation speed when it was on the VIA controller's primary channel as master and imaging to and from other hard drives on the HighPoint controller, but not other drives on the VIA controller. I'm betting it's a VIA controller issue under native DOS. And the problem may not exist under Windows because you're then using the 4in1 VIA drivers. You used test programs to check the speed of your drives--were those programs under Windows, or do they check things under native DOS? I don't know the answer to this, but what 'driver' is the VIA IDE controller using under native DOS when you're not using Windows? It's interesting that it's your IBM Deskstar that is showing the better performance while my IBM Deskstar is showing poorer performance when on the VIA controller--that's why I think it's how the motherboard maker has implemented the chipset on their particular board that's making a difference being as I believe we both have the same VIA controller, but we have different brands of motherboards. Given all this, it looks like one might do well to 'test drive' several different brands of hard drive to see which one gives the better results before making a 'final' purchase--however, not an easy thing to do. And I wonder if any folks with an Intel based chipsets have similar issues? There must be some other folks with integrated Raid chips from HighPoint or Promise, or are using PCI add-on IDE controller cards, either with Raid or just for additional hard drives, either on a VIA chipset board or a Intel chipset board--any other input would be interesting to hear as to performance depending on which controller one uses with which hard drives. |

When I tried to post-it, I experienced some sort of Internet slow down, and the post-it command timed out and the whole thing was lost. But, I had composed it using 'WordPad' and had just 'copied' and 'pasted' to the reply area. It was no problem re-copying and pasting and re-posting. |

Well guys, it's not the first time and I try to remember to either do the typing in Word or back it up there. When using a lot of quotes, I tend to NOT do it the safe way but I guess I'll remember now ...... :-/ ...... for a while.
Now, to my thoughts and comments: Quote:
I don't remember if I mentioned my system basics but it is EPOX 8KTA3 with VIA KT133A+VT82C686B. I actually tried to update the 4in1 drivers but that was out of pure frustration, since they don't get loaded when not starting Windows. That action was, of course, in vain. Quote:
It seems like Your Hitachi built 60GXP differs from my IBM built. The rates are approximately the same as for my 7K250 so; does Your 60GXP have different firmware or is it possible that it has the "7K250"-electronics? There must (?) be a reason for the "no difference" between Your Hitachi/IBM. Quote:
Yes, it definitely points to the VIA chipset. That rate is more than three times higher than on my computer. Quote:
This definitely suggests a hardware conflict, VIA - Hitachi, which is supported by ...... Quote:
...... which indicates that HighPoint - Hitachi is fine. Quote:
This indicates that the problem is basically with the VIA chipset. The conclusion I drew from my test results was that the problem was when the target partition was on the 7K250. That is concurrent with Your test result in my first quote under which the 7K250 was the target on the VIA controller. If You find the time, could You do a test with the 7K250 as the target on the HighPoint controller? If that works better, then I believe that You have nailed VIA to the wall! Quote:
My results show smaller differences (6-12%), ~136 MB/min creating and ~145 MB/min checking with the target on the 7K250, ~342 MB/min creating and 390 MB/min checking with the target on the 60GXP. Even my "good" figures are low compared to Your "good" figures which also points to VIA. Quote:
As I mentioned and asked about before, If You find the time, could You do a test with the 7K250 as the target on the HighPoint controller? That's the one test You "missed". Quote:
It was the plug-in in AIDA32. It only performs tests under Windows. Quote:
Neither do I know but a guess would be which ever driver that is loaded by the boot disk which probably is none. That leaves us with what is in BIOS. Quote:
Now, You're confusing me. I was under the impression that there was no difference between Your 7K250 and Your 60GXP. See my comments on Your test #1. Quote:
I agree! If anyone out there is willing to do a couple of tests, the results would be very welcome!! Christer |

Quote: "Now, You're confusing me. I was under the impression that there was no difference between Your 7K250 and Your 60GXP. See my comments on Your test #1." I do not have a 7K250 Hitachi. I have a 40 GB Hitachi Deskstar that was sent as a current 'equivalent' replacement for the failed IBM Deskstar 60GXP and it has a manufacture date of March, 2004. And I have an older IBM Deskstar 60GXP. Both the Hitachi Deskstar and the IBM Deskstar performed the same. If either was on the VIA controller's secondary as slave, they each got the 115 MB/min image creation speed. If either was switched to the HighPoint controller's secondary slave position, they got 1176 MB/min image creation speed. What I was trying to say was that your IBM Deskstar 60GXP on your system using the VIA controller was performing better than my IBM Deskstar 60GXP on my system's VIA controller. Quote: "If You find the time, could You do a test with the 7K250 as the target on the HighPoint controller? If that works better, then I believe that You have nailed VIA to the wall!"

I got this one right but I've got to ask: What do You mean by "private labeled as an IBM"? Mine was manufactured in march 2001 by IBM-Thailand and has the same Model # and Part # as Yours. There is no firmware version mentioned but I have updated my 60GXP to the version recommended by IBM. Quote:
Yes, I've been there but Hitachi inherited the warranty commitments from IBM which means that IBM HDD's are listed too. Quote:
I misunderstood "Hitachi Deskstar 40 GB" as a 7K250. That model too is named Deskstar. Quote:
That is news to me. I didn't know that the 60GXP is still manufactured but I take Your word for it. Other replacements for failing 60GXP's that I've heard about have been either a refurbished IBM 60GXP or a new Hitachi 7K250 of the corresponding capacity. Quote:
Yes, now that I have sorted out Your hardware ...... ;) ...... do I understand what You mean. The possible difference regarding firmware version doesn't matter. I noted the same transfer rates before as I do after the update. The rates of this drive fitted my misunderstanding that You had a 7K250. It was actually somewhat slower than my 7K250. Quote:
Yes but my thought was which rate was acchieved with the Hitachi on VIA as source drive and one of the Seagates as target drive on HighPoint. That would sort out if it is a write problem only or a read problem as well. However, since it isn't a 7K250, it isn't an important test from my perspective but it would still be interesting. On my system, it is both. From the 60GXP to the 7K250 is slow. The other way, is quick(er). From one partition to another on the 7K250 is slow but from one partition to another on the 60GXP is quick(er). Checking an Image on the 7K250 is always slow, on the 60GXP it is quick(er). The general agent for EPOX in Sweden is located 20 km away from my home. Maybe I should give them a call and possibly get my PC over there to let them have a look. Christer |

I did not know there was a firmware upgrade available! How do you 'flash' a hard drive--never done that one. Quote:
I think I'm wrong here! I thought your 7K250 model was specific to your 120 GB drive--but, I now see that it applies to several different capacity hard drives after looking further at the Hitachi site. The reason I got this wrong is that I no longer have the hard drive on my machine. My daughter's hard drive failed two weeks ago and I gave her that one to take back to college, so I could not look at the label. My replacement 40 GB Hitachi Deskstar must be a Hitachi 7k250. But regardless of the name, the performance results are as previously posted. Quote:
Yeh-Hitachi 'inherited' the IBM warranties because they're the ones who actually made them! Quote:
You're right, I did not do that test. I realized afterwords that that would have been a good confirming test. But I can not use the Hitachi hard drive for the moment because my daughter has it. And actually, I cant try the IBM right now either, because I have returned it to Hitachi for warranty replacement as well (its platter spin sound was becoming louder than the case fans)!!!! When I get the replacement hard drive (probably in about a week), I will run that test and report it back here. Quote:

My logic wasn't all off then. Your rates correspond to my rates for the 7K250. The question is, why the rates of Your 60GXP differs from the rates of my 60GXP? I can't help thinking about the fact that Your IBM Deskstar was manufactured by Hitachi and has the same performance as the Hitachi Deskstar. The model # and part # speak against this but it seems like Your Hitachi manufactured IBM Deskstar has the 7K250 electronics and firmware. Quote:
I don't think so. Most 60GXP's were IBM manufactured, I didn't even know that Hitachi was involved before the purchase. When a company buys another, it buys all assets and obligations, including warranties. Quote:

I have thought about that and came to the conclusion to not do any tests on harddives belonging to friends. None of these drives are empty. Most of them are in single harddrive systems. As I mentioned in a previous post, I'm going to buy a second harddrive for a friend. I had planned to get an identical 7K250 to mine and do tests on that one before installing it in my friends system. That would be safe but now, I believe that I know the outcome. The test would be to get better rates from the second harddrive and identify my 7K250 as defective but Your rates indicate that the rates are "normal" on a VIA chipset. Christer |

Once again, I could be wrong about who manufactured the IBM labeled Deskstar hard drive back in 2001. When I was looking for warranty info, I went to this website: http://www.storage.ibm.com/hddredr/hddredr_w.html Based on the info about the 'IBM FRU Number', I made the leap of faith that any drive without the IBM FRU number and now supported by Hitachi, must have been actually made by Hitachi, and that's why Hitachi took over the warranties. And drives with the IBM FRU number must have been made by IBM (although, I'll bet IBM contracts out to others the actual manufacturing). And I assumed Hitachi did not want to take on those warranties because they did not make those hard drives. So, if you have information that says IBM Deskstars were made by IBM and not Hitachi, I really cant say I know otherwise except based on what I said above. |

Yesterday, I received an update from Hitachi:
Quote:
It's interesting that he/she mentions having found his/her way here and to StorageReview. I don't remember having mentioned neither Radified nor StorageReview to Hitachi but I did mention Radified to EPOX. Do they browse the web in general or has Hitachi and EPOX been in contact with eachother on this issue? He/she comments on the firmware update to the 60GXP and claims that it won't work with my drives. I don't know if he/she refers to the same update, which was explicitly to "cure" the reliability issue with the 60GXP. The fact that I did the update, has no bearing on the speed issue. I did that update before the 7K250 was installed, after a recommendation on StorageReview in order to possibly prolong the life of the 60GXP. The "scan and check" utility found the 60GXP and identified the firmware version as in need of an update to "cure" the reliability problem. The flash utility updated the firmware and a succeeding "scan and check" again found the 60GXP and identified the firmware as OK. I will send a reply to Hitachi later today but I will not quote it here. By the way, Hitachi's comment on them building drives for IBM indicate that NightOwl was right but as I understand it, generic drives are sold to computer manufacturers, not to end users like us.

It's taken me a while to get back to this because, unlike the first replacement drive which came from California, and took only 2 days to arrive, this one came from Malaysia, and took 9 days to arrive. Hmmmm... our global economy! But now I have the Hitachi replacement hard drive and have done some more testing. First off... Quote:
Well, maybe that plant was not really closed! The new replacement hard drive from Hitachi is labeled 'IBM Deskstar made in Hungary for Hitachi Global' with a manufacturing date of 'May-04' and with a sticker that says 'Serviceable Used Part.' And I say out loud with what appears to be a forced, unnatural smile, 'Greeeat...a serviceable used part IBM Deskstar made in Hungary for Hitachi Global', and the bubble above my head shows what I'm really thinking, 'Oh, s--t, a serviceable used part IBM 'DeathStar' made in Hungary for Hitachi Global.' :D Thanks for that information quoted above, Christer. Now I have more confidence in the IBM Deskstars, having replaced the first two that were made in Thailand by IBM Storage Products, Ltd. Oh, well...so far its spin is quiet, and I can only just hear the heads clicking when there's heavy access, like when creating a Ghost image...unlike the Seagates that are totally silent! The refurbished 40 GB hard drive from Hitachi is model # IC35L040AVER07-0 and the part # is W: 07N6654, and no firmware version indicated. I'm going to call this replacement the 'used IBM' drive. So here's the results: In all cases, I'm using image creation speed, and no compression. Christer--you wanted to know the image creation speed with the 'used IBM' 40 GB hard drive on the VIA controller (I know you preferred the Hitachi 7K250 40 GB model, but I don't have that now as previously mentioned) and sending the image to the Seagate on the HighPoint controller. Well, I noted that I had put the previous IBM Deskstar (not the 'used IBM'), and the Hitachi Deskstar on the VIA secondary channel as slave, while the Seagate was always on the VIA primary as master, so I put the 'used IBM' on the VIA primary channel as master and sent the image to the Seagate on the HighPoint primary as master and the creation speed was 1114 MB/min. I sent the image the other direction leaving the hard drives hooked up to the same controller positions, from the Seagate to the 'used IBM' and got a 404 MB/min creation speed! Next, I changed the 'used IBM' to the VIA secondary channel as slave as I had things setup on the original tests that I previously reported and imaged from the 'used IBM' to the Seagate on the HighPoint primary as master and got a creation speed of 991 MB/min. And reversing the imaging direction from the Seagate to the 'used IBM', I got 132 MB/min. That creation speed was some better, but very similar to the previous results when I got 115 MB/min when using either the Hitachi 7k250 or the original IBM Deskstar and imaging from the Seagate on the HighPoint primary as master to either the Hitachi 7k250 or the original IBM Deskstar on the VIA secondary channel as slave. I then put the 'used IBM' on the HighPoint secondary controller as slave and left the Seagate on the HighPoint primary as master and imaging from the Seagate to the 'used IBM' gave a creation speed of 1163 MB/min, and sending the image from the 'used IBM' to the Seagate gave a creation speed of 889 MB/min. So, again it appears to still be the case--drives on the HighPoint worked well together, but trying to send an image from a drive on the HighPoint to a drive on the VIA controller resulted in a much reduced performance, while sending an image from a hard drive on the VIA controller to the HighPoint was much better performance. And as previously noted, if both drives were on the VIA controller, the performance was poor. Both Norton Ghost and the hard drives show the ability to perform together at high speed, but it depends on the their position on the controller and which controller they're on...I still think the results are pointing at the VIA controller as being the problem. |

thanks for posting back! I think that this mammoth thread is a record breaker and we are probably far from the finish line!! Quote:
Maybe I'm totally wrong but is it possible that it was originally manufactured by IBM in Hungary and subsequently refurbished elsewhere by Hitachi? In the latest correspondence, the "guys" at Hitachi confessed to lurking here and since they have the answers, I invite them to join our discussion. The "guys" at EPOX came off the starting-blocks rather quickly but since then - nothing. I hope that they too are "on the case" and it's better to get a solution in due course than a quick "evasive action". The outcome of all this will have an influence on my next purchase decision ...... :-/ ...... Quote:
These two tests indicate that it is a write problem and not a read problem. The task is slower when the IBM is the target. I haven't found any mention of to which controller Your optical drives are connected. I assume that they are out of the picture but an optical as VIA Secondary Master would explain the drop from 404 to 132 with the IMB as the target, if VIA Primary Slave had nothing or another HDD connected. (As a side note; I have noticed that mixing a HDD and an optical drive doesn't affect the performance of the HDD when under Windows and 4in1-drivers but under DOS, the performance of the HDD drops to that of the optical drive.) Quote:
This points almost all fingers, including the thumbs, to VIA but this, from Your first tests: Quote:
indicates that the IBM/Hitachi incompatibility could possibly be resolved by a "simple" modification of the HDD firmware. I mean, there is no incompatibility with the Seagate firmware. The "general" differences of the rates in my system compared to the rates in Your system can probably be explained by the "general" performance differences of our respective system. My processor is an AMD Athlon Thunderbird 1GHz/266MHz and my guess is that Your processor is in the 2.5-3 GHz range. Christer |

I was out of town for a few days and have been busy with other things, but to respond to your last post... 'And now for the rest of the story....' I did several additional imaging test when I was testing the 'used IBM' and regarding your comment: Quote:
I repeated the tests using the Seagates... I wanted to confirm my findings, and low and behold, the results were different this time!!!! Computers, ya gotta love 'em! I put one Seagate on the VIA primary channel as master and one Seagate on the HighPoint primary as master and sending the image from the VIA Seagate to the HighPoint Seagate, I got a creation speed of 983 MB/min (slower than the 'used IBM to Seagate of 1114 MB/min!), and now when I imaged from the HighPoint Seagate to the VIA Seagate, I now got 142 MB/min creation speed! I do not know what has changed to make the results different this time, but I tried serveral times and each test was similar in results! If you recall, on my original post I got an image creation rate of 1195 MB/min going from the Seagate on the HighPoint to the Seagate on the VIA controller, and got 1363 MB/Min going from the Seagate on VIA to the Seagate on the HighPoint controller. Quote:
I have a CD-writer on VIA's primary as master, and a DVD-Rom drive on VIA's secondary as master. I also did tests where I specifically either left them connected or disconnected to see if the image creation speed varied. On my system, it did not matter if the optical drives were connected or not, and it did not matter if the optical drives were connected and sharing the same channnel or on separate channels from the hard drives. However, most of the test results were with the optical drives disconnected. Quote:

Title: Re: Comparing HDDs - strange results Post by Christer on Jun 21st, 2004 at 10:16am
Hello all,
it’s time to bump this thread with a bit of recent research results! I believe that I have mentioned a friend, for whom I was shopping for a new HDD. Well, I finally got around to it and guess what …… ::) ...... he went by my recommendation to get a Hitachi HDS722512VLAT80, 120 GB - 8 MB cache PATA, identical to mine including the same firmware. I borrowed it for a day or two before helping him to reinstall his system on the new drive. I formatted it to F: - 12 GB NTFS, G: - 90 GB NTFS, H: - 18 GB FAT32. Mine is identical but with drive letters C/D/E. From C: - NTFS to H: - FAT32 was the same low rates as before, creating at 136 MB/min and checking at 145 MB/min. From C: - NTFS to G: - NTFS, creating was at 809 MB/min and checking was at 2480 MB/min! I put my own backup drive (IBM 60GXP) back in the rack and it has the partitions F: - NTFS and G: - FAT32. Previous results for C: - NTFS to G: - FAT32 was creating at 343 MB/min and checking at 390 MB/min. Now, I tested C: - NTFS to F: - NTFS. Creating was at 802 MB/min and checking at 2229 MB/min! This was a surprise and a test that should have been done a long time ago! Could it be that Ghost’s new-won ability to create Images directly to NTFS partitions has hampered its ability to create Images to FAT32 partitions on some hardware configurations? Comparing the differences for creating to the differences for checking, indicates to me that it's more of a read problem than a write problem when FAT32 is involved. ======================== Now, I went to visit another friend (or rather his computer ...... ;) ...... don’t tell him) whom I mentioned in my previous post. To recapture his setup: - ASUS P4P800 motherboard with Intel i865PE chipset - P4 2.8GHz/800MHz - 2x512 MB PC3200 dual channel - one Seagate 7200.7 160 GB SATA (ST3160023AS) as boot drive with two partitions, C: - NTFS and D: - NTFS - one Seagate 7200.7 plus PATA (ST3160023A) as backup drive with two partitions, E: - NTFS and F: - FAT32 From C: - NTFS to E: - NTFS, creating was at 885 MB/min and checking was at 2959 MB/min. From C: - NTFS to F: - FAT32, creating was at 831 MB/min and checking was at 1611 MB/min. The difference for creating is ~6%, not ~600% as in the case of the Hitachi on my system. The difference for checking is ~84% which supports my suspicion that it's a read problem when FAT32 is involved. ======================== Now I took his PATA out from the rack and installed the 7K250. Those partitions now became E/F/G. From C: - NTFS to F: - NTFS, creating was at 895 MB/min and checking was at 2145 MB/min. From C: - NTFS to G: - FAT32, creating was at 859 MB/min and checking was at 1674 MB/min. A difference of ~4% for creating which is an acceptable figure compared to the ~600% difference on my system. The ~28% difference for checking is lower than for the Seagate but still indicates a read problem. ======================== NOTE – OFF TOPIC As a side test, from within XP – Windows Explorer, to compare the performance of the Seagate PATA to the performance of the Hitachi PATA: Seagate - moving the Image (4340 GB) from F: - FAT32 to E: - NTFS took 9min03sec which equals 480 MB/min. Hitachi – moving the Image (4340 GB) from G: - FAT32 to F: - NTFS took 4min40sec which equals 930 MB/min. This actually puts the rates during Ghost operations in a perspective. ======================== Christer |

El Pescador,
I hardly ever read topics on USB or FireWire since I don't have such devices. However, it seems like there is a connection between my issue and Your issue and the common denominator is FAT32. As tested according to my latest post, all FAT32 target partitions were on an extended partition as logicals. All NTFS source partitions were primary partitions. That combination wasn’t among Your tests. I hope that the guys at Symantec are following this thread and the people at Hitachi and EPOX too for that matter. It seems to be both software related and hardware related but I currently lean towards Ghost being the culprit with different effects on different hardware. In my latest post, I forgot to mention that when installing the new Hitachi in my friends system, a WD800 was relegated to backup drive. I made the WD800 into one extended partition with one logical NTFS and one logical FAT32. The notes I took were mislaid but from memory it was much slower to the FAT32 partition than to the NTFS partition. The difference was of the same magnitude as for my IBM 60GXP. The strange (?) thing is that the computer in question (Fujitsu Siemens) has an Intel chipset, either i845/82801BA or i850/82801BA, which sort of complicates things since I, a few weeks ago, thought that we had VIA nailed to the wall.

Okay--now which of the three NTFS versions were you using....? (Just kidding...kind of ;D) Was up past mid-night running test Ghost images :D. BTW, I looked at my notes and I could not determine for sure whether I was imaging to a NTFS partition or to a FAT32 partition on the various previous tests. I suspect most of the tests were imaged to a FAT32 partition however. Here's the results-- I re-partitioned the 'used IBM' so it had an extended partition only with a logical drive formated as a FAT32 partition and a logical drive formated as a NTFS partition. In each case, I'm showing the final image creation speed, and using 'no compression' to create the images. The Seagate 120 GB hard drive was on the HighPoint Controller, primary channel as master and the 'used IBM' was on the VIA Controller, primary channel as master: Seagate NTFS >>> 'used IBM' NTFS 994 MB/min * Seagate NTFS <<< 'used IBM' NTFS 1071 MB/min Seagate FAT32 >>> 'used IBM' NTFS 946 MB/min * Seagate FAT32 <<< 'used IBM' NTFS 1040 MB/min Seagate FAT32 >>> 'used IBM' FAT32 442 MB/min * Seagate FAT32 <<< 'used IBM' FAT32 962 MB/min Seagate NTFS >>> 'used IBM' FAT32 434 MB/min * Seagate NTFS <<< 'used IBM' FAT32 846 MB/min Imaging to the 'used IBM' on the VIA controller was over twice as fast if the partition was in the NTFS format to receive the image. ************************ I then switched the 'used IBM' from the VIA Controller to the HighPoint Controller, secondary channel as slave, and left the Seagate on the HighPoint Controller, primary channel as master: Seagate NTFS >>> 'used IBM' NTFS 1206 MB/min Seagate NTFS <<< 'used IBM' NTFS 1050 MB/min Seagate FAT32 >>> 'used IBM' NTFS 1216 MB/min Seagate FAT32 <<< 'used IBM' NTFS 1020 MB/min Seagate FAT32 >>> 'used IBM' FAT32 1184 MB/min Seagate FAT32 <<< 'used IBM' FAT32 976 MB/min Seagate NTFS >>> 'used IBM' FAT32 1267 MB/min Seagate NTFS <<< 'used IBM' FAT32 1017 MB/min Now, with the VIA controller out of the picture, the imaging to a FAT32 partition vs the NTFS partition difference is pretty much gone. Also, in general, it looks like the NTFS is some faster. Whether this is due to Ghost being optimized for NTFS or if it's what Microsoft intended to improve with the introduction of the NTFS format, someone else who knows more than I would have to help out there. |

NightOwl,
I was contemplating a new round of e-mails to Symantec, Hitachi and EPOX but I believe that I would fry my brain in the process! We have two VIA chipsets (mine and Yours) giving us trouble and the Intel chipset on the other computer that I mentioned displaying slow performance on FAT32 may require some more investigation. I will find out the exact computer model and go Google on it. Judged by Your latest results, it seems like the key words are VIA, FAT32 and TARGET PARTITION, which equals slow performance. Christer |

As you recall, my first tests with the Seagate hard drives showed very good results whether on the HighPoint controller or the VIA controller. When I repeated the test, the results were much different. Quote:
Well, after your test results of imaging Fat32 vs NTFS formated partitions, I decided to go back and repeat the tests using just the Seagates and varying the formatting of the partitions and here are the results: In each case, I'm showing the final image creation speed, and using 'no compression' to create the images. One Seagate (120 GB) hard drive was on the HighPoint Controller, primary channel as master and the other Seagate (120 GB) was on the VIA Controller, primary channel as master, and the arrows show the direction of the image creation: On HighPoint---------------On VIA------------Speed Seagate NTFS >>>>> Seagate NTFS 1185 MB/min Seagate NTFS <<<<< Seagate NTFS 944 MB/min Seagate FAT32 >>>>> Seagate NTFS 786 MB/min Seagate FAT32 <<<<< Seagate NTFS 1243 MB/min Seagate FAT32 >>>>> Seagate FAT32 136 MB/min Seagate FAT32 <<<<< Seagate FAT32 1241 MB/min Seagate NTFS >>>>> Seagate FAT32 140 MB/min Seagate NTFS <<<<< Seagate FAT32 1265 MB/min Apparently, just by accident, I must have chose the best combinations to image from HighPoint to VIA or from VIA to HighPoint on my first tests. And it's clear you do not want to image to a hard drive on the VIA controller if the partition is FAT32, but a NTFS partition is quite good. ************************ I then switched the Seagate on the VIA Controller to the HighPoint Controller, secondary channel as slave, and left the other Seagate on the HighPoint Controller, primary channel as master: On HighPoint-------------On HighPoint-------Speed Seagate NTFS >>>>> Seagate NTFS 1110 MB/min Seagate NTFS <<<<< Seagate NTFS 1145 MB/min Seagate FAT32 >>>>> Seagate NTFS 786 MB/min Seagate FAT32 <<<<< Seagate NTFS 1054 MB/min Seagate FAT32 >>>>> Seagate FAT32 767 MB/min Seagate FAT32 <<<<< Seagate FAT32 1218 MB/min Seagate NTFS >>>>> Seagate FAT32 916 MB/min Seagate NTFS <<<<< Seagate FAT32 1291 MB/min Now with the Seagates both on the HighPoint controller, there are some differences (and I can only wonder why :-) ), but not the dramatic differences seen imaging to a VIA FAT32 partition. ************************ Now I put both Seagates on the VIA controller, one on the primary as master and the other on the secondary as master: On VIA-------------------On VIA----------Speed Seagate NTFS >>>>> Seagate NTFS 1171 MB/min Seagate NTFS <<<<< Seagate NTFS 1341 MB/min Seagate FAT32 >>>>> Seagate NTFS 829 MB/min Seagate FAT32 <<<<< Seagate NTFS 144 MB/min Seagate FAT32 >>>>> Seagate FAT32 131 MB/min Seagate FAT32 <<<<< Seagate FAT32 144 MB/min Seagate NTFS >>>>> Seagate FAT32 135 MB/min Seagate NTFS <<<<< Seagate FAT32 1300 MB/min Again, imaging to a FAT32 partition on the VIA controller was not the best option. So, it looks like if you have a VIA VT82C686B southbridge controller chip on your system, you would get much better performance if you image to a NTFS partition rather than to a FAT32 formated partition. |

NightOwl,
Your latest figures confirm that the issue is with FAT32 and VIA. It puts Hitachi in the clear since Your figures are for Seagates. This week I start my holidays and will be more or less separated from my computer for the next two weeks. I will not start a new correspondence with Symantec, EPOX and VIA as an addition, until I know that I will be available for their responses. I will also mail Hitachi to tell them about our findings. I will check in every now and then from other computers, though. I will keep You posted when I send the mails! Christer |

Actually, looking at the results, it seems that the newer hard drives from both Hitachi and Seagate are performing less well than the older IBM's. I'm thinking that maybe the newer hard drives have been tweaked for NTFS, and in the process, it has somehow effected the compatibility of the VIA chipset with FAT32 and the newer hard drives firmware performance. |

I've had the opportunity to do some tests on a system based on ABIT VA-10 with VIA VT8378 (KM400) / VT8235 (southbridge), AMD Sempron 2600+, 512 MB PC2700, two Maxtor Plus8 - 40 GB.
C: (NTFS) on HDD-0 to E: (NTFS) on HDD-1 Create - 860 MB/min Check - 3533 MB/min C: (NTFS) on HDD-0 to F: (FAT32) on HDD-1 Create - 248 MB/min Check - 315 MB/min If we compare that to the transfer rates from 7K250 to 60GXP: C: (NTFS) on 7K250 to F: (NTFS) on 60GXP Create - 802 MB/min Check - 2229 MB/min C: (NTFS) on 7K250 to G: (FAT32) on 60GXP Create - 342 MB/min Check - 390 MB/min The Plus8 and 60GXP are 2 MB cache drives and are both performing better, when the target partition is FAT32, than the 7K250 and Seagate 7200.7 which are 8 MB cache drives. Anyway, the tests on the ABIT VA-10 based hardware have convinced me that my next motherboard will not include anything VIA. Christer |
Title: Re: Comparing HDDs - strange results Post by El_Pescador on Aug 11th, 2005 at 1:24am Christer - Serendipity strikes again - while winding up my successful attempts to restore the temporarily-lost capability of my "purpose-built" Iomega 80GB HDD USB 2.0 External Drive to function in Norton Ghost 2003 with the stock Norton/Iomega drivers extracted from Guest.exe, I blundered into a phenomenon not unlike this thread of long standing considering the performance disparity between the NTFS and FAT32 file system formats under particular hardware configurations. To recap, after using PowerQuest Partition Magic 8 to partition the preformatted FAT32 Iomega External Drive I ruefully discovered that I was unable to restore its former capability and had become reliant on NightOwl's Panasonic Universal USB Driver routine in order to conduct Ghost 2003 operations. Suffering from a degree of neurotic obsessiveness, I was bound and determined 'to put Humpty-Dumpty back together again' - and I succeeded. The trick (CLICK HERE) is to zero-fill the Iomega disk using the Ghost 2003 DOS-based utility GDisk with the /diskwipe switch and then with no preparation whatsoever immediately submit the disk to the Seagate DiscWizard in Windows; once there, configure a single primary FAT32 partition not-to-exeed 32GB and close out followed by a reboot into SAFE MODE. Restarting DiscWizard: (1) click on the Maintenance button; (2) select Partitioning and Formatting Options; and (3) select Grow a Partition whereupon the process completes itself. Theoretically Windows XP FAT32 volumes larger than 32 GB have to emanate from other operating systems, but this DiscWizard is a "loophole" utility running inside XP that let the 16kb cluster size remain static right up until the capacity limit of the HDD was attained (luckily the Iomega HDD was Seagate-compliant, but not all HDDs are). Once all this had transpired, I began to consider if such an extraordinary reconfiguration of other FAT32 primary partitions and logical drives would reinvigorate them so as to be more on par with their NTFS counterparts. On my Dell Dimension 8100, I now have a 60GB IBM/Hitachi DeskStar IDE HDD (IC35L060AVV207-0) set up as a SLAVE inside my PC to serve primarily as a first-line repository for the Norton Ghost 2003 Backup images spun off my MASTER 120GB Maxtor SATA HDD (6Y120MO); likewise, I have an 80GB Western Digital IDE SLAVE HDD (WDC WD800JB-00JJA0) installed in my Dell Dimension 8300. With my external HDDs mounted in enclosure kits, I typically set them up as a single extended partition - no primary, no active - and split them into two logical drives of equal volume with the leading drive formatted NTFS and the trailing drive formatted FAT32; with external HDDs, I suffer no performance penalty but with internal SLAVE IDE HDDs set up exactly the same way on both my Dell Dimension 8100 and on my Dimension 8300 as well, I have been consistently experiencing poor performance with FAT32 ... UNTIL I EMPLOYED THAT CONFIGURATION DESCRIBED ABOVE, THAT IS !!! Without any tables or graphs at this stage, let me say that a routine Ghost 2003 "partition-to-image" Backup to the FAT32 logical drive on the 8100 SLAVE HDD that heretofore took 22-to-23 minutes now takes 10-to-11 minutes; albeit the same task to the SLAVE NTFS logical drive now takes 4-to-5 minutes but unfortunately there are no available logs on the pre-transition period. The situation on the Dimension 8300 is even more noteworthy: whereas heretofore a Ghost 2003 "disk-to-image" Backup to the NTFS logical drive was consuming 35-to-36 minutes, it is now taking 16-to-17 minutes in NTFS - but only 17-to-171/2 minutes in FAT32 (again, no available logs on the pre-transition period). Therefore, the question I pose to you is to what degree - if any - could a reconfiguration such as I describe above enhance or afflict the performance of HDDs tested in the FAT32 file system format back upstream in this thread. Also, a bit of an aside - the 60GB SLAVE Hitachi IDE HDD has a 2MB cache versus an 8MB cache for the 80GB SLAVE Western Digital IDE HDD. [glb]El Pescador[/glb] |

GDisk n /diskwipe only - then straight to Windows XP and let Seagate DiscWizard find the target HDD "hands-off". I have done several repetitions, and my latest twist is to let DiscWizard lay out a NTFS partition by default for a bit over half of the disk (anything over 35GB) - then lay out about 25GB which is FAT32 w/16kb cluster by default so as to leave the remainder unencumbered until the second pass in SAFE MODE using the GROW command. Then - and only then - do I go into Partition Magic 8.0 where I delete the primary 34GB+ NTFS partition (its weird, but once the primary emerged from DiscWizard unformatted!) and use PM8 to recreate it as a NTFS logical drive expanded to the maximum capacity of the HDD while sharing the single extended partition with the GROWN-UP FAT32 logical drive containing 16kb clusters.

These different modes of connection will demonstrate varying levels of performance disparity between the NTFS and the FAT32 file system format partitions ranging from NULL performance for either of the formats to NEAR-IDENTICAL performance with both formats. Toss in the concept of having a manipulated outsized FAT32 partition - on a disk with neither a primary nor an active partition - and the permutations become positively unwieldy.

My favorite "low-level formatting" tool, i.e. zero-fill routine, is included with every copy of Ghost 2003 and is a DOS-based utitlity called GDisk. The routine I use is the switch 'GDISK drive no. /DISKWIPE'. I will be glad to mail you one of my numerous copies of the Seagate installation CDs included with each retail HDD kit, but you may prefer to download the latest counterpart material from their WebSite: http://www.seagate.com/support/kb/disc/howto/use_dwse.html http://www.seagate.com/support/kb/disc/howto/use_dwse_maint.html The BIOS-tricking software is called Dynamic Drive Overlay (DDO), and despite warnings about no support will be extended to non-Seagate users, it has worked for me with Western Digital, Hitachi and whatever brand is encased in my Iomega External 80GB HDD - but it rejects my Maxtor HDDs. In fact, I was thoroughly disgusted with my three identical 80GB Western Digital IDE disks (WDC WD800JB-OOJJA0) as internal SLAVE HDDs in regard to disparity between the NTFS and FAT32 file system formats - but not when mounted in external enclosures. However, since installing the Seagate Dynamic Drive Overlay, the WDC WD800JB-OOJJA0s now outperform every other brand of HDD I have tested in the SLAVE role when performing Ghost 2003 procedures with a FAT32 logical drive on the Destination HDD. Do keep in mind that all the remarks above relate to IDE HDDs - so one caveat is that the technique may not work on every model in the Hitachi line, particularly native SATA HDDs.

The devil is in the *details*--I have lost track of exactly what you are doing-- In your reply #123 above--you created what appears to be a single FAT32 primary partition. In your reply #125 above--you create what appears to be two primary partition: 1. a NTFS partition of > 35 GB 2. a FAT32 partition of approx. 25 GB You then manipulate those partitions using PartitionMagic to delete and reconfigure them as Logical partitions in an extended partition--but the step-by-step sequence is missing--and the final size of each partition is not mentioned. And then, in your reply # 128, you modify your procedure so as to not *delete* the NTFS partition, but simply manipulate it and the FAT32 partition so as to end up with an Extended partition with the NTFS and FAT32 partition inside...but, again the step-by-step details of the sequence of steps is missing--as well as the final size of the partitions. So, of the three different configurations and steps outlined above--which one (or ones) did you want tested--and what are the missing steps and final sizes of the partitions in your outline? |
Title: Re: Comparing HDDs - strange results Post by El_Pescador on Aug 22nd, 2005 at 6:21pm
FOUR STEPS (using 160GB Seagate IDE HDD as example as it mirrors my MASTER SATA NCQ HDD):
(1) Use DOS-based GDisk disk no. /diskwipe to zero-fill the target HDD, but no subsequent GDisk operations at all; (2) Go straight to Windows XP and tacitly allow Seagate DiscWizard for Windows(R) find the target HDD "hands-off" - do not do any searching, but merely confirm its choice if correct; (3) Use DiscWizard to lay out the first NTFS primary active partition as 52GB (by default anything over 35GB transforms to NTFS, so anything over that size is arbitrary - as are the number of NTFS partitions for that matter); then lay out another NTFS partition of 57GB (by default, this second partition becomes the basis of an extended partition); and finally, lay out about 25GB for the last partition which by default will be FAT32 w/16kb cluster so as to leave the remaining freespace unencumbered until subjected to the GROW command during a follow-up pass in SAFE MODE; and (4) Then - and only then - do I go into Partition Magic 8.0 where I CONVERT the leading NTFS primary active partition to a logical drive to share the single extended partition with the 57GB NTFS logical drive and the now GROWN-UP FAT32 logical drive whose volume has expanded from 25GB to 39GB albeit it does retain 16kb clusters. I avoid primary active partitions on all internal SLAVE HDDs and external HDDs as well - particularly those devices with SATA or SATA/USB combo capability where the dread message 'NTLDR is Missing - Press any key to restart' can jump up and bite you if your MASTER HDD has been reassigned from IDE to SATA.

Now, I'm probably going to prove that I'm thick but:
gdisk "diskno" /diskwipe is done to get all space "used", filled with zeros, right? The resizing and merging of partitions is to maintain 16 kB clusters on a FAT32 partition larger than 32 MB, right? If the above is correctly understood, why not use a Win98 or WinME start disk to format and use the commands /U (unconditional, said to wipe and zero fill) and /Z:32 (will yield a cluster size of 32 x 512 bytes = 16 kB). If the drive letter is H: it would be "FORMAT H: /U /Z:32". Christer |

BE ADVISED: DiscWizard assigns file system format by the volume of the partition selected, plus the second partition and all subsequent are going to be in an extended partition as a set of logical drives no matter what you do or don't do - forego fighting any of this early on: (1) The 60GB IBM IDE HDD would be best, but with only two partitions - initially go for a leading primary active NTFS partition trailed by default with an extended partition containing a single FAT32 logical drive; (2) After the so-called "low-level format" with GDisk, use DiscWizard to assign the target HDD as 'Additional Storage' and when underway proceed to slide the scale LEFT-to-RIGHT until the leading partition changes from GREEN-to-PURPLE (FAT32-to-NTFS) at about 36GB and stick with the NTFS default file cluster size as you mark SET; then (3) For the trailing partition, keep an eye on the window below the pie-chart graphic for the shift in FAT32 default cluster size from 8kb-to-16kb as you slide the scale LEFT-to-RIGHT and STOP RIGHT THERE to mark SET and then select the NEXT> radio button (you will find the remainder of this phase to be straightforwardly automated); (4) Upon exiting from DiscWizard, reboot your PC into SAFE MODE and reenter DiscWizard to select the Maintenance radio button to go to 'Maintenance Options', select 'Partitioning and Formatting Options' where you in turn select 'Grow a Partition' (this feature actually pumps up the logical drive to force the extended partition to occupy the remaining freespace albeit while retaining the 16kb cluster size - you will find the remainder of this phase to be likewise straightforwardly automated as DiscWizard will reboot without intervention on your part); (5) After the system reboots, you merely hit the Finish radio button, then in turn the Exit radio button and on to PM8; and (6) Once in Partition Magic 8.0, target the NTFS partition in the lead and perform a 'Convert partition' from Primary-to-Logical - et voila' - you are done. The trick now is to see if there are any marked performance differences between NTFS and FAT32. I am reasonably confident that the IBM HDD will be amenable to the Seagate DiscWizard, but I cannot assure you of this. [glb]El Pescador[/glb] |

I was reading your reply # 134 to Christer. You talk about installing Seagate's DDO (dynamic disk overlay). But your instructions above make no mention of doing that! Also, your reply #134 refers to *DiscWizard Starter Edition*, but in the outline above you refer to *Seagate DiscWizard for Windows*, which appears to be a different program!? Two questions: 1. DDO is for systems that can not recognize the full capacity of larger HDD's because of BIOS limitations--why would you be recommending that on a system whose BIOS recognizes the HDD capacity natively? 2. Does the Seagate Disk Wizard program *automatically* install the DDO on the HDD when you use it to partition the zeroed out HDD by GDISK? ********************************************* Separate question: In another thread here: TYPE FLAGS: A component of USB misbehavior ? you said you were getting an *Error # 91* in DOS PartitionMagic, which stated that it was detecting *Disk Manager*. *DDO* is also known as *Disk Manager* and this may be the source of that error message! Have you attempted to install DDO on all your HDD's? |

Christer - All of that is most likely correct - and exceedingly elegant, I might add - but at the end of the day will your troublesome HDD so configured have its FAT32 partition perform almost as well as its NTFS partition, for that is the real question. All I do know is that my Western Digital SLAVE HDDs configured in time-honored fashion experience Ghost 2003 Backups with NTFS partitions at 1/4-to-1/3 the elapsed time achieved with the FAT32 partitions. After being reconfigured as described above, the FAT32 partitions will almost achieve parity with the NTFS partitions - go figure !!! Regrettably, I cannot explain why it happens - I can only say that I can make it happen in my modest environment. However, if you and NightOwl do in fact independently succeed in replicating my findings then this becomes a whole new ball game, doesn't it? [glb]El Pescador[/glb] |

That has been done by default with DiscWizard all along, but I only recently became aware of it. In fact, I have spent several hours today with a Seagate utility that is supposed to remove DDO - and although the option is visible, it is "greyed-out" so that I cannot invoke it. Since the utility is DOS-based, I am unable to make a screenshot to post. NightOwl wrote on Aug 22nd, 2005 at 11:58pm:
DiscWizard Starter Edition is the DOS-based version that overlaps DiscWizard for Windows to a great extent, but Seagate recommends the Windows version to make a final wrap - particularly where either the HDD exceeds 137GB or the client is running XP w/SP2 - or both. NightOwl wrote on Aug 22nd, 2005 at 11:58pm:
This is not a recommendation one way or the other - it is nothing more than serendiptity that spun off of my resolution of grief with the Iomega External 80GB HDD. I am simply stating that by so configuring I have placed the FAT32 partition of my internal SLAVE HDDs on a performance par with the NTFS partition. It is up to you and Christer to ascertain whether or not it can be replicated with the IBM/Hitachi HDDs. NightOwl wrote on Aug 22nd, 2005 at 11:58pm:
Absolutely and unequivocally - and I can neither stop it nor can I remove it - and I have tried mightily of late to do both. NightOwl wrote on Aug 22nd, 2005 at 11:58pm:
Honestly, I cannot recall either way whether the Iomega was subjected to DiscWizard prior to the attempts with the DOS-based PM8 emergency disks - but damned if doesn't sound likely. NightOwl wrote on Aug 22nd, 2005 at 11:58pm:
I have never installed DDO on any HDD with knowledge aforethought until yesterday afternoon when I was shaking down the process I was outlining for you in Reply #136 on a 160GB Seagate Barracuda IDE HDD mounted in a Metal Gear Box USB 2.0/SATA combo enclosure kit. All of the MASTER HDDs in my three Dell Dimension desktop PCs were classically configured, for I only began using DiscWizard for Windows during the Iomega epiosode. Admittedly, I now have SLAVE HDDs and external HDDs with DDO installed - but I did so unwittingly because I do things heuristically, i.e., I really screw things up, then I go check the manual ...

I looked at the on-line information here: DiscWizard Suite is your installation software kit for installing Seagate disc drives. Clicking on the *Learn More* link just above the *Select Language* radio buttons--according to the *posted* information--only *DiscWizard Starter Edition* mentions the DDO. It implies that it will only install DDO if the program determines that your BIOS does not support the HDD capacity, and it seems to imply that it will alert you that it is installing DDO(or at least has) : Quote:

1. DiscWizard Starter Edition or DiscWizard for Windows--or both? 2. I'm curious--if the option to remove DDO is *greyed out*--how have you determined that DDO is actually being installed and is present on your HDD's? |

In retrospect, I now recall that after completing a very recent GDisk procedure using my Dell Dimension L400c - which lacked the DiscWizard for Windows installation at that time - I rebooted with the Seagate bootable installation CD. I surmise that DiscWizard Starter Edition must be on the "front-end" of the CD, and that must be where I very first encountered the phrase Dynamic Drive Overlay (DDO). NightOwl wrote on Aug 23rd, 2005 at 11:35am:
I did not catch that implication at all, but I cannot argue against it for it sounds quite sensible. When booting from the CD, it advises against prepping the HDD outside of Windows but leads you to believe a DDO will be installed if you so choose. I cannot recall the details in the least, but it seems that a good while back Rad cautioned against drive overlays under certain circumstances. NightOwl wrote on Aug 23rd, 2005 at 11:35am:
The more I follow your assessment, the more I am inclined to believe that the DDO installation is an automated elective procedure - hmm, is that a contradiction within a phrase or not. Let's just say the DDO installation is triggered by a shortcoming of some kind, and if the host BIOS and the candidate HDD are otherwise fully "up-to-specification" and compatible then such will not occur. If I knew how to ascertain the presence of a DDO, I would seek them out in every little nook and cranny of my tangled cybernetic environment. [glb]El Pescador[/glb] P.S.

Title: Re: Comparing HDDs - strange results Post by Christer on Aug 28th, 2005 at 8:43pm
I had time to carry out a few tests, creating and checking images of the source (system) partition, C: on a 120 GB 7K250 with the target partition, F: on a 40 GB 60GXP. Both HDDs are PATAs. The 7K250 also has an extended partition with two logicals. I use No Compression when creating the images. I formated the single partition (all 40 GB) on the 60GXP in different ways and found:
WinME start disk, created extended/logical partition, formated using switch "/u" but let it decide the cluster size (cluster size 32 kB) => create image = 403 MB/min, integrity check = 400 MB/min WinME start disk, created extended/logical partition, formated using switch "/u" and "/z:32" (cluster size 16 kB) => create image = 403 MB/min, integrity check = 392 MB/min WinME start disk, created primary partition, formated using switch "/u" but let it decide the cluster size (cluster size 32 kB) => create image = 404 MB/min, integrity check = 399 MB/min WinME start disk, created primary partition, formated using switch "/u" and "/z:32" (cluster size 16 kB) => create image = 403 MB/min, integrity check = 392 MB/min From within WinXP Disk Manager, created extended/logical partition, formated NTFS with standard cluster size (4 kB) => create image = 854 MB/min, integrity check = 2101 MB/min From within WinXP Disk Manager, created primary partition, formated NTFS with standard cluster size (4 kB) => create image = 854 MB/min, integrity check = 2125 MB/min In no case did extended/logical or primary make a difference. In no case did 32 kB or 16 kB cluster size make a difference (for cases formated FAT32). Under all circumstances was NTFS 2.1 times faster creating and 5.3 times faster checking integrity compared to FAT32. It seems like El_Pescador has discovered something that is quite puzzling. Creating a specific type of partition with a specific (non-standard) cluster size using a specific (quite intricate) method. I used a different method to acchieve similar partitioning but the performance was totally different. I can't predict if I would benefit from the same performance as E_P, if I would adhere to the E_P-procedure on my 60GXP. I don't have access to Partition Magic and have no other incentive to buy it which makes it a no-go for me. Another peculiarity on FAT32 is that Ghost leaves "slack space" between the spans. My images were five spans with four "slack spaces". Any subsequent image gets written in the "slack spaces" of the previous image which makes span #1 fragmented. This doesn't happen on NTFS. Well ...... :-X ...... on my system but I don't know about others! Christer (who from now on, officially believes in ...... :o ...... GREMLINS) |
