	Using gdisk to wipe a hard drive May 28^th, 2012 at 9:13am Using gdisk to wipe a hard drive For years I have been using gdisk to wipe hard drives I created floppy disk with the batch file. I got gdisk from my original cd of ghost 2003 and use qwipe. It works fine for a PATA – IDE hard drive, but I cannot get it to work with a SATA hard drive. Suggestions please

More info, please.

What error message(s) are you getting, if any? How do you know it's not working?

What size SATA HDD(s) have you tried so far?

Hooked up to the Motherboard--or to a USB adaptor?

What response do you get if you try the gdisk command: gdisk /status ? Does the SATA HDD information show up in the response--or do you get any error messages?

To All--if you did not understand the reference (I know I didn't!):

Hmmmm.....doing a Google search shows some references to using this program--but, no useable links: http://www.google.com/#sclient=psy-ab&hl=en&site=&source=hp&q=dbanuke&btnK=Googl...

But, using this term *dban nuke* brings up a much more meaningful response: http://www.google.com/#hl=en&rlz=1R2GGLL_enUS385&sa=X&psj=1&ei=fdHET4iyAsea2AXcm...

Again, where in the process does the program *fail*?

Thanks for the feedback. A bad drive certainly could cause problems. If you have the time, it would be interesting to know what error message that bad HDD generated for gdisk.

To All

If you want to know more about what *gdisk* can do, here's a couple reference links--it's Ghost's command line partitioning tool that has some other helpful functions as well. *Gdisk* is the DOS based tool, and *gdisk32* works under Windows:

Switches: GDisk and GDisk32 for Norton Ghost 2003

Switches: GDisk

thank you for the references. I have read them and saved them.

yesterday i was trying to wipe a 750 gig sata drive.

I got following display

starting windows 98

A:\>gdisk 1 /del /all /qwipe
GDISK (E) No such fixed disk -- 1

A:\
A:\
A:\

i booted from floppy with the following line in the autoexec.bat file

A:\>gdisk 1 /del /all /qwipe

is there a size limit for gdisk ?

maybe the hard disk is bad.
i will try spinrite and report back.

So, don't try to *automate* gdisk's functions. Just boot to DOS and then type: gdisk /status

See what listing of HDDs shows up.

Why not use */diskwipe* instead of */gwipe*--looks like you could bypass the */del /all* commands with *diskwipe*:

From here: Switches: GDisk

Quote:

GDisk /DISKWIPE /?

This command displays the command-line format for the /DISKWIPE operation. The /DISKWIPE command wipes out all information on the hard disk.

--------------------------------------------------------------------------------

Warning: The /DISKWIPE command wipes out the entire contents of the physical disk. Make sure you specify the correct fixed physical disk before proceeding. You can use the /STATUS command with a disk number to check the identity of the fixed disk that you specify.

Quote:

Maybe, but I would try to determine the correct drive number that Gdisk is using/seeing based on the *gdisk /status* result to see if that command line needs to be changed for some reason.

	Re: Using gdisk to wipe a hard drive Reply #11 - Jul 19^th, 2012 at 8:22am What is your current SATA mode? Perhaps gdisk will only recognise the drive in ATA mode?
