I found this:

WD Lifeguard

Maybe you told Lifeguard to only create a 130 gb partition.

Anyway, to start over (assuming there is nothing you want to keep on the drive)
My Computer
right click
manage
Disk Management
Maximize the window

You can select/highlight the SATA drive, then right click for options.  I would delete any partitions on the drive, then create one large NTFS partition that is 250gb (assuming that is your intent), and then have XP do quick format.

Caution:  be certain you are highlighting the correct one!  If you erase the wrong one, its tooooooo late!

I think that WD created a 130 gb partition, leaving 120 gb unused and unseen.  You'll be able to verify that in Disk Management under XP.

mackey,

Let me know what you think of the Vantec enclosure. It works fine in USB mode but I had trouble in SATA mode.

Mackey,
I hate to see you give up, but I'm glad you narrowed it down.

Which HP D530 do you have and do you know the bios version you have (it momentarily should appear when you boot)?

I found 3 different ones listed at HP support:

HP Compaq d530 Convertible Minitower Desktop PC
HP Compaq d530 Small Form Factor Desktop PC
HP Compaq d530 Ultra-slim Desktop Desktop PC

Maybe you just had trouble with the bios update utility or selected the wrong bios update version.

786B BIOS Family Processor Microcode Update version 1.09 A   (11 Nov 05)

Business Desktops BIOS Utilities version 3.00 A   (15 Jun 05)

I could be wrong, but looks to me like you would need the Bios update utility.  It lists the models supported.  Then download the bios update, and use the utility to install it.  

I just ran a test download of the Utilities. It is supposed to be put on a diskette and then run from a DOS boot diskette.  

If you download the
786B BIOS Family Processor Microcode Update
version 1.09 A   (11 Nov 05)

it will download it to a directory on your c: drive.  When you run the setup/program, it asks you to put a diskette in your a: drive.  I did that and then afterwards looked at the contents of the diskette.  It is a self booting DOS diskette containing the program and bios update both.  After completing the copy of the files to the diskette, you would shut down, and then boot from diskette and it looks like it automatically invokes the bios update program with the 109 update.

Before doing anything though, I would power off your pc, and then watch the startup/poweron and see what version of the bios you have now.  You might have to enter bios setup (F2 or F11 or some similar key), to verify you have 1.08 or older version.

Then be sure you are set to boot from diskette first, and insert the diskette.

After all that, see if your SATA drive works!

Mackey,

I looked at the folder that the setup created, and it is name SWSETUP.  A subfolder of that is a folder called SP31629, which contains the readme etc. files.  There is a bat file there called UCODE.BAT and that is the file you would double-click with Windows Explorer or run.

Did you verify the bios version you have now?  Besides the F2 etc, sometimes if you hit the Pause/Break during boot, it will pause so you can also read the bios level.

John

Mackey, it's not your fault.  As I remember when I first ran the setup it did the unzip and then invoked the program to create the boot diskette.  But at this point from looking at the bat file closer and other files there, you can directly run the UCODE.BAT and that will create a diskette.  You then shut down and restart from the boot diskette to update your bios.

We all have our fingers crossed that this will make your pc properly recognize the large SATA drive size.
