Where's the XP Installer's Undo?

A Windows 2000 hard disk got clobbered by the XP installer and is "unallocated". What are my next steps?

I have an old PC running Windows 2000 (SP 4). There are 3 internal drives:
D: 40 GB (Win2K system disk)
C: 200 GB
F: 500 GB
Recently, I tried to install WinXP on the C drive so I could dual-boot Win2K and XP. I ran the XP installer (new install, not upgrade); it successfully completed but I could never boot from C; it was giving me various errors about missing hal.dll and stuff. I've basically given up on the dual boot on this machine; I don't need it badly enough to spend more time on it.
After my first attempt to install XP, I discovered Win2K no longer mounts the F drive. It still shows up in the BIOS, but not in Windows Explorer; only the C and D drives show up in the Explorer address bar now.
When I go into Computer Management, I can see the missing drive in the Disk List and Graphical View, but not in the Volume List. In the Graphical View, it shows up as
[no letter drive here]
As far as I can tell from Googling around, the F drive apparently had EZ-Drive on it (I tried Partition Magic 6, and it gave me an error saying "EZ-Drive has been detected on drive 0, but EZ-Drive is corrupt. Run the EZ-Drive setup diskette to correct this problem."), and apparently XP hates EZ-Drive.
I've tried running
(that's the device that shows up using Recovery Console's map command) from the Recovery Console, but it didn't change anything.
The Add/Remove Hardware Wizard can see the drive, too (it says the device is working properly).
I ran Western Digital Data Lifeguard Diagnostics on the drive - did the Quick Test - and got
Test completed successfully
The drive shows up in the Physical Drive list in WD Diagnostics, but not the Logical Drive list.
I'd like to just undo whatever the XP installer did to the drive and get it back to where I can read and use it again. If I have to partition it, I can do that, but I'm wondering whether EZ-Drive will remain on the disk (it sounded like that would happen, based on some of the reading I've done) and what effect that would have on anything else I need to do in the future.
I only use this machine for a couple of pieces of software and I'd like to spend as little time as I can getting it working again. If at all possible, I'd love to avoid reformatting/repartitioning the drive. It just seems like there should be SOME way to undo whatever the XP installer did.
