I actually found recently I had some documents on an old hard drive that I lost in the process of moving to a new computer in January. But I've done this so far on the drive:
- Formatted to empty
- Installed XP Pro
- Ran Norton Ghost files from OEM to install XP Home
- Installed XP Pro
- Partially installed Caldera Linux (just for fun but it didn't work)
- Ran Norton Ghost files from OEM to install XP Home
- Installed XP Pro to test SP2 RC2
- Ran Norton Ghost files from OEM to install XP Home
- Installed XP Pro to test SP2 Final
- Installed XP MCE
- Installed Longhorn demo - didn't work
- Installed Longhorn demo - worked this time
- Ran Norton Ghost files from OEM to install XP Home to test SP2
- Ran Norton Ghost files from OEM to install XP Home to test SP2... 2nd round
- Installed XP MCE - failed
- Installed XP Tablet PC
- Ran Norton Ghost files from OEM to install XP Home to test SP2... 3rd round
(I test software on different operating systems, actually I've got some stuff to test on windows 2000 so I'll be doing that next when I get a chance)
So there's no way I'd be able to recover anything from that now... It's only a 6 GB hard drive.

I'm going to have to look into that getdataback though... Sounds interesting.
