Ultimate Boot CD

I'm trying to view what's on i believe a linux drive. if i plug in as a secondary hard drive xp can't see the drive (not in disk management) but the bios see the drive.
I was able to use HD Clone and clone the drive. so I tried used UBCD to view files on the drive but when I boot from the CD i get
Error Reading Main Disk a few times and then at the bottom it says
Security Error Code 1

Any idea's?

Try booting to a Live Linux Cd like Knoppix or some newer distro > http://distrowatch.serve-you.net/ <. You'll be able to see the drive in a native linux environment and you could use GParted or other partitioning software to clear the partition/drive if needed. You should be able to run some other partitioning tools as well and they would show the drive/partiation as a NON-DOS disk/partiation - just delete it and put a new partition in it's place...
