After trying to boot my machine, I get past the XP screen
and my computer just reboots. Then continuously tries to
start up only to reboot. If I try to enter into safe mode
or any other the same thing happens. When I disconnect my
additional hard drive, I can boot with no problems at
all. Also, I can see the drive and even move/copy/delete
files while using Knoppix, just not with XP. Is there
anyway that I can recover this drive?

What I forgot to mention is that it's a Western Digital
120GB Drive. Nearly the entire drive is full of info that
I need. And I don't have enough space on my other drives
to backup the information. Should I delete the CLSID info
on the drive or some system files that I can see that are
at 0kb?
