By the way I'm running Win XP
I have a Hard Drive, it's no less than 2 years old, and it randomly turns off then back on without warning. And of course when this happens everything locks up.
The Computer itself has a secondary hard drive, it's new and i've never had a problem, and this information is kind of irrelevant because regardless of it being installed or not, the other hard drive still turns itself off and on.
I fixed the problem once before but I recently had to reformat my computer and I did not keep a copy of the program I used to fix it.
Any ideas?
