So I have 5 hard drives, 2 80 Gig Western Digitals, 2 80 Gig Seagates, and 1 30 gig Maxtor. They all have the same problem, when doing intensive read/write, the harddrive will make a single *clunk* then the computer will restart, as the computer restarts, you can hear the hard drive spin back up. This is on 2 DIFFERENT computers both running windows XP, Ive tried 5 or so different IDE cables, switched drives from computer to computer and im still having problems. In the windows Event viewer, I get a strange error. I will post exacly what it says as soon as I get home ~5:30 central. When I look at the Solution to the problem that microsoft provides, it says "This problem is caused by a failing Cable, install new cables to fix" This is the strangest problem Ive ever had w/ a computer.
