Moved a big (120gig) IDE hd from one computer to another. Second computer dies (or won't start) as soon as it's plugged in - display disappears if running, no display at all if starting up, other HD makes 'clunking' noises(!), etc. Problem also appears if new HD is the ONLY thing plugged in. RMA'ed the HD; new one does the same thing - plugging it in turns it into a boat anchor. 'Puter runs fine without it.
Computer is a PIII / 600 MHz and thus old. But older computer runs HD fine.
