I would suggest checking the drive cable. Make sure it doesn't have any obvious defects. If it doesn't, it may be the IDE controller. I'm assuming that this machine is no longer under AppleCare, and that you've done a format and re-install, thus eliminating a software issue. If you have an Apple Service Provider in your area, it might be worth your while to have them do some hardware diagnostics.
