RJARRRPCGP and Jeremy... piece of advice, diagnose before assuming. You both make hasty assumptions to blame hardware without any diagnosis whatsoever. RJARRRPCGP, you can't blame everything on leaking capacitors. Jeremy, there's a multitude of things which can lead to data corruption, the hard drive could be the least defective part. The motherboard, processor, memory, optical drive, drive cables and power supply can all play a part in data corruption even if the hard drive is in fact okay. There's a number of ways to do quick testing to eliminate most hardware issues which can then point to a more definitive conclusion as to the actual problem.
