According to Leo, this is often the sign of a virus. Audie thought so too, and decided to format his hard drive and start over, but it won't format. Leo says that there must be flaws on the drive causing this, and they could be in the master boot record or another non destructible sector. He may be able to switch it out with a replacement drive - they're not that expensive. If it's not replaceable, then a recovery utility like SpinRite may be his only solution.
