I have a strange problem with XP. Every few days it loses a file, gives me a bad checksum message or this morning, I had to run repair. Also, on my sound card or actually the software seems to get lost if I don't play it for 2 or 3 days and I have to reinstall the program. I have run checkdisk and defrag and ran Maxtor's utility. I haven't done a low level check yet, as I really don't want to reinstall everything. It acts like a bad sector on the drive, (40GB Maxtor), 2 yrs old. But I would think it would show up on checkdisk. I was going to get a new sound card, but I don't think that is the problem, as when I play a CD every night while I'm working, it does fine. Maybe it is like me and getting old and senile. Any ideas appreciated.
