I have a 2 year old Maxtor 10gig hard drive running Windows 98 installed almost 2 years ago on an ABit BX6r2 mobo w/PII 400cpu. Lately I've had a recurring problem. If I leave the computer for a while and come back there is a blue screen that says "Error writing Drive C" then it usually locks up. When I reboot it says "MASTER BOOT RECORD FAILURE" or something close to that. Then if I shut it off and reboot again all is fine. It's done this 3 or 4 times in the last week. I did a thorough scandisk and it found no bad sectors. I ran a virus scanner and there is no known viruses either. This one has me stumped......
