I have 2 HD both Fujitsu 40 G. The system wouldn't boot. It would get to a point in the boot and shut itself down. I loaded the start-up disk and went to FDISK. FDISK shows the C drive as being FAT-16 1 partition only and 2047 MB (10% usage). I took the drives out and change the slave to the master, and omitted the original C drive from the system. Booted from the start-up disk went to FDISK and the partition info showed the same thing for the 1 partition. FAT-16 Active 2047 MB (10% usage). Virus? Thanks in advance.
