I can not reformat my hard drive. I have a 486 DX2 66mhz with 16 mg. I loaded Win95, and it locked the computer up. I reformated with MS-DOS reloaded Win 3.1 and it will not read any drive. I have to boot with a system disk, and when I try to reformat with MSDOS disk "1" it gives me a disk error message. When I reboot with the system disk to get a: prompt, it gives me an error and gives the retry, abort, ignore message. WHAT CAN I DO?
