Boot the hard drive up on a HD diagnostics disk, such as
SpinRite by Gibson Research Corporation (www.grc.com) and
test the drive for physical integrity. This is probably a
very old drive, on a definitely very old machine. Your drive
had a MTBF (Mean Time Between Failures) of less than 5 years of
continuous operation, and you have likely tripled that time.

I'm running a 386/25 with Dos 6.2 for billing. Recently it has been
having problems with bad sectors on the drive showing, and refusing to
boot unless you boot off a floppy and do a sys c: from the A drive.
Now it will not boot from the hard drive at all. Luckily I copied my
customer files before this happened. But there is alot of other stuff
I would like to get off it. To rule out a virus problem is there an up
to date scan program I can get that will run from a floppy on a Dos
machine? Thanks, Lenny Stein, Barlen Electronics.
