I am having trouble with my 486 PC machine. I was wondering
if anyone can shed some lights on the matter.

The program is that my two floppy drives (5|1/4 and 3|1/2)
failed *simultaneously* during a machine-to-machine file
transfer done by a friend of mine. My PC since ceased to 
read data from either of the floppy disks--screaming 
'data reading error' for a formated disk and 'general
reading error' for a unformated disk.

The machine, under DOS 3.3, is working as usual on hard
disk. But I can neither read or directly reboot from floppy
drives. I have looked at my CMOS configuration at the
booting point, the disk configurations are correct.

I firmly believe that the problem lies in software or configurations
as I can hardly believe that both drives physically failed at
the same time when no violent physical impact was experienced
by the PC.

If you have any idea or advice on how to locate the problem of 
my PC properly, please give me some suggestions---big or small,
complete or incomplete--all of them will be greatly and
equally appreciated.

Thank you very much for your efforts
