IBM PS/2 Model50 disk drive problem

June 20, 2005 at 09:56:48
Specs: Windows 3.1/Win 95, 486/ 12-16 mgb ram

I have been having problems with an OS2 type disk drive in both my computers, particularly with the one in a windows 3.11 computer. It has stopped reading 1.44mgb dos/windows formated disks. I had been able to use several kinds of disks (formatted from windows 3.11 up to xp), though a it stopped doing so a few months ago. Though it still managed to read a OS/2 disk that I managed to scrounge up Is there a software fix for this? I tried looking for a fix to this problem on IBM's support website with no luck. Is there a way to fit a regular IDE disk drive into the Model 50's pin?

Thanks in advance,

I believe they use proprietary hardware...

Ignore above it has for some reason been removed.

"OS2 type disk drive" WTF

IBM uses IDE Hard Drives and Standadard Floppy Drives, it is the Controller Connection Cards which are proprietary. You will need to find another IBM PC, though what this has to do with W3.x I am at a loss to fathom out

There are 2 possibilities from your

1. The floppy drive is damaged, dirty or
dead. Easy enough to check with a known
good boot disk. If so get a functioning
replacement floppy disk drive from another
computer of the same make and model off of
e-bay for example.

2. The computers bios battery is dead and
it (no longer keeps correct time) once the
computer has been unplugged and then
replugged the time and date are off this
may have caused your computer to forget
that your 1.44meg floppy is a 1.44meg
floppy and think it is a 720k floppy as
I think was its default on that model if
I remember correctly(been a while) you
will have to go into the bios when
starting up your computer and check.

also look onto your working (os2?) floppy
and check if it has one or two holes in it.
if its one hole it is in fact a 720k floppy
disk. this will help confirm if your drive
is set to 720k mode. you can also
make(more) floppys if you can't figure out
how to change the floppy mode back to 1.44m
mode. simply get a new floppy and cover the
hole without the write protect tab and then
reformat it (this will wipe any data off of
the floppy). then it should work from then
on as a 720k floppy which I suppose beats
