After rebooting my os/2 ccmail server (which was working fine for many
months and without installing any new s/w or update) produced the message
"OS/2 is unable to operate your hard disk or diskette drive. The system is
stopped.
I have tried booting from flo[ppy disk and then running CHKDSK, I also
replaced my config.sys from another copy but that didn't help either.
Can anybody please help?
Thanks to all in advance for your help.

Christos:
The last time I ran into this problem, it was the hard disk drivers
that were giving me trouble (I had replaced the IBM1S506.ADD with
TRIOS2.ADD, a driver designed 'specially for the fast I/O on my
motherboard.') OS/2 didn't like that at all...at least, not the version
I was using.
If you've changed the floppy (IBM1FLPY, IBM2FLPY) or hard disk drivers
(IBM1S506, IBMINT13 for IDE, SCSI is different), you may need to copy
the driver from your latest backup or the original distribution. Your
problem lies somewhere in those disk drivers.

Cheers,
Chris

Something changed. It is hard to tell what, given the little you
provide.

Generally you get the above message when something has changed in the
partitioning of your disk. OS/2 begins booting with BIOS calls.
From the way it is started, it makes some determination as to whether
the boot partition is C: or D: or whatever. At some time it switches
over to the run time disk driver. At that time it finds out what
disks partitions are available to it. If what it originally took to
be C: is not really C:, for example, you will get the above error.

You don't say whether you are booting from BootManager, or by some
other method. You need to look into which partitions are hidden,
what OS/2 thinks the partition lettering is, and what about this
might have changed since you last successfully ran your system.

Check your BIOS Setup for your HDD. It may hve dropped the LBA
translation for your drive or enabled it if you weren't using LBA mode
before.

If at first you don't succeed, destroy all evidence that you tried.
