Now that I'm looking squarely at the issue, I have not been able to
reproduce it yet!
When I was dealing with it earlier, I was experiencing (as I wrote in
the bug report), that the error ALWAYS occurred when I had unformatted
D: and E: partitions, and when I formatted those, the problem seemed to
go away at the time, though this was not rigorously tested. Then it
recurred, and I filed the bug.
Tonight, aiming for a repeatable test, I installed FreeDOS on another
drive with unformatted D: and E: partitions, but the format error did
not appear in some quick testing.
Next, I grabbed one much-recently-used-known-good floppy, and 4 others
with content on them, but which had been sitting in a box for a long time.
Then I ran a series of format tests on them. Not once did I did get the
error of interest, but I was getting a lot of bad sectors reported.
Results:
Disk #1
FD with unformatted partitions on PC #1, using FD format: 11 bad sectors
W98 on PC #2, using FD format: 0 bad sectors
W98 on PC #2, using Win format (via GUI): 0 bad sectors
W98 on PC #1, using Win format (via GUI): 0 bad sectors
W98 on PC #1, using FD format: 0 bad sectors
FD with no unformatted partitions on PC #1, using FD format: 0 bad sectors

FD with unformatted partitions on PC #1, using FD format: 15 bad sectors
W98 on PC #2, using FD format: 1 bad sectors
W98 on PC #2, using Win format (via GUI): 0 bad sectors
W98 on PC #1, using Win format (via GUI): 0 bad sectors

W98 on PC #2, using FD format: 51 bad sectors
W98 on PC #2, using Win format (via GUI): 144 bad sectors
W98 on PC #1, using Win format (via GUI): 180 bad sectors
W98 on PC #1, using FD format: 4 bad sectors
FD with no unformatted partitions on PC #1, using FD format: 0 bad sectors

W98 on PC #1, using FD format: 0 bad sectors
FD with no unformatted partitions on PC #1, using FD format: 0 bad sectors
Disk #5 (the known-good disk)
FD with unformatted partitions on PC #1, using FD format: 0 bad sectors
W98 on PC #2, using FD format: 0 bad sectors
W98 on PC #2, using Win format (via GUI): 0 bad sectors
W98 on PC #1, using Win format (via GUI): 0 bad sectors
W98 on PC #1, using FD format: 0 bad sectors
FD with no unformatted partitions on PC #1, using FD format: 0 bad sectors
So though I failed to duplicate the error of interest, what I seemed to
show is that floppies that have been unused for a long time will report
bad sectors initially, but that under use they will loosen up and become
more reliable.
An interesting result, but not very helpful for the error of interest.

Does it work on the w98 computer with freedos version of format? I am
trying to see if it is format, kernel, or both causing the issue.
Thank you,
