It sounds to me like you've told the system that the hard drive is a
little bigger than it actually is. I've had no problem at all when one of
my 70 meg partitions was 100% full, either on the Hardframe on the
2000/2500 or on the A3000 controller.

For a simple test of your drive, get Fred Fish's FillDisk program (on
one of the older disks), and run it on your hard drive. FillDisk simply
opens a file, and starts writing to it until the disk fills up. Fred
intended it to clobber any deleted files that you might not want someone
else undeleting, but it does make a handy disk tester.

If FillDisk starts reporting I/O errors at 97% full, I'd suggest backing
up your drive, reformatting it with a few fewer cylinders, and running
FillDisk again. If you get no errors the second time, you've found the
problem.

This worked fine for me when I wanted to verify that the fake floppies
I'd created by juggling mountlist entries did not overlap any other
partitions.
