I have experienced similar problems with disk caching softwaer and programs
compiled by the clipper.  After a bit of use it corupts the indicies.

Have been running several different boards in this old PC.  Used to be a
dual drive floopy unit with one single and one double sided drive.  None
seem to have caused it any problems.  Maybe the card is actually defective?

Running an ST-225 on this thing with 1:4 interleave.  I settled on this
interleave factor after running performance benchmarks with 1:5 and 1:3.
This one yielded the best results.  Even using the turbo board may not call
for 1:3.
