Thanks for that suggestion.  So I tried a different tape (even a tape by a
different manufacturer) and I encountered the same problem.  I also tried
(following another suggestion made to me) running a head cleaning tape through
the drive before I tested the other tape.

(I did forget to mention in my original message that this is a brand new tape
drive (well, a couple of months old, but it's been sitting unused up until this
point) and these are brand new (unused) tapes).

Is it at all possible that there could be bugs in the ahc driver when running
on a aic7899 controller that might cause it to mis-interpret what the hardware
is telling it?  Or is the code that reports error conditions so simple that
"it must be correct"...?
