Several years ago, BTD (before tape drive) I experienced a similar
problem.
During backups to floppy, the system would occasionally panic
or the controller would go crazy returning errors streaming
endlessly off the screen while the floppy drive clicked like
it was making butter.
I was told that certain drive/controller combos exhibited this
problem and one possible solution was to patch the kernal with
the following:
mount -r /dev/fd096 /mnt #mount N1 floppy
cp /mnt/bin/adb /bin/adb #copy general debugger
umount /dev/fd096 #unmount N1
cp /xenix /xenix.good #make copy of xenix
adb -w /xenix #invoke debugger
$x #set input/output to hex
flparam/w 10df #slow floppy load time
$q #exit
Although I changed my controller before I had the chance to
try it, it slows the floppy head load time, which may correct
the problem for some controllers. Changing the controller did
eliminate my problem.
