Sorry. Next time I'll try to explain more slowly. :-)

If those error message won't stop after pulling out the disk you might have to kill
the process still trying or reading from the devide. Perhaps a ^C will work, but
probably you'll have to do a #ps -ax to see what's going on.
One problem might be the different floppy drives. Although this isn't a very
good solution, you might have to throw out the Compaq drive and buy a new
one. I never had trouble with TEAC drives, but SONY drives are *always* calibrated
a bit different.
