When I've experienced the problem you described, the cure for me was to
move a jumper on the floppy drive from the "A" to the "B" position.
Look for it on top of the drive, toward the end (away from the drive
opening). You'll find a three pin 90 degree angled connector that may
or may not be labeled with the letters A and B. If its not labeled,
just move the jumper in the second possible position (always covering
two of the three pins). That should take care of your DIR B: problem.
