I believe Ray might be on the right track with the cable mention. I'm fuzzy, but wasn't there a situation where you needed to cut one wire to get an 800k floppy to work in a system that originally had a 400k drive? I can look at my Pina book if I need to at home tonight.

Another check is to make sure that you have pin 1 of the cable connector connected to pin 1 of the floppy.
