Don't know why your floppy diskette is stuck. But, I can tell you I've taken
appart a Mac II floppy diskette drive which wouldn't load or unload and gotten
it to work. It was a bit of a delicate repair (small screws). The problem
was that the gears/cam on the stepping motor were 90 degrees out of phase.
Once I got them back in phase (and got everything together correctly) it
worked fine.

You'd better like working on fine mechanisms before undertaking this and
you'd better be prepared to scrap the drive if it doesn't work out (could
easily ruin it beyond the shop's tolerance for repairs).
