My Rana Elite Three floppy drive on my Apple ][+ seems to have gone
permanently write-protected.  I think the problem could be in one of
three places (in order of what I think is most likely): 1) the light/
LED and photo-sensitive detector that senses the cutout in each
floppy, 2) the user's write-protect switch (temporarily used instead
of using a sticker to cover the floppy's cutout), or 3) some of the
electronics on the board with the drive.

I took a brief look around inside; nothing was obviously loose or
blown.  The drive mechanism was an MPI 92 (I think that's the number),
a 96 tpi, 80 track double sided model.

Does anyone have any suggestions on easy ways to pinpoint the problem?
Any idea how much a dealer would charge?  I'd hate to pay $50 or more
to replace an LED...

Replies/comments to me, please.
