Apple 3.5 drive woes

[viking@iastate.edu (Dan Sorenson)]

	Here's a strange one.  I loaned a 3.5" drive to a friend of
mine, keeping the other for myself.  He returned it, I attached it
(yes, I powered down the machine and waited), and it worked fine.

	The next day, neither drive will read a disk from GS/OS,
and only occassionally from Prodos 8.  In addition, every format
fails and reading is very spotty on a file-by-file basis.  The
format in Copy II Plus gives the error at block 0006, if that's
any help.

	Thus, the question: anybody know of a place that repairs
Apple 3.5" drives for a reasonable cost?  Apple dealers just like
to replace them, and I see no reason to pay $75 each to exchange
them with some place.  There has to be some place that will replace
drive heads, or set alignment, or whatever is wrong on a part-by-
part basis, or at least quite cheaply.

	Ideas?  A phone number is great to include.
