The 800k floppy disk drive in one of our Mac II's recently went flaky.
Symptoms:
Disk accessing operations occur abnormally slow. For example, when a disk
is initialized on a healthy drive, you hear the tick..tick..tick as the
read/write head advances from track to track. On the flaky drive this
sounds like tick...............tick..................tick (or even
slower). Launching applications and reading documents is extremely
sluggish. Worst of all, sometimes the drive stalls completely, requiring
an abort and machine reboot.
The Apple-authorized service technicians at our campus computer repair
facility do not fix disk drives, they only pull and replace them. Since
we use this Mac a lot, we have already installed a new drive. But I kept
the broken unit, and I wonder if anyone on the net can give me some tips
on repairing it. So far I have been brazen enough to remove the drive,
clean out all loose dust and grunge, and relubricate parts of the
mechanism that appeared to be originally lubricated. It still does not
work.
If nobody recognizes an obvious fix for the symptoms I described, I would
still appreciate any of the following:
a) pointers on where to get documentation, schematics, service info, or
diagnostic test programs.
b) the names of any shops that do repair work on Sony floppy drives for
less than the cost of replacement drives (about $200 here at Cornell).
Thanks.
