Re: Platinum 5.25" drive problem

No, the stepper motor does not control the drive speed, it moves the heads
in and out. Of course I am assuming the stepper is moving the heads. This is
normally something you can hear if you put your ear up to the drive, or open
it up and see what it's doing when reading the disk.

I would open it to get a few more clues.
