Re: Repairing an Apple 5.25" Drive (A9M0107)

yes it sounds normal but all the tests give speed far too high (above the normal 299) and even if I turn the screw the value doesn't change enough.
when I turn the screw I can hear that the motor speeds up or slows down but the value never gets close to 299
