Re: Fixing flakey floppies

I have also encountered many drives in which the grease inside the hub spindle and/or hub clamp bearings had dried out. When I am cleaning up a new-to-me old floppy drives, I check all of the ball bearings in the spindle and hub clamp to make sure that they spin freely. If they drag noticeably,
