Used to be able to get the floppy drive head cleaning disk that you would wet with head cleaner. With floppy drives disappearing from computers I don't know how available these are any more. Is the drive seeming to misread data or are you just feeling it's a good maintenance thing to do?
On some disks I'm starting to get alot of "DRIVE NOT READY" or "DATA ERROR". I wanted to be able to clean it first before ruling out that it'/s starting to fry on me.
