So anyway, I have three old-skool Sony/Apple floppy drives, two 800k and one SuperDrive (and no, it doesn't burn DVDs), each with their own problem:
The MFD 51W-10 looks mechanically ok, disks insert/eject ok, but when you insert a disk, the top read-write head doesn't go all the way down. Also, one thing I've noticed, is that there's a small PCB with some wires and a couple of resistors next to the OMRON R2DG-31 motor that isn't secure - what is this meant to be secured to, and how can I fix it?
The MFD-51W-03 has a mechanical problem...when you insert a disk, the bottom part that normally comes forward, that has the eject handle on it doesn't move, and this prevents you from inserting the disk. All the springs look ok, they look identical to that on the other drives, but for some reason that bottom part of the drive doesn't seem to want to move
The MFD-75W-01G SuperDrive has a mechanical problem also - the bottom bit does come forward a bit, but not far enough, and therefore the disk doesn't go all the way down. The top R/W head doesn't move an inch.
Are any of these drives salvageable, and if so, how can I fix them?
Thanks in advance
