Known Issues

Symptom or Problem Encountered

Causes

  • Very common for the plastic supports that hold the head rail in place to break off. This can easily lead to catastrophic damage to the drive head if a user attempts to forcibly eject a disk after this has occurred.

Solutions

Disassembly Notes

(Once drive is removed from Canon Cat)

Do not attempt to remove the floppy cable from the drive circuit board.

Remove small Philips head screws, two on each side, to free both parts of the metal enclosure.
