Apple 3.5 Drive External Floppy Drive Teardown
Tools
These are some common tools used to work on this device. You might not need every tool for every procedure.
This drive can be upgraded to be a SuperDrive/FDHD drive to be able to read/write High Density floppies by changing out the Double Density drive mechanism for the Sony 2.0MB High Density Auto-injection floppy drive mechanism. It is generally easier to find this mechanism as pulled from a parted out Macintosh than to try to find a complete orginal external SuperDrive/FDHD unit.
