I have a couple of floppy drives on 68K Macs that are pretty well dead. They spin, but seem to have trouble with advancing the head and especially with ejecting disks(although I can eject manually fine). From what I've read/understand these drives probably need to be disassembled, cleaned, and regreased. All that I have are 1.44mb "Superdrives" and are the auto-inject kind. I am a watchmaker so have no issues dealing with small parts and fiddly operations, but also don't want to tear into these without some sort of guide as to what to do/what not to do. I've tried Google, but it has failed me on this task. Can anyone point me to an online guide with a tear-down or just general instructions on how to rebuild one of these drives? Thanks in advance.
