I purchased a M0131 800K external floppy drive from ebay and received it today. In the auction description it states that the drive reads and writes fine, but that the electronic eject mechanism is not functioning. Now that I have it, it seems like the whole mechanism is stuck down like there is a disc inserted, but there isn't, as far as I can tell. I hooked it up to my Macintosh Plus, and booted it up with a disk in it's drive, not the external drive. The Macintosh Plus seems to think there is a disk in the drive, because I get a "Disk is unreadable by this computer" message. I can't even get a floppy into the external drive, since the mechanism seems to be stuck down. What could be causing this? Is it fixable? If I use the emergency eject hole, the mechanism comes up, but goes back down again.
