Mac SE FDHD floppy drive constant buzzing
Posted by: hitherescotty on 2022-06-28 04:43:57
Hi folks.

I reassembled my SE after retr0brighting it and noticed the 2mb floppy drive wasn’t accepting disks or ejecting properly. A disk got stuck on the way out. I could hear it making normal drive noises though. I realized I had not installed it 100% correctly and it was sitting a bit high. I reseated it, hooked everything up and it then just did NOTHING. No sound, nothing. I assumed I’d connected the ribbon cable poorly. Disconnected and reconnected and now it’s just buzzing non stop and doing nothing useful. Won’t read or write or eject. Nothing I do stops the buzzing. I have tried manually ejecting, reseating cable, etc. many many times.

I removed the drive from its mounting bracket and examined while on to see the buzzing is coming from the Omron eject motor. But I cannot figure out what to do. Ideas?

I have twice damaged floppy drives on other machines while trying to clean them. Don’t want that to happen here … I am considering just ordering a replacement on eBay.

Maybe someone who knows better can chime in, but it sounds to me like maybe the main drive gear stripped out, which is a very common problem. New replacements exist, and can be installed relatively easily.

@maceffects sells replacement eject gears. Ones made in Japan that work very well.

Third on broken gear. The originals are made to break. The replacements, not so much... But oh well.

In this video you can see the gear (around 20 min).
