I lied. Opened up the drive again because it once more stopped working.
Removed the stepper motor and *oops* the top two bolts were held in using washers and bolts INSIDE THE DRIVE! Eek. So I had to remove the cover and fish them out, then put them back in place.
The inner bearing of the stepper motor received a couple of drops of oil and it finally got rid of the crunchiness you could feel when turning by hand. Since I had the drive open, I put the smallest amount of oil on the shaft.
It's all back together now and passes the self test 100% of the time. Won't boot - but whatever, that's nothing new! Still gives me a happy mac. It isn't a great idea to open drives. |

It isn't a great idea to open drives. I know - I had no intention of opening the drive. Unfortunately whoever designed the drive decided to have a washer and nut inside the drive which falls loose when you remove the stepper motor. If I knew that was going to happen, I would have just added more and more oil to the outside bearing in the hope it would eventually reach the other side.
edit: When I previously said I opened the drive once more, what I meant was, I opened the drive enclosure. This is the first hard drive I've removed the cover from to expose the innards. |

Alright! Troubleshooting progressing!
Floppy Emu arrived. It does the same thing as the floppy drive and hard drive when trying to boot - Happy Mac then back to X. Still won't boot.
I got an error on one attempt that gave Sad Mac 0F0002.
This is after replacing the old 1MB of RAM with 4MB from Mac Memories on eBay. I'm *assuming* the RAM is OK.
What can I try fixing next? |

What can I try fixing next? Well I jumped the gun on that one. I was using the default emulation mode. I've changed the firmware and booted in to 6.0.8 from the HD20 emulator. Huzzah! |
