Well, I've got good news and bad news.

Good news: I got it open, lubed the drives, and its working beautifully! No more buzzing noise. Except:

Bad news: The eject motor will engage and start, but the floppy won't move. I have to use a paperclip to get it up and out. I will post a YouTube video of it to show everyone.

I was wondering, can I move the guts of the external floppy drive into the 512kE? Its the later 800k that is ejected from the software and has no buttons or lights.
