I'm confused a little about the floppy drive in my A3000D. The one I've been using all this time is a Chinon FB-357A which is a HD floppy drive. It hasn't been working very reliably though, and thought I would use the floppy drive in my spare, which I found out is a Chinon FB-354 880k type. But it doesn't seem to work. Inserting a disk will just get "uninitialized" no matter what disk you insert. The jumper is set on the two lower right pins.
All this time, I thought that the FB-357A was an 880k since it never gave me the choice of formating at 1.44. How in heck do you turn on that feature? Also, how do you prevent it from randomly spinning while there's a disk in the drive? I tried cleaning it, and depressing the detection pins a few times, but that didn't work.
