Hi all,

My 4865 drive has started acting up It won't read anything whatsoever any more, or write for that matter. It used to work fine connected in the same setup as it is now, but it hasn't been used for a couple of years.
The floppys I'm testing with are working fine in a different drive so bad media is probably not the issue.

Symptoms:
Light goes on when I try to access it, and it spins up.
Head doesn't move - probably because it already is where it wants to be, if I manually move it out a bit and then try to access it it does move back when accessing.
When I try to access it I get "Drive not ready".

As a quick hack I added a piece of electrical tape so the media sensor/button gets pushed down a little bit more.
Now when I try to access it I get either "General Failure" when trying to read, or "Invalid Media or Track 0 Bad - Disk Unusable" when I try to format it.

I cleaned the heads, but that's about as far as my diagnostic skills go.
Any tips on how to proceed? I really want to get it working again!
