If your drive is an Atari drive (or basically a plug-in drive you
bought), and you are having problems, then the interface board in that
drive is the problem.

However, if you are building a drive, then the problem is simple.  You
can either:

1) Get TOS 1.4 - it re-opens the disk EVERY time it goes to read it!

2) Run a jumper between pins 2 and 28 on your drive mech.  This
   ties together the WRITE PROTECT and MEDIA CHANGE lines.  Atari
   drives need both signals in one pin.  However, if you get write
   protect warnings when the jumper is in place (like I did with my
   Tandy drive), you are kinda in trouble.  I placed a momentary
   switch (normally open) between the pins, and when I put in a new
   disk, I have to press it so the media change is received.

Hope this helps.
