To get the drive to acknowledge a media change, run a jumper from pin 2
to pin 28 on the drive's 34 pin connector.  As you look at the mech from
the REAR, pin 2 is the top left pin, 28 is the 4th pin from the right.

Atari's drives combine media change (pin 2) and write protect (pin 28)
into one pin.  This is why you can't get a media change without this
jumper.

However, be sure and try to write to the disk after you do this.  If the
computer gives a constant "Disk write protected" warning, then
disconnect the jumper.  I have this problem.  My Teac mechanism doesn't
have a strong enough write protect signal to make it with the two wires
connected.  However, I doubt you will have this problem.
