Try changing the jumper from DC to RDY.  On the IBM-compatible Toshiba drives
I have, the DISKCHANGE signal is jumper-selectable to appear on the RDY
signal line instead of its usual place (on pin 11, I think.)  It appears
that changing the jumper might move the RDY and DISKCHANGE signals back to
where the Amiga expects them.
