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. ------------------------------------------------------------------------------- The DiskDoctor threatens the crew!
