Same here! The failure was detected at the BIOS level.

My cable was an ATA 66 MHz ribbon cable.

The drive burns CDROMs reliably. Other than the problem with the Slave
jumper setting still letting the drive assume master. I wouldn't trash
it just because it wants to be Master. (Unless jumpered as CS)

I found information regarding how pin 28 is grounded for master using CS
and not connected for slave to be the interesting aspect. The
information on old 40-pin cables vs. newer ATA 66 or higher MHz to have
pin-28 disconnected in the middle (secondary position) interesting with
the system connector and master connector at the ends.
