Ok, I tried about 10 times but the results are the same.  I tried mounting
the CD on several occasions between re-inserting the media and was able to
mount it every time.  Of course I allowed for at least 30 secs to settle
down between removals, re-inserts, mounts and burncds.

Doesn't the "ILLEGAL REQUEST" mean that a certain command is not
understood by the hardware at all?
