Reviewing the bus trace logs of a test application I see a close track
for an empty invisible track on CD-RW been failed by the drive with
05h/24h/00h (Illegal request - Invalid field in CDB). I agree closing an
empty invisible track does not make much sense, however MMC 5 r03a says
"If this is the incomplete track, the Drive shall pad with all zero user
data to the minimum length of 4 seconds. No other padding shall be
done." Which does not seem to allow the drive to fail the command.
