  A lot of the older SGIs and Suns required that the CD drive DEFAULT to
512 bytes/block or else they won't work. The newer systems issue a SCSI
command to the drive to set it to 512 bytes/block but the older ones didn't
issue the command and if the drive didn't default to that then you wouldn't
work. On some drives like the Toshiba 3401s you could change the jumpers
to control the number of bytes/block that it defaulted to. Just a quess
but I could be completely wrong.
