No. The SCSI-2 specs contain absolutely no information about reading CD-DA, that's why there's wilderness instead of agreement about the actual implementation and command set used. Moreover, the SCSI-2 specs are braindead enough to explicitly prohibit reading CD-DA with a normal READ command. This intent must be rejected with an ASC/ASCQ of 64/00, ``ILLEGAL MODE FOR THIS TRACK''. So any actual device that can do it is violating SCSI-2, if you take this strictly. -- cheers, J"org joerg_wunsch@uriah.heep.sax.de -- http://www.sax.de/~joerg/ -- NIC: JW11-RIPE Never trust an operating system you don't have sources for. ;-)
