Generally speaking those in <em>The FreeBSD Project</em> prefer SCSI
CDROM drives over IDE CDROM drives. However not all SCSI CDROM drives
are equal. Some feel the quality of some SCSI CDROM drives have been
deteriorating to that of IDE CDROM drives. Toshiba used to be the
favored stand-by, but many on the SCSI mailing list have found
displeasure with the 12x speed XM-5701TA as its volume (when playing
audio CDROMs) is not controlable by the various audio player software.
Another area where SCSI CDROM manufactors are cutting corners is
adhearance to the
<ref id="scsi:further-reading" name="SCSI specification">. Many SCSI
CDROMs will repsond to
<ref id="scsi:rogue-devices" name="multiple LUNs"> for its target address.
Known violators include the 6x Teac CD-56S 1.0D.

Although the SCSI standard tries to be complete and concise, it is
a complex standard and implementing things correctly is no easy task.
