One possible cause may be that the MediaMaster's bundled SCSI controller uses the slow ISA bus and the IDE drive connected directly to our system's Enhanced IDE connector. Nevertheless, this is a clear indication that SCSI drives are not always faster than comparable IDE drives. This goes against conventional wisdom, since most users would place both CD devices on the secondary channel. But some IDE hardware and CD mastering software may have trouble using the same IDE channel for reading and writing CDs simultaneously, which can lead to computer lockups and ruined discs.
