/dev/sg0 is a generics SCSI device, the one used by burning software to
access the writing capabilities of your CD burner drive, using the
ide-scsi layer driver. /dev/scd0 is the SCSI device used for CD-ROM
accessing. What you experienced is how the ide-scsi module works. The
kernel 2.6 does not need it any more. To find more about SCSI and SCSI
generics please read
