CD/DVD drive are also treated as SCSI drives. You get /dev/scd0 and /dev/sr0 for the first drive, /dev/scd1 and /dev/sr1 for the second, etc. This is regardless of them being PATA, SATA, or a SCSI drive. SCSI CD/DVD drives have always used /dev/scdx.The kernel treats all block-replaceable storage (hard drives, ZIP drives, FLASH drives--basically everything except floppies and CD/DVD drives) as though they're SCSI (regardless of their physical connections).
Tape drives are /dev/stx and /dev/nstx - each drive has both devices. (SCSI tape and Non-rewinding SCSI Tape)Old kernels separated PATA/IDE drives from SCSI with the "hd" in /dev/hd* names meaning "hard disk" (PATA/IDE) and "sd" meaning "scsi disk". With new kernels, you won't see "/dev/hd*" names any longer, so it may be easier for you to think of the "sd" in /dev/sdXY device names as "storage device" from here on in.
One thing I have not looked at - are the special CD interfaces still handled the same, or are they SCSI devices now? (The ones that attach to sound cards, or their own special controller.) I suspect they still have their old names, because they were not IDE or SCSI drives.
