I would agree with your view on IDE becoming obsolete on hard drives, but I as yet, am not aware of any CD/DVD drives with a SATA interface.

SATA isn't really "new" any more. I personally consider IDE to be
obsolete. Seems to me that Linux should fully support SATA to the same
level as IDE drives. And I'm saying that as someone who doesn't have to
actually code it. But I will leave messages of praise and thanks in this
mailing list if you all catch up.

As Alan mentions in another thread, what is needed is true hotplug support,
which is difficult with some controllers for which we have poor (or no)
documentation. I wouldn't hold your breath.

As for pass-thru standby/sleep commands, as long as the pass-thru patch got
into mainline, try a very recent version of hdparm which should understand
sending the ATA commands over SCSI (libata).
