You can have both /dev/scd0 and /dev/hdd if you are using hdd=scsi. If
you are using hdd=ide-scsi you do not have /dev/hdd anymore (because it
effectively means to use ide-scsi driver so IDE layer does not see this
drive at all).
Pixel, should we default to hdX=scsi for SCSI emulation? Else it is
really bad for those who need hdparm-tune there bad burners.
