Note: Adresses reported with dev=ATA are to be used with prefix "ATA:".
Like "ATA:2,2,0" . Their numbers are not cdrecord compatible. See
"Pseudo-SCSI Adresses". It is well possible to use IDE device file
paths like "/dev/hdc" rather than "ATA:2,2,0".
With SCSI devices it is possible to use "/dev/sg1" or "/dev/scd0".
Note: Address numbers have changed since cdrskin-0.2.2. To get the old number
scheme, use option --old_pseudo_scsi_adr . Sorry for any inconvenience.
Note: Adresses reported with dev=ATA are to be used with prefix "ATA:". You may
well use device file addresses as reported with --devices. Examples:
dev=1,1,0 dev=ATA:1,0,0 dev=/dev/hdc dev=/dev/sg1
See also "Drive Addressing".
Note: Address numbers have changed since cdrskin-0.2.2 in order to become

I have the hope that Joerg feels more flattered than annoyed by cdrskin.
Drive Addressing
Drives get addressed either via their cdrecord-style addresses as listed
with option -scanbus (see below "Pseudo-SCSI Adresses") or via the paths
of device files.
Not only device files listed by --devices may be used but also device files
which via their major,minor numbers point to the same device driver as
a listed device file.
Helpful with Linux kernel 2.4 is a special SCSI feature:
It is possible to address a scsi(-emulated) drive via associated device files
which are not listed by option --devices but point to the same SCSI addresses
as listed device files. This addressing via e.g. /dev/sr0 or /dev/scd1 is
compatible with generic read programs like dd and with write program growisofs.
Pseudo-SCSI Adresses
cdrecord and cdrskin share the syntax of addresses but not necessarily
cdrecord and cdrskin share the syntax of SCSI addresses but not necessarily
the meaning of the components. A cdrecord-style address for cdrskin
[prefix:]scsibus,target,lun
can be interpreted in two different modes.
