Pseudo-SCSI Adresses
cdrecord and cdrskin share only some syntax of addresses but not necessarily
cdrecord and cdrskin share the syntax of 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.
Standard mode uses scsibus,target,lun as given by the operating system. On
(old) real SCSI burners and on emulated SCSI it is compatible to cdrecord.
Standard mode tries to be compatible to original cdrecord. This should be true
with (emulated) SCSI where the /dev/sgN with is looked up with matching
scsibus,target,lun as given by the operating system.
With dev=ATA: or dev=ATAPI: the translation to /dev/hdX is purely literal
but matches the cdrecord addresses on all systems tested so far:
X = 'a' + 2 * scsibus + target
where target only may have the values 0 or 1.
On plain IDE this mode offers no compatible scsibus,target,lun addressing,
but the cdrecord-ly advised methods ATA:scsibus,target,lun and ATAPI:...
are supported by cdrskin via an own incompatible address enumeration.
In this mode, option -scanbus will list only SCSI devices unless option
dev=ATA or dev=ATAPI are given, which will suppress SCSI devices and only
show IDE drives (i.e. /dev/hdX without ide-scsi emulation).

Some programs or users have their own ideas about the address of their burner.
K3b 0.10 for example derives cdrecord addresses by own examination of the
devices and not by calling cdrecord -scanbus.
On systems where the burners are attached via (emulated) SCSI, standard mode
will hopefully be fully compatible. If IDE devices are used, then hope that
the frontend uses directly /dev/hdX or asks its "cdrecord:" via
dev=ATA -scanbus for drive addresses and drive descriptions.
Standard mode will hopefully be fully compatible with their ideas.
Old frontends which do not know dev=ATA or dev=ATAPI and which do ask their
"cdrecord" via -scanbus may be well served with option --old_pseudo_scsi_adr .
