What happens when you execute this?
cdrecord -scanbus dev=ATAPI
This is what I get on my development system (Debian etch, kernel
2.6.18-3-k7). when I run the various scanbus commands:
# cdrecord -scanbus dev=ATA
scsibus1:
1,0,0 100) 'LITE-ON ' 'DVDRW SOHW-1673S' 'JS02' Removable CD-ROM
1,1,0 101) *
1,2,0 102) *
1,3,0 103) *
1,4,0 104) *
1,5,0 105) *
1,6,0 106) *
1,7,0 107) *
# cdrecord -scanbus dev=ATAPI
scsibus0:
0,0,0 0) 'LITE-ON ' 'DVDRW SOHW-1673S' 'JS02' Removable CD-ROM
0,1,0 1) *
0,2,0 2) *
0,3,0 3) *
0,4,0 4) *

Now, previously, I would have told you that this means you should use
one of these SCSI ids:
ATA:1,0,0
ATAPI:0,0,0
However, wodim doesn't support "ATAPI", and says it's deprecated.
# cdrecord -prcap dev=ATAPI:0,0,0
Warning, the ATAPI: method is considered deprecated on modern kernels!
Mapping device specification to dev=0,0,0 now.
To force the old ATAPI: method, replace ATAPI: with OLDATAPI:
cdrecord: Invalid argument.
Cannot open SCSI driver!
For possible targets try 'wodim -scanbus'.
For possible transport specifiers try 'wodim dev=help'.
For IDE/ATAPI devices configuration, see the file
README.ATAPI.setup from
the wodim documentation.
Instead, you have to use "OLDATAPI".
I've checked, and I can successfully write a disk with either
ATA:1,0,0 or OLDATAPI:0,0,0 on my development system. However, I/O
gets a little screwy with OLDATAPI -- the system is kind of
unresponsive -- and I'm not sure I can recommend using it.
Anyway, this suggests one change in Cedar Backup, which is to loosen
the regex around the SCSI parameter. That's probably a good general
change so I don't need to release a new version of my software every
time a new method needs to be supported. I've implemented it in
upstream Subversion as of revision 1014.
I'm going to dig a little further into your patch now and see what I
can do about supporting dev=/dev/cdrom and the like.
