Make sure that your user has permission to any required device files and executable programs. In [Debian], the files have the appropriate permissions for people in the __cdrom__ group. If you add yourself to the group you will have to log out and back in for that to take effect.
!!! How to get your CDR working - [ATAPI] Styles
-Recent 2.4 kernels, and all 2.6 kernels, have support for cdwriting via [ATAPI]. There is however a whole heap of crap going on at the moment over this
, with Linus slagging off
the cdrecord author for sticking to an outdated
and hideous interface
, and the cdrecord author slagging off linux in general because of its shite compatability with the standards he wants
.
+Recent 2.4 kernels, and all 2.6 kernels, have support for cdwriting via [ATAPI].
+Historically
, the cdrecord program only worked over [SCSI]
and the Linux users needed SCSI-emulation
, and there was argument over whether this was
the kernel's fault or
cdrecord's fault
.
(See http://lkml.org/lkml/2003/11/6/151 for Linus's take on this, and see [README.ATAPI|http://www.wlug.org.nz/archive/docs/cdrecord-README.ATAPI] for the author's take.) [This slashdot post|http://linux.slashdot.org/comments.pl?sid=141120&cid=11825433] better explains both points of view.

-!! Why would you want to do this?

-The main reason might be that you dont have to piss round with ide-scsi emulation and so on. However, the bigger reason is that it appears that ide-scsi has a major bug in it which wont be fixed any time in a hurry, and so if you want cdwriting to _work_ under 2.6 you'll want to use the [ATAPI] interface. Another reason is that its such a pain in the ass to change between using ide-scsi and ide-cd if you want to go from, say, writing a cd to playing a dvd, and you have one of those nifty combo cdr/dvd drives.
!! What to do:
Make sure you have the [ATAPI] Cdrom driver compiled in or as a module in your system. Probably best if you disable ide-scsi emulation while you're at it. (That is, make sure no drives are told to use the scsi emulation on boot. Either remove ide-scsi support from your kernel, or check your boot loader's (either [LILO] or [GRUB]) configuration to make sure it doesn't pass any <tt>hd''x''=ide-scsi</tt> options to the kernel.)

Now find your CDR with __cdrecord dev=ATA: -scanbus__. Note the dev=ATA: bit. (Warning: Case matters - "ATA" works, "ata" does not.)

Basically you can still burn the CD but would recommend you don't do other things at the same time that hog CPU or else you may burn a coaster.
