I have an Etch box with a linux-image-2.6.18-5-k7. All works well but

wodim -devices
Beginning native device scan. This may take a while ...
wodim: Invalid argument. Cannot Set SG_SET_TIMEOUT

Apt-get install wodim confirms I have the latest release. I have also
run apt-get dist-upgrade but still get the same result from wodim -devices.

What's wrong?

What is the output of wodim -scanbus ?

What device does your CD-ROM/DVD normally use?

Is your optical drive accessed through the normal ATAPI driver or
through ide-scsi (SCSI emulation for IDE devices)?

Is SCSI compiled into your kernel--at least as a module? If so, is that
module loaded? I think that the 'sg' (SCSI general?) module is used by
wodim.

--------------------
I'm running Sarge with kernel 2.6.22 and wodim (self compiled) 1.1.6.
Even though 2.6 kernels support writing to ATAPI optical drives, I'm
still using ide-scsi to drive my CD writer.

Can't open SCSI driver!

Note that I am using the linux-image kernel, not a kernel compiled from
a linux-source kernel package. Apparently the linux-image kernel is not
compiled with scsi emulation.

/dev/hdc I can mount it as /media/cdrom0 and read data files from a cd

The output of less /proc/ide/hdc/driver is ide-cdrom version 4.61

The output of lsmod includes ide_cd and cdrom which uses ide_cd.

insmod sg finds no such module.

In lsmod I find ide_cd and cdrom uses ide_cd

I am using a linux-image-2.6.18 kernel. Apparently it was not compiled
with SCSI emulation as this should not be needed.

SCSI emulation is probably compiled as a module. Put this on the kernel
command line:

hdc=ide-scsi

That should allow the SCSI emulation driver to take control of that
interface. You might have to "modprobe ide-scsi" after bootup.
