This problem is resolved for me. I'm not entirely sure how it came about but it is reminiscent of the old SCSI representation issues I used to see in Debian. After a set of updates the device (previously at /dev/hdb ) failed entirely when trying to burn DVD or CD material. But when I put in a video DVD I noticed that the device now comes up as /dev/scd0 . I re-targeted my scripts to /dev/scd0 and everything works fine.

It used to be the case that you had to have SCSI emulation on a CD burner for cdrecord to work with it. This required a boot option in the lilo.conf like:
append="hdb=ide-scsi max_scsi_luns=1"

As of the 2.6 kernel this was no longer entirely necessary to burn a CD, but often cdrecord would still give you trouble unless you did the scsi emulation.

What's odd to me here is that I have no scsi emulation in my boot options, the ide-scsi module is not loaded, whereas the scsi_mod is, and this device, which I'm certain is hooked up to an IDE cable is showing up as /dev/scd0 . I personally made no changes, just did the updates and rebooted when the update manager said I needed to.

I'm pleased that the issue is resolved, but I'm a little disturbed that Linux, which I thought I understood well, has now become slightly more occult. I have an ide device showing up as scd0 and really no idea how it got that way.

I haven't looked at it under Debian, but I believe the device is still /dev/hdb under that system.
