[Bug 200337] Re: CD/DVD burning problem in hardy SOLVED --- BURN AT 2X

[Dave]

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.
