Can anyone help me understand what happened when I tried to burn a CD,
and what I can do (if anything) to fix up the CD?
The burn seemed to go alright until the end, when it hung up and
eventually failed (see log below). I can now read the CD when I put
it in the writer, but not when I put it in the CD reader. mount
/cdrom gives, after a pause, the error "mount: No medium found". I
can mount and read regular CDs there, and the drive is only a couple
of years old, so I think it should be able to handle CD-Rs.
Here's the output of cdrecord trying to get multi-session info:

I have an ATAPI drive (Sony CDU 928E) and built a
custom kernel (2.2.18pre21) with scsi-ide and related modules. I am
using the scsi-ide for the writer (formerly /dev/hdd) but have left
the reader (/dev/hdc) alone. This means I have 2 drivers governing
the same ide channel (if that's the right term). I don't know if that
could cause trouble. There was nothing in hdc during the whole recording.

When I first set things up I had both CD drives showing as SCSI, but
now only the writer does. I believe this is a result of ide-cd
grabbing the regular CD drive before ide-scsi gets it. Since I had
set things up with the 2 SCSIs, this led to some of the [oops] below.
I used GnomeToaster 0.3 under a potato system with bits of woody. I
specified multi-session for this backup (data CD). Here are some of
its preference lines:
Recorder device /dev/scd1 [oops]
mount point /cdrom [oops]
SCSI id 0,0,0 [I edited this before I recorded]
recording client cdrecord
Fixating Command rec_clientrec_multisessionrec_dummymode
dev=rec_scsiid speed=rec_speed -fix
Trackwrite command rec_clientrec_multisessionrec_dummymode dev=rec_scsiid
speed=rec_speed -nofix -$tracktype -
Finally, here is the log of the toaster session. I tried a test
without a write first; I'm not sure if that's still reflected in the
log. (The test also hung at the end, but I hoped it would go away...)

Since I'm using modules, this probably doesn't matter.

Finally, when I started gtoaster I got the error
wheat:/usr/local/rootlog# gtoaster
GnomeUI-WARNING **: While connecting to session manager:
Authentication Rejected, reason : None of the authentication protocols
specified are supported and host-based authentication failed.
I assumed this was a result of launching gtoaster as root when I had
started the X session as my regular user account.
