But you are right, I don't really need them. When troubleshooting, don't use symlinks.

This is what confuses > me... Makes perfect sense to me. Here's why: Whatever "cdrecord --scanbus" sees is what you get, *in that order*. So, the SCSI device with id=0 becomes sr0, which in your case is the CDROM. The SCSI device with id=1 is sr1, which is your burner. Try these on for size: to mount the burner: mount -t iso9660 /dev/sr1 /mnt/whatever to mount the CDROM: mount -t iso9660 /dev/sr0 /mnt/cdrom stick with raw block devices, and you'll save yourself alot of confusion. If these 2 above doin't work, i'd be quite surprised. Add symlinks once things work to your liking, not beforehand. ===== ~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~ Lonni J.
