Package: cdrdao Version: 1:1.2.1-6 The subject describes what I believe the nature of the problem to be, but here are some details that I think will prove it.
I'm a member of the "cdrom" group so I should have access to my CD devices: [EMAIL PROTECTED] ~$ ls -l /dev/scd* /dev/sg* brw-rw---- 1 root cdrom 11, 0 Jun 5 14:05 /dev/scd0 brw-rw---- 1 root cdrom 11, 1 Jun 5 14:05 /dev/scd1 crw-rw---- 1 root root 21, 0 Jun 5 14:05 /dev/sg0 crw-rw---- 1 root cdrom 21, 1 Jun 5 14:05 /dev/sg1 crw-rw---- 1 root cdrom 21, 2 Jun 5 14:05 /dev/sg2 However, sg0 is a hard disk, so I do not have access to this (as a normal user). The cdrdao package does not (AFAIK) have an option to install cdrdao suid root. Attempting to scan for devices fails: [EMAIL PROTECTED] ~$ cdrdao scanbus Cdrdao version 1.2.1 - (C) Andreas Mueller <[EMAIL PROTECTED]> SCSI interface library - (C) Joerg Schilling Paranoia DAE library - (C) Monty Check http://cdrdao.sourceforge.net/drives.html#dt for current driver tables. And that is all I get. If I become root, I do get a device listing: [EMAIL PROTECTED] ~# cdrdao scanbus Cdrdao version 1.2.1 - (C) Andreas Mueller <[EMAIL PROTECTED]> SCSI interface library - (C) Joerg Schilling Paranoia DAE library - (C) Monty Check http://cdrdao.sourceforge.net/drives.html#dt for current driver tables. Using libscg version 'schily-0.8' 0,2,0 : PIONEER , DVD-ROM DVD-303R, 2.00 0,6,0 : YAMAHA , CRW3200S , 1.0d AFAICT, what is happening is that cdrdao is trying to access sg0, failing with EACCES, and aborting the scan.

FWIW, cdrecord suffers from the same problem, and I've filed a separate bug for that. I could be wrong, but I think that this bug in cdrdao may be the reason why k3b cannot detect my CD devices (which then makes k3b unusable). Let me know if I can help.
