"Me too". I have the identical problem on a Dell Inspiron 6400. Issue is discussed here: http://bugs.kde.org/show_bug.cgi?id=122568. Short version is that it appears to be that cdrecord wants to scan the SCSI bus again, but hasn't got read permission for /dev/sg0 (hard drive) so barfs before it can get to /dev/sg1 (DVD-RW).
Best workaround is here: https://launchpad.net/distros/ubuntu/+source/k3b/+bug/25380/comments/3. Other workarounds are to "dpkg-reconfigure cdrecord" and let it run as SUID, or to "chown root:cdrom /dev/sg0" after each reboot, in order of decreasing recommendedness The KDE bug indicates that a fix was committed to the K3b SVN on 30 October 2006. So that'll be in feisty, and not edgy, I assume -- says i do not have permission to use cdrecord https://launchpad.net/bugs/37423 -- kubuntu-bugs mailing list kubuntu-bugs@lists.ubuntu.com https://lists.ubuntu.com/mailman/listinfo/kubuntu-bugs
