OK. It would help if I knew how to debug the problem. But I found out on my own...
Debug output: ** (nautilus-cd-burner:6626): WARNING **: Couldn't unmount volume in drive: /dev/hda ** (nautilus-cd-burner:6626): WARNING **: Couldn't unmount volume in drive: /dev/hda # At this point the dialog pops up saying that the DVD has data on it.

Without it it tries to unmount using "unmount /dev/hda" which obviously fails with "umount: /dev/hda is not in the fstab (and you are not root)". You can see that n-c-b in feisty is built without gnome-mount support here: http://librarian.launchpad.net/7231251/buildlog_ubuntu-feisty-i386.nautilus-cd-burner_2.18.1-0ubuntu1_FULLYBUILT.txt.gz Search for "gnome-mount support: no" I cannot seem to compile n-c-b with gnome-mount support, even adding --enable-gnome-mount does not help. But that would probably fix my issue. Another option is to install pmount, which n-c-b uses if it's installed (I didn't have it installed, you probably have). This also fixes my problem. But then n-c-b really should depend on pmount if it's needed to function properly. So in summary, either: a) enable gnome-mount support in n-c-b, or b) let n-c-b depend on pmount -- Cannot burn on RW media because n-c-b does not unmount it https://bugs.launchpad.net/bugs/114770 You received this bug notification because you are a member of Ubuntu Desktop Bugs, which is a bug assignee. -- desktop-bugs mailing list desktop-bugs@lists.ubuntu.com https://lists.ubuntu.com/mailman/listinfo/desktop-bugs
