yes, I first thought that your DVD-R was mounted iso9660 under feisty and gutsy.
Concerning the first problem under feisty, indeed there is a bug with the mount command, here is what happens: - it tries mount with udf, it fails because it can't mount it read-write - it tries mount with iso9660, it fails because it can't mount it read-write then it tries to mount it readonly, but it didn't reinitialize the fs types list and retry with iso9660 instead of udf, so: - it tries to mount directly with iso9660 and succeeds. This bug has been fixed in gutsy, I don't know how to have bug fixed in feisty, maybe you can request a backport. However there is an easy workaround, just add the ro option for the cdrom in /etc/fstab: /dev/scd0 /media/cdrom0 udf,iso9660 user,noauto,ro 0 0 Then mount will directly succeed to mount the dvd with udf even under feisty (with the mount command). Concerning your second problem, that's a different bug, but can you do this ? hal-device | egrep " udi|scd0" | grep -B 1 scd0 and retrieve the udi of the cdrom device (take the first one) then do: gnome-mount --hal-udi <the_udi_found> does it mount the DVD ? If it doesn't work, do: sudo strace -f gnome-mount --hal-udi <the_udi_found> 2> gnome-mount.strace.txt and attach the trace file. -- Mounting UDF should be preferred over ISO9660 https://bugs.launchpad.net/bugs/112584 You received this bug notification because you are a member of Ubuntu Bugs, which is the bug contact for Ubuntu. -- ubuntu-bugs mailing list ubuntu-bugs@lists.ubuntu.com https://lists.ubuntu.com/mailman/listinfo/ubuntu-bugs
