Please be gentle!

I am trying to create data disk archives on DVD. I have used XFburn, K3B, Brasero (junk) and Nautilus. In every case but one none of the utilities can locate a burning device.

The exception was the first use of XFBurn. It successfully burned one DVD. Every subsequent attempt fails due to the inability for a device to be found.

The device, an LG Electronics Internal Super Multi Drive Optical Drives GH24NSC0B, is new. Ubuntu found it after installation without problem.

Seems I remember something about editing a file entry somewhere but I can't get a query to hit that matches my condition precisely. Reminds me of trying to get WiFi drivers.

Snooze (neither a wire- nor propeller-head)


the device file of an optical burner is supposed to be /dev/srN, where N is a counting number beginning at 0. You need read-and-write permission for that file So what do you get from

ls -l /dev/sr*

The result might look like

brw-rw----+ 1 root disk 11, 0 2015-01-23 07:37 /dev/sr0

Although i am neither root nor in group disk, i can use it. The "+" says that there are ACL attached. In this case you may inquire them by

getfacl /dev/sr0

which in my case reports


If your desktop user lacks of rw-permission, then your superuser will have to grant them. For the duration while your system is running this may be done coarsely by

chmod a+rw /dev/sr0

But for a permanent solution, which survives reboot, you will have to check the udev configuration. (I love udev as much as you love Brasero.)

If this theory does not turn out to be true, try as superuser:

xorriso -devices

If this finds drives like

0  -dev '/dev/sr0' rwrw-- :  'TSSTcorp' 'CDDVDW SH-S203B'

then the superuser should be able to burn a DVD by e.g.

xorriso -outdev /dev/sr0 -blank as_needed \
        -for_backup -joliet on \
        -map /home/thomas/photos /photos \
        -map /home/thomas/movies /movies

xorriso command -map gets as first parameter the path of a directory or file on hard disk, and as second parameter the path which it shall get inside the ISO 9660 filesystem on DVD.

If the command xorriso --devices executed by the desktop user shows the drive too, then this user should be able to burn too.
