DVD-RW does not mount in Ubuntu 12.04 LTS

Question

I try to use CDs and DVDs in my Ubuntu Precise Pangolin (12.04 LTS), but the system doesn't mount the DVD-Recorder when the DVD or CD is ready to use. What is the solution for this problem? How Ubuntu 12.04 LTS can mount optical media (CD, DVD, Blu-Ray) recorders?

Solution

non-blank media:
As it seems, by default non-blank media (CD, DVD) does not mount automatically. But it should show up in nautilus. Click on the entry in your left side of a nautilus browser under devices and the media should mount.

blank media:
Blank media is mounting automatically on my Ubuntu 12.04. I think it is the default behaviour.

nothing shows up:
If there is nothing new in the devices area in nautilus, this is a bad sign. Your drive might not be connected (check the cables).

As ashutosh pointed out, to find out if the recorder was recognized, type dmesg | grep "sr0" in a terminal. You should get a response similar to:

[    1.649270] sr0: scsi3-mmc drive: 40x/40x writer dvd-ram cd/rw xa/form2 cdda tray
[    1.649445] sr 0:0:0:0: Attached scsi CD-ROM sr0

check mounted non-blank media:
To be sure there it is not mounted execute this in a terminal: mount | grep "/dev/sr"
If the response is blank there is no non-blank media mounted in your media drive. Blank media is not showing up here.

Note:
your drive might be called sr1 or sr2 if you have several; in that case replace sr0 with sr1 in that case (or simply sr to catch them all).

what is the output of dmesg | grep sr0 ? and also when you mount the ususal way, what error are you getting?

I also have same problem - it seems to work ONCE - that is ubuntu 12.04 will correctly auto mount a blank DVD ONCE per session then any subsequent blank DVD put into tray will NOT auto mount until next reboot - this has been true for several ubuntu releases
