I can't seem to be able to mount my optical drive. I have tried numerous solutions from this site with no results. I am not able to see the device inside the file browser either. There is a DVD in the drive. I am running 12.04 on an HP g60-235dx portable. I have a link below to the specs. I will also list what I have tried (that I can find back right now.) I know the drive is functioning, because just before Windows 7 crashed and my MBR went fubar I was watching movies just fine. I am fairly new to linux, so don't assume I know anything. Ok, so here is what I have tried:

sudo wget --output-document=/etc/apt/sources.list.d/medibuntu.list http://www.medibuntu.org/sources.list.d/$(lsb_release -cs).list
sudo apt-get --quiet update
sudo apt-get --yes --quiet --allow-unauthenticated install medibuntu-keyring
sudo apt-get --quiet update
sudo apt-get install libdvdcss2

dmesg | grep sr0 (no output)

apt-get install libdvdnav4 (already installed, and up to date)

sudo /usr/share/doc/libdvdread4/install-css.sh

You list the output of a bunch of diagnostics. Maybe I'm missing it, but I don't see where you describe what you do that actually fails, or what the symptom of failure is (error message?). Have you tried reading a data DVD (not a video DVD) on linux on this machine? Have you tried reading a data CD? When you describe the problem as "won't mount," that doesn't quite make sense to me. "Mount" normally means that you make a filesystem accessible; that's not what you're trying to do here, because it's not a data DVD with a filesystem on it. –  Ben Crowell Sep 10 '12 at 23:56
    
I'm trying to watch a DVD, burn discs, and just use the drive in general. Nothing I can find is getting it to do that. nothing happens when I enter a data cd or dvd either, I have a bunch of photos burned to a disc that I cant access. the drive never shows up to the left side when browsing files. –  CyborgGold Sep 11 '12 at 6:45
    
@Mik I'm running Nautilus 3.4.2, I dont see anywhere to change that setting –  CyborgGold Sep 12 '12 at 2:25
    
The drive is now showing up in Disk Utility, but it still says 'No Media' when there is a disc in the drive, and I still cannot do anything at all with the drive. –  CyborgGold Sep 12 '12 at 2:31
    
@CyborgGold don't worry about my other comment- I forgot you were running Nautilus. You could try running sudo apt-get install --reinstall udisks and log out and in again and then put your disk in and see if it mounted automatically. Are you able to mount the disk manually? Try udisks --mount /dev/sr0 if this is your device name. Also try wodim --prcap dev=/dev/sr0 (with no disk in the drive). –  user76204 Sep 12 '12 at 14:08

Try the following terminal commands with a disk in the drive:

sudo mount -t iso9660 /dev/sr0 /cdrom

or more simply

sudo mount /dev/sr0 /cdrom

If you get an error message to the effect of "no media in drive" the most likely reason is a faulty drive. Unfortunately dvd/cd drives are a lot more fragile than most people realise - a piece of fluff or a scratch on the lens can render them useless. Even worse, laptop drives that have the lens on the carriage that is ejected from the device leave them very susceptible to physical damage.

You could have a hardware problem. Try mounting it manually

mount /dev/cdrom /mnt/cdrom 
cd /mnt
ls

I put this post in another answer but it is actually quite simple:

A lot of people have had this problem, as I first did with the dvd and cd mounting. You have to make a directory for the folder within media. Be sure to run as root.

sudo -s

cd mkdir /media/[folder_name]

If you have any error regarding read/write issues you will have to chmod

Warning, If You do not know what you are doing I would suggest NOT doing this!

sudo -s

cd /media

chmod ugo+rwx

I hope this helped! The main problem is that the drive will not unmount itself after inserting a disk. Creating a directory solves this problem.

returns:
