I'm facing issues when using by very first time my CD/DVD drive in Linux.

Back when I had Linux, it worked normal, CD/DVD rw, but since I didn't use it much, I just removed it from the laptop (you know, I have a HP Pavilion dv4, those ones you can remove safely the CD/DVD unit from, and place a protector instead, to decrease weight). I just connected it again when I needed to use it, and it was ok.

Couple of months ago I started using Linux, first Ubuntu 12.04, and then I'm in ElementaryOS Luna (Ubuntu based), and no problems at all, except for today, that I needed to use my unit and it didn't work. (Need to say here, I installed both versions, Unity and eOS w/out the unit in place, so I guess that messed up some configuration files from the very start)

I have done some research, and some useful info is here, (note: during all the terminal commands, THERE WAS a CD in the unit)

I guess this one is to look up for drives?

~$ wodim --devices
wodim: Overview of accessible drives (1 found) :
 0  dev='/dev/sg1'  rwrw-- : 'hp' 'BD ROM BC-5501S'
~$ mount '/dev/sg1'
mount: can't find /dev/sg1 in /etc/fstab or /etc/mtab

here the /dev dir cdrom, cdrw, dcd and dvdrw, and some others, are in pink, is that normal?

and trying again to mount manually...

~$ sudo mount /media/cdrom0/ -o unhide
mount: can't find /media/cdrom0/ in /etc/fstab or /etc/mtab
~$ sudo mount /dev/cdrom /media/cdrom
mount: mount point /media/cdrom does not exist
~$ sudo mount /dev/cd /media/cdrom

~$ sudo mount /dev/dvd /media/cdrom
mount: mount point /media/cdrom does not exist
~$ sudo mount /dev/dvdrw /media/cdrom
mount: mount point /media/cdrom does not exist
~$ sudo mount /dev/sr0 /media/cdrom
mount: mount point /media/cdrom does not exist

Any help to get my unit mount correctly CD/DVD? Thanks in advance.

The question is a bit old by now, but still doesn't have an answer. So:

  • It appears the folder /media/cdrom doesn't exists, that's why you get "mount point ... does not exist".

  • Second, as /dev/cdrom is not included on fstab, if you want to mount it manually you must specify the type of filesystem with the -t parameter. Fortunately, there's an auto option.

So you'll need:

mkdir /media/cdrom
sudo mount -t auto /dev/cdrom /media/cdrom

Hope that helps!

Thanks a lot but unfortunately I have no way to test it, since I changed machine and os :( not because of this haha –  unmultimedio Feb 19 at 3:12
