Can't read any CD or DVD in Ubuntu Gnome?

I can't mount any CD or DVD on Ubuntu Gnome.

I tried to run:

sudo mount -a

but it wasn't successfully.

Here is output after sudo lshw -C disk:

 *-disk description: ATA Disk product: ST9500420AS vendor: Seagate physical id: 0.0.0 bus info: scsi@0:0.0.0 logical name: /dev/sda version: 0006 serial: 5VJ40L7T size: 465GiB (500GB) capabilities: partitioned partitioned:dos configuration: ansiversion=5 sectorsize=512 signature=000c0194 *-cdrom description: DVD-RAM writer product: CDDVDW TS-L633N vendor: hp physical id: 0.0.0 bus info: scsi@1:0.0.0 logical name: /dev/cdrom logical name: /dev/sr0 version: 0300 capabilities: removable audio cd-r cd-rw dvd dvd-r dvd-ram configuration: ansiversion=5 status=nodisc

after mount next output:

Here is output after cat /etc/fstab:

How to solve this trouble?

Instead of mount -a, use the proper command:

sudo mount /dev/sr0 /media/$USER/<mountpoint>

... replacing <mountpoint> with the name of a real directory in /media/<username> where <username> is the all-lowercase name of the user account.
