    Unable to mount cdrom0

    When I select the cdrom0 icon on my HP Pavilion ZX5000 running 9.10 I receive the following message:

    mount: special device /dev/scd0 does not exist

    I used the cdrom to install 9.10 and it worked on 7.10 and 8.04.

    You could go to Administration --> Users and Groups and click on your user name and then go to Properties and check that the cdrom check box has a tick in it under the user privileges tab. If not, unlock the user settings at the unlock button via your password and check the box next to cdrom. The problem is quite possibly a permissions issue. If the cdrom is owned by root, you may have to modify ownership of the device. If that doesn't help, please post the output of
    cat /etc/fstab

    The CD ROM Drives box is checked in the Users and Groups administration window. Below is the content of fstab as suggested.


    dale@dale-HP:~$ cat /etc/fstab
    # /etc/fstab: static file system information.
    # Use 'blkid -o value -s UUID' to print the universally unique identifier
    # for a device; this may be used with UUID= as a more robust way to name
    # devices that works even if disks are added and removed. See fstab(5).
    # <file system> <mount point> <type> <options> <dump> <pass>

    Hate to ask an obvious question, but is there a disk in the drive? My drives will only mount when I insert a disk into them.
    (exception .. floppy drive on Mythbuntu PVR mounts on boot! ... no clue as to why!! Bios??)

    sudo lshw -C disk
    in a terminal.

    if your cdrom is detected, the command should list the logical names:
           description: DVD-RAM writer
           product: DRW-1608P3S
           vendor: ASUS
           physical id: 0.0.0
           bus info: scsi@4:0.0.0
           logical name: /dev/cdrom
           logical name: /dev/cdrom0
           logical name: /dev/cdrw
           logical name: /dev/cdrw0
           logical name: /dev/dvd
           logical name: /dev/dvd0
           logical name: /dev/dvdrw
           logical name: /dev/dvdrw0
           logical name: /dev/scd0
           logical name: /dev/sr0
           version: 1.19
           capabilities: removable audio cd-r cd-rw dvd dvd-r dvd-ram
           configuration: ansiversion=5 status=open
    replace /dev/scd0 in fsatb with one of the names listed by lshw.

    Thanks for the suggestions. I think it needed a disk in the drive. Seems to work now.

    Hey. I'm having the same issue...I dont' want to hijack the original post, but I'm eager to see what the solution will be.
