    Can't mount Cdrom drive



    Here is the contents of my /etc/fstab

    LABEL=/ / ext3 defaults 1 1
    LABEL=/boot /boot ext3 defaults 1 2
    none /dev/pts devpts gid=5,mode=620 0 0
    none /proc proc defaults 0 0
    none /dev/shm tmpfs defaults 0 0
    /dev/hda3 swap swap defaults 0 0
    /dev/cdrom /mnt/cdrom udf,iso9660 noauto,owner,kudzu,ro 0 0
    /dev/cdrom1 /mnt/cdrom1 udf,iso9660 noauto,owner,kudzu,ro 0 0

    i USED THESE COMMANDS:
    mount /dev/cdrom /mnt/cdrom
    mount /dev/cdrom1 /mnt/cdrom1

    THE ERROR IS BELOW:
    /dev/cdrom1: Input/output error
    mount: block device /dev/cdrom1 is write-protected, mounting read-only
    /dev/cdrom1: Input/output error
    mount: you must specify the filesystem type

    I read on a site that the command to check if the cdrom has been identified correctly by the kernel was: dmesg | more
    when I ran the command I got this:

    cdrom: open failed.
    cdrom: open failed.
    cdrom: open failed.
    I/O error: dev 0b:01, sector 0
    I/O error: dev 0b:01, sector 64
    I/O error: dev 0b:01, sector 0
    I/O error: dev 0b:01, sector 64
    I/O error: dev 0b:01, sector 0
    FAT: unable to read boot sector
    I/O error: dev 0b:01, sector 64
    isofs_read_super: bread failed, dev=0b:01, iso_blknum=16, block=16
    I/O error: dev 0b:01, sector 0
    I/O error: dev 0b:01, sector 64
    I/O error: dev 0b:01, sector 0
    I/O error: dev 0b:01, sector 64
    I/O error: dev 0b:01, sector 0
    FAT: unable to read boot sector

    Im assuming there is some sort of hardware problem with my cdrom drives. I ran the dmesg | more before and the kernel did identify the cdrom.

    One thing I failed to mention is that when I'm in GNOME the cd plays. I put the cd in the cdrom and it autoruns. It detects the contents of my cd and plays.

    I dont get it

    Are you doing this as root?

    You don't mount an audio cd at the command line.
    You media player accesses the files without that step.
    It may be that your sole purpose in life is simply to serve as a warning to others.

    Try using either:

    Code:
    /dev/cdrom /mnt/cdrom iso9660 noauto,owner,kudzu,ro 0 0
/dev/cdrom1 /mnt/cdrom1 iso9660 noauto,owner,kudzu,ro 0 0
    or:

    Code:
    /dev/cdrom /mnt/cdrom udf noauto,owner,kudzu,ro 0 0
/dev/cdrom1 /mnt/cdrom1 udf noauto,owner,kudzu,ro 0 0
    (not 'udf,iso9660')

    What is 'kudzu'?

    Also, it would probably help you to know that:

    ~ Once defined in /etc/fstab, a device can be mounted simply by referring only to either the device directory or the mount directory (ex. 'mount /dev/cdrom' or 'mount /mnt/cdrom') -- mount reads /etc/fstab and gets the rest...

    kudzu is an app that comes with rh that detects various devices, if i remember corectly. like mentioned above you can't mount audio cds even if you are root.

    If you can't mount an audio cds, can you mount a cd that has data files on it?

    Just answered my own question. I just placed a windows install cd in the cd player just to see if i could get to it using /mnt/cdrom

    I was able to get to it. So data cds you can mount from the CLI, audio cds you cant mount from the CLI. Is that right?

    thats exactly the same as it is on mine. GNOME works fine for mounting. KDE doesn't. to mount a cdrom, i have to reboot the pc before it works again in KDE. if i eject the cd and put another one in, half the time it mounts and the other half it simply doesn't recognise that there is a cd in the drive....so i have to reboot again . i've tried everything without success.
