    Default Can't mount cdrom

    Hi,
    After I installed RH8 from CDROM I couldn't mount the CDROM after the
    installation.It seemsed to be a problem which occurs a lot of times
    but I didn't found any solution.

    My system RH8 with kernel 2.4.20-13.8. Following I describe my system
    and error message.
    fstab : /dev/cdrom /mnt/cdrom iso9660 noauto,user,kudzu,ro 0 0

    Wenn I tried to mount I becom next error message : wrong fs type, bad
    option, bad superblock on /dev/cdrom, or too many mounted file system

    dmesg shows:
    ide1: BM-DMA at 0x2048-0x204f, BIOS settings: hdc:DMA, hdd:pio
    hdc: attached ide-cdrom driver.
    hdc: ATAPI 14X CD-ROM drive, 128kB Cache, DMA
    Uniform CD-ROM driver Revision: 3.12
    cdrom: This disc doesn't have any tracks I recognize!

    hdc: cdrom_read_from_buffer: buffer botch (129)
    end_request: I/O error, dev 16:00 (hdc), sector 129
    isofs_read_super: bread failed, dev=16:00, iso_blknum=32, block=64
    FAT: bogus logical sector size 36857
    VFS: Can't find a valid FAT filesystem on dev 16:00.

    In the dev directory the following link occurs:
    lrwxrwxrwx 1 root root 8 Sep 12 21:34 /dev/cdrom ->
    /d
    ev/hdc

    With hdparm /dev/cdrom I get the following output:
    dev/cdrom:
    HDIO_GET_MULTCOUNT failed: Invalid argument
    IO_support = 0 (default 16-bit)
    unmaskirq = 0 (off)
    using_dma = 0 (off)
    keepsettings = 0 (off)
    readonly = 1 (on)
    readahead = 8 (on)
    HDIO_GETGEO failed: Invalid argument


    What must or can I do to make my CDROM working?

    Thanx in advantage

    This is close, but it only allows for the mounting of iso9660 CD's not UDF
    formatted or audio (music) CD's
    > What must or can I do to make my CDROM working?
    Well first, you do not have to mount audio (music) CD's you just use one
    of the many applications and play them.

    Second, modify the entry in /etc/fstab to read something like;

    /dev/hdc /mnt/cdrom udf,iso9660 noauto,user,ro 0 0

    And lastly upgrade to the currently available kernel from Red Hat.

    I don't use audio cd's on mine system.

    I did change the entry but still got the same error message when I
    tried to mount the CDROM.

    I will update the system but I saw nothing what should describe mine
    problem. I still think it's a configuration problem.

    Have you checked your CDROM media? Some of the recordable media appear
    to
    look the same on both sides. One side is for the lebel, but also looks
    like the
    recording side.
