    /dev/cdrom not a valid block device---Iam stuck. Pls help.

    Hi geeks out there hope you can help me.

    I am using RH9.0 with a MONOLITHIC KERNEL-2.4.22. I am running in a text
    mode.

    I have a really big, big problem--cant mount my cdrom.

    I been in many mailing list but cant find answer that my address my
    concerns.

    The problem only arises when I compiled to the latest kernel. I remember
    that I even included cdrom support for my system.

    My problem is this everytime i mount my CDROM
    #mount /mnt/cdrom
    /dev/cdrom not a valid block device


    My /etc/fstab looks like this:

    /dev/cdrom /mnt/cdrom udf,iso9660 noauto,owner,ro,unhide 0 0

    #cat /proc/devices
    2 fd
    3 ide0
    7 loop
    9 md
    22 ide1

    #cat /proc/filesystems
    iso9660

    #ls -l /dev/cdrom
    /dev/cdrom -> /dev/scd0

    #ls /dev/cdrom
    /dev/cdrom

    I also tried providing the entries in my grub.conf
    hdd=scsi-ide

    But nothing seem to bring good news.

    And Iam sure my cdrom is working. Therefore, hardware issue is should
    not be an issue.

    I also checked this but nothing seems to be working. Maybe because it is applicable to a MODULARIZED KERNEL.

    I even replace my CDRW with a CDROM. But no good news = (

    Hope you can help me. Please

    I'm pretty sure it should look be "ide-scsi" instead of "scsi-ide".

    Also, are you trying to mount an audio cd? If that's true, then I don't think you can. I seem to remember reading something that audio cd's don't have filesystems, so you can't really mount them. But can you put an audio cd in your drive and play it? I know that when I put an audio cd in my drive and try to mount it, I get a similar "error" but can still listen to it via xmms or whatever you're using.

    Does /dev/cdrom exist? If not, try making a symlink to /dev/scsci/scd0 or /dev/scd0, whichever exists. And it should indeed be hdd=ide-scsi

    Hello,
    Having a monolithic kernel should not matter at all - just make sure you inlcuded all the reuqired options.
