    CD drive not detected


    Hi All,

    I installed Knoppix 5.1 on my USB key (Persistent Home) and It works great. Only one small thing:

    I don't see my CD drive !!!

    What should I do to MOUNT or see my CD drive???

    I put a Music CD in there and no response from Knoppix. Looks like Knoppix thinks that there is NO CD drive. Sad

    Please Help,

    Marc.

    first of all check if it really doesn't recognize CD Driver.
    Open Konsole and execute this
    Code:
    su
    hdparm -I /dev/cdrom
    does it display correct info about your CD Drive.
    execute hdparm -I /dev/hda or sda too.
    It is amazing what you can accomplish if you do not care who gets the credit.

    it means, Knoppix is detecting your CD Drive.
    execute mount /dev/hdc or /dev/cdrom. does it mount CD and display its contents?

    It mounts OK.

    But when I open Kaffeine and click on Play Audio CD a message appears saying

    "NO Audio CD Found"

    Does Kaffeine play MP3's???

    If not, what software can I use to play MP3's???

    Another question:

    How do I list the content of the CD?? (I'm new to the LINUX world )

    Thanks for your HELP,

    Marc.

    you have to unmount CD first.
    Code:
    umount /dev/cdrom

    I have an error when trying to mount /dev/cdrom.

    root@Knoppix:/dev# mount /dev/cdrom
    mount: you must specify the filesystem type


    What Am I doing wrong?

    Thanks

    Here's the content of /etc/fstab:

    Code:
    knoppix@Knoppix:~$ cat /etc/fstab
    /proc      /proc       proc   rw,nosuid,nodev,noexec 0 0
    /sys       /sys        sysfs  rw,nosuid,nodev,noexec 0 0
    /dev/shm   /dev/shm    tmpfs  rw,nosuid,nodev,noexec 0 0
    /dev/pts   /dev/pts    devpts mode=0622           0 0
    /dev/fd0   /media/fd0  auto   user,noauto,exec,umask=000    0 0
    /dev/cdrom /media/cdrom  auto   user,noauto,exec,ro 0 0
    /dev/hda /media/hda  auto   users,noauto,exec,ro 0 0
    # Added by KNOPPIX
    /dev/sda1 /media/sda1 ntfs noauto,users,exec,umask=000,uid=knoppix,gid=knoppix 0 0
    # Added by KNOPPIX
    /dev/sdb1 /media/sdb1 vfat noauto,users,exec,umask=000,shortname=winnt,uid=knoppix,gid=knoppix 0 0
    # Added by KNOPPIX
    /dev/sdb2 /media/sdb2 vfat noauto,users,exec,umask=000,shortname=winnt,uid=knoppix,gid=knoppix 0 0
    Here's what I get for mount -l:

    Code:
    knoppix@Knoppix:~$ mount -l
    /dev/root on / type ext2 (rw)
    /dev/sda1 on /cdrom type fuseblk (ro,nosuid,nodev,noatime,allow_other,blksize=4096)

    persistent on /UNIONFS type aufs (rw,br:/KNOPPIX.IMG:/KNOPPIX)
