    Unhappy Can no longer browse or 'ls' CD or DVD disks.


    I can still play Movie DVD's, or listen to audio CD's on my DVD drive, and CD drive. I can not <cd> to those drives and list the files, or use "my computer" or "konquer" to browse data files on them.

    Does anyone have any reason this happened or how to fix it?

    I'm using Suse 10.1 64 bit and KDE

    You probably just need to mount the disk.

    I don't think it is a mount problem.

    1)
    The "My computer" icon in KDE not only shows the drive, but also the name of whatever CD or DVD is in the drive.

    2)
    As the first post says, linux, can play audio CD's and movie DVDs'.

    3) I can see the CD or DVD drive under /mount
    /media>ls -al
    total 1
    drwxr-xr-x 4 root root 112 2006-08-24 11:10 .
    drwxr-xr-x 25 root root 592 2006-08-28 09:56 ..
    drwxr-xr-x 2 root root 48 2006-08-16 15:59 cdrecorder
    drwxr-xr-x 2 root root 48 2006-08-16 15:59 dvdrecorder


    when I cd to the drive,
    >cd cdrecorder/
    >ls -al
    total 0
    drwxr-xr-x 2 root root 48 2006-08-16 15:59 .
    drwxr-xr-x 4 root root 112 2006-08-24 11:10 ..

    That's all that shows up

    If I click the drive in KDE's mycomputer icon I get permission denied.

    Actually, this looks very much like a mount problem - if you don't have some form of "auto-mount" (i.e., udev) running on your system.

    Your 'ls' output from your previous post looks like a mount point that has nothing mounted on it (normally an empty directory).

    Whatever programs you are running [that work] may be (probably are) handling the mount/unmount operations for you automatically.

    Try mounting '/media/cdrecorder' or '/media/dvdrecorder' manually:

    Code:
    mount /media/cdrecorder
    mount /media/dvdrecorder
    or try re-mounting everything:

    Code:
    mount -a
    Otherwise, please post the '*recorder' lines of your '/etc/fstab' file.

    (Or the whole file, if you wish...)

    Don't worry -- you'll probably get the next one...

    EDIT:
    And I am usually a little slower than most in getting a post written...

    I was asuming that since the name of the disk was shown, the disk was mounted. I must be wrong. Thanks for the reply,

    Here's the output of mount;

    Code:
    # mount /media/cdrecorder
    mount: unknown filesystem type 'subfs'
    No joy.

    Here's the CD / DVD section of fstab;

    Code:
    # cat /etc/fstab
    
    /dev/hdc             /media/dvdrecorder   subfs      noauto,fs=cdfss,ro,procuid,nosuid,nodev,exec,iocharset=utf8 0 0
    /dev/hdd             /media/cdrecorder    subfs      noauto,fs=cdfss,ro,procuid,nosuid,nodev,exec,iocharset=utf8 0 0

    Based on the fact that in your original post, you said "I can still..." - I am guessing that perhaps you may have udev, but it is not running...

    As a check - what does this yield?:

    Code:
    ls -ld /etc/udev /etc/init.d/boot.udev /usr/bin/udevinfo /sbin/udev*

    What does that mean?

    What do these commands yield? (as root):

    Code:
    grep subfs /proc/modules /proc/mounts /var/log/boot.msg 
    grep subfs /var/log/messages | tail
    grep subfs /var/log/warn | tail
    udevinfo -d | grep -A 6 block
    ls -al /sys/block/hd*
