Thread: Read UDF CD's

  1. #1

    Default Read UDF CD's

    I backed up lots of my pictures, music, and documents onto disks using Windows Vista's native CD/DVD burner. When I put the discs into my laptops CD/DVD drive it says:

    UDF Volume - KDE Daemon
    A new medium has been detected
    Medium type: Unmounted CD Writer

    When I choose to open in a new window, I get an error in Konqueror saying:

    mount: block device /dev/hdb is write-protected, mounting read-only mount: wrong fs type, bad option, bad superblock on /dev/hdb, missing codepage or other error In some cases useful info is found in syslog - try dmesg | tail or so

    I've searched for the problem and it seems Linux can't read discs using the UDF filesystem. I've installed UDFtools in Yast but the problem still remains. I have a Phillips DVD-RAM SDVD8821 with OpenSUSE 10.2 running KDE.

    Is there anyway I can get Konqueror to read the discs?

    Thanks for any help or advice.

    When searching through the forum I found a few other unreplied queries about UDF discs. Are they completely unreadable in Linux? Any help or advice would be great.

    Thanks.

    try the following:

    open console, log in as su and enter root password:

    mkdir /mnt/dvd
    mount -t udf /dev/sr0 /mnt/dvd
    chmod 777 /mnt/dvd

    should work, works for me. can make an fstab entry if you wish.

    this assumes your dvd drive is /dev/sr0, it might be different

    It says that "mount: special device /dev/sr0 does not exist". I presume my DVD drive must be somewhere else, how do I find where it is?

    Thanks very much for your help.

    According to your initial posting in this thread it's at /dev/hdb :-p

    Thanks, but when I try that I get the following:

    mount: block device /dev/hdb is write-protected, mounting read-only
    mount: wrong fs type, bad option, bad superblock on /dev/hdb,
    missing codepage or other error
    In some cases useful info is found in syslog - try
    dmesg | tail or so
    Which is the same error message I got before.

    Did you follow that advice?
    What does your syslog say?

    I'm sorry, but where is the system log stored in Linux? I've looked in /var/log but I don't know which one to look in?

    /var/log/messages would be the best bet. Alternatively, the dmesg
    command will work on openSUSE too, but you'll want to capture its
    output in a file for perusal, like so:
    # dmesg > /tmp/dmesg.out

    Thanks for the help, this is in messages:

    Jun 25 09:39:00 tim-laptop kernel: UDF-fs: No fileset found
    and this in dmesg, it says the same thing:
    UDF-fs: No fileset found
    My system is completely up-to-date as I've run through the online update, so I don't know what I else need to do. Any suggestions?
