  1. DVD Drive won't read DVD discs. Weird dmesg log.

    Hello. Problem is simple - can't read DVD discs (actually i can mount
    them, i can list files, but i`t wont work further). It`s new (2nd one
    already, thought, that 1st had a deffect or what). It's a Samsung SATA
    rom.

    This is not a codec problem.
    Info about the machine:

    Linux
    (just updated, using Ubuntu 8.04, fresh one)

    When my cdrom mounts, it outputs following stuff on dmesg:

    Other stuff about cdrom (it shows 2nd (IDE) cdrom also, which i tested
    and it didnt read anything, thou it reads that disc on the other -
    windows machine. Don't know why it shows up there, because i de-

  2. Re: DVD Drive won't read DVD discs. Weird dmesg log.

    Forgot to asq questions: How would you translate dmesg log? Is there a
    problem with my pc, or the OS?
    One of the lines says i should update drivers or something. But, as i
    was googling for it, it just said the line is a bug.

    It might be a problem with the SATA port or with the SATA controller. If
    you have more than one type of SATA controller on your motherboard try
    connecting to a different controller. Core2 motherboards frequently have
    two controllers, most SATA connectors are on an Intel chip and then there
    are a couple that are on something else (JMicron is common).

    Just tried a brand new IDE drive. (This one:
    http://www.samsungoms-europe.com/sam...02&group=multi
    )
    Same thing happens - can`t play DVD. But can play CD.

    This looks like a software bug. Or maybe motherboard has been damaged
    somehow?

    Well i tried some noname stuff, they didn't work on Ubuntu. But it did
    work on Windows machine, from which i took it...
    Btw i see that a newer kernel is available, but it won't install with
    sudo apt-get upgrade command. So i`ll try to compile it.

    Owell, it's too complicated for mee to compile kernel. Did like
    howtoforge says but, well... it's just too complicated for me - won't
    boot up with my new kernel.
    Would be good if i could just apt-get upgrade...
    But i can't.

    Building a kernel is easy, here is the step by step,

    Untar the kernel

    Copy the .config file from the source directory of the distro's kernel,
    this will configure your kernel with all of the options that your distro
    has chosen. On Redhat systems the .config file is in

    /usr/src/kernels/2.6.25.6-55.fc9.x86_64/.config

    I don't know where they put in on a Debian family, but it must be there
    somewhere.

    After that do

    make gconfig

    This will bring up a GUI that will allow you to customize the kernel

    Then build and install it as follows (you must be root to do this),

    make -j 2 all
    make modules_install
    make install

    BTW, I really doubt that this is a kernel problem. DVDs use a standard
    interface and it's been supported forever.

    Did you try my suggestion of using a different SATA connector?

    Thanks for the tutorial. I managed to compile , but not boot with the
    new kernel, but i`ll leave that there. It is as you say - dvd drives
    have been supported forever.

    I tried using a different sata connector, yes. I even tried using
    different PATA drives, none of them worked on that machine.

    Btw i`m using the 64 bit version. Maybe there is a problem...

    No, i tried number of DVD`s. And those DVD`s are working in other
    drives.

    I've been running 64 bit Linux for years on lots of machines, I've never
    had a problem with a DVD reader except when I had a DVD reader die. CD and
    DVD players are fully supported and there are no problems with them. The
    fact that you couldn't get a PATA drive to work leads me to the conclusion
    that you have another problem, either a hardware problem like bad memory
    or a bad bridge chip, or a software problem like a corrupted OS. I wrote a
    system exerciser that checks for hardware reliability, I suggest that you
    download it and run it,

    http://www.polybus.com/sys_basher_web/

    If sys_basher doesn't find anything the next thing I would do is to do a
    fresh install of the OS on a separate partition if you have one, if you
    don't then I'd reinstall over your current partition. Make sure that you
    do a clean install so that you know that you have a fresh copy of
    everything.

    If its a data DVD, you have a problem -- it's either a bad disc, or
    player. But, from the output, it doesn't look that way.

    It looks like you are running into "DVD copy protection" (not CSS).
    Ignore the problem - mplayer, xine, mythtv (with libdecss installed)
    will play your movie just fine. You just can't access it as a "data
    DVD", which is what you seem to be doing.

    The DVD is actually slightly malformed, and is causing the data read to
    read parts of the disc which just aren't there.

    Load up Mythtv, it has a good DVD player and ripper. Should take you to
    that good place, where DVDs can be ripped, and it never rains.

    Or something.

    On the previous HDD, which was really damaged (couldn`t read sectors,
    that are on the outside of the platter), i couldn't play dvd`s also
    (identical, err, same problems). No other parts have been damaged. I
    didn't have so much time to fix that, so i ended up on installing
    Windows on that computer (which plays those DVDs well).
    It`s just too much effort.

    Sorry that I can't test it with your program anymore.

    Those DVDs are rented (and playing well on other OSes, players

    By the way, if it was a corrupted image then, anyway, i did a kernel
    upgrade. (not the .25 version, but some minor upgrade from
    24.something to 24.something+1).

    I guess it`s some other hardware incompatibility (with Linux)....
    don't know.

    Anyway, thank you all so much for the help.
