    Question DVD Drive Not Showing

    Have finally migrated fully to Linux now after many years dual booting. But have one teething issue at the moment.

    Am running Ubuntu 10.10 Maverick (Linux Mint 10) x64bit

    Well I have two internal DVD Drives, one uses a SATA connection the other a basic IDE connection.

    The IDE drive currently works and shows up, but the SATA drive doesn't show up anywhere.

    The SATA drive is a TSST-Corp DVDRW Drive
    The IDE Drive is a HP DVDRW Drive (640 model or something)

    So the funny thing is, their is power to the TSST drive and it opens etc but just doesn't get recognized by the OS.

    But if I restart the computer and pop the Live CD into its drive it will boot into the Live CD and show up just fine.

    So am just looking for any ideas on how to get the SATA drive to work on my setup.

    Thanks in advance.

    Re: DVD Drive Not Showing

    Are you saying that when you put a disc in, it doesn't mount in /media and doesn't show up in nautilus? I seem to have that problem with (movie) DVDs that are encrypted sometimes, but data DVDs are ok.

    Or are you saying that the drive is not even listed in the Disk Utility program?

    thanks for the reply, the drive isn't even listed in the disk utility program.

    Re: DVD Drive Not Showing

    Ok I have done a bit of research and after looking in my /etc/fstab file there is no mention of any of my dvd drives.

    Code:
    # /etc/fstab: static file system information.
    #
    # Use 'blkid -o value -s UUID' to print the universally unique identifier
    # for a device; this may be used with UUID= as a more robust way to name
    # devices that works even if disks are added and removed. See fstab(5).
    #
    # <file system> <mount point>   <type>  <options>       <dump>  <pass>
    proc            /proc           proc    nodev,noexec,nosuid 0       0
    /dev/sdb5       /               ext4    errors=remount-ro 0       1
    # /home/THEVAULT was on /dev/sdb7 during installation
    UUID=0c6ea1fe-9ce0-4005-b3cf-037ba9d10410 /home/THEVAULT  ext4    defaults        0       2
    # swap was on /dev/sda5 during installation
    UUID=7786982c-3ea4-4488-8284-7e19eb7adfd1 none            swap    sw              0       0
    /dev/sdb6       none            swap    sw              0       0
    /dev/sda1	/media/TERA	ntfs	defaults	0	0
    This is pretty unusual IMO as am sure its supposed to even mount the one drive that I can use? even though at the moment I cannot burn disks with the HP Drive something about permissions keeps coming up in k3b.

    I also had a look at lshw -c disk to see whether my SATA TSST Corp DVD Drive would be shown and nope it isn't there, what would cause it not to show? It only shows my HP Drive?

    Code:
    terry@ORACLE ~ $ sudo lshw -c disk
    [sudo] password for terry:

    Re: DVD Drive Not Showing

    I don't think DVD drives are listed in fstab anymore since they tend to be automounted. My fstab doesn't list my DVD drive either.

    I'm not sure what your problem is, since it seems like the OS doesn't even recognize that there's hardware there. Maybe the SATA controller isn't exposing it for some reason, or there's a problem with the chipset driver.

    Have you tried disconnecting the HP drive and then seeing if the SATA drive can be detected?

    Re: DVD Drive Not Showing

    The above and what may be interesting is to boot to a liveCD using the ide drive and see if the sata drive is detected (adjust in bios if needed

    did you put this box together yourself or buy as is or close to?

    thanks for the advice, I have tried disconnecting the IDE drive and when I reboot back into Ubuntu there is nothing - no drives.

    Just for the record both drives work together in Windows 7, so it must be some misconfiguration with Ubuntu somewhere along the line.

    Is there no way (or a program) to auto-detect devices on the SATA bus?

    I think that's what the lshw command does. But if they're not listed (probably as sr1) in /dev/disk/by-path or /dev/block, then it seems the kernel isn't finding the hardware at all.

    You could try switching the SATA connection to a different one on the motherboard to see if it that works. And if not, I'd say it's something drive specific, and you might have to look for a driver or any known bugs with running that particular drive model in linux.
