    Question DVD / CD randomly unmount/disappear on ASUS X83Vm-X1

    Fairly straightforward, as the subject reads, Ubuntu 8.10 issue that I don't replicate when sorrowfully running Vista so I can watch a movie or listen to a CD on this laptop.
    DVDs or CDs randomly unmount/disappear on ASUS X83Vm-X1.
    This happens consistently with the DVD or CD, or it does not happen at all.


    What happens:
    1. Insert DVD or CD
    2. Select program to access it with
    3. Program hangs or dies (VLC, Totem, Mplayer, Audio Extractor, AcidRip, etc)
    4. Force-quit program and manually kill runaway CPU-sucking processes (at least for Audio Extractor)
    5. .....
    6. Fail

    To retrieve the CD or DVD, I have to:
    1. Shut down
    2. Once BIOS comes up, I have to shut down AGAIN
    3. Restart
    4. During boot up, eject the CD/DVD

    I have tried manually re-mounting or re-discovering the CD or DVD and it does not work, many variants on sudo mount, never finds it.
    It looks like I don't A) Have an FSTAB or MTAB entry for the CD/DVD drive.

    FSTAB:
    Code:
    # <file system> <mount point>   <type>  <options>       <dump>  <pass>
    proc            /proc           proc        defaults    0   0
    # /dev/sda7
    UUID=424ae514-ea70-4162-a73e-2ee32a621f7f     /               ext3        defaults,errors=remount-ro    0   0
    # /dev/sda6
    UUID=8EA863F7A863DBE9       /media/drv0       ntfs-3g         defaults      0   0
    # /dev/sda8
    UUID=25987d86-2484-43a1-838a-7c953172e569      none            swap        sw          0   0
    Sudo of lshw, only entry I found that might apply:
    Code:
               *-cdrom
                    description: DVD-RAM writer
                    physical id: 1
                    bus info: scsi@1:0.0.0
                    logical name: /dev/scd0
                    logical name: /dev/sr0
                    capabilities: audio cd-r cd-rw dvd dvd-r dvd-ram
                    configuration: status=open
    If anyone has any thoughts, I would appreciate it. The CD ROM thinks it's open, for some reason, unless I misread the lshw, and thinks that until the reboot clears the status.

    With a DVD in the drive, one of the ones that doesn't "fail":
    Code:
    *-cdrom
                    description: DVD-RAM writer
                    product: DVDRAM GSA-T50L

                    physical id: 1
                    bus info: scsi@1:0.0.0
                    logical name: /dev/cdrom
                    logical name: /dev/cdrw
                    logical name: /dev/dvd
                    logical name: /dev/dvdrw
                    logical name: /dev/scd0
                    logical name: /dev/sr0
                    logical name: /media/1000036992
                    version: SR04
                    capabilities: removable audio cd-r cd-rw dvd dvd-r dvd-ram
                    configuration: ansiversion=5 mount.fstype=udf mount.options=ro,nosuid,nodev,uid=1000,utf8 state=mounted status=ready
                  *-medium
                       physical id: 0
                       logical name: /dev/cdrom
                       logical name: /media/1000036992
                       configuration: mount.fstype=udf mount.options=ro,nosuid,nodev,uid=1000,utf8 state=mounted

    Any thoughts on this would be welcome, even if you can definitively say, "You are Out of Luck, I tried it myself" because its frustrating never knowing if your media will work, or be temporarily 'eaten'.

    Re: DVD / CD randomly unmount/disappear on ASUS X83Vm-X1

    I see no new word on this. I have an ASUS A8V-VM SE with similar issues runing Jaunty 9.04. When I boot with a CD or DVD in my Drives they mount correctly I can see them listed in the "Places" drop down menu. I can Open the drive and look at the contents even change disks and all remounts correctly.

    ted@Grayhound:~$ sudo lshw -C disk

    *-cdrom:0
    description: DVD reader
    product: DVD-ROM DDU1615
    vendor: SONY
    physical id: 0
    bus info: scsi@2:0.0.0
    logical name: /dev/cdrom
    logical name: /dev/dvd
    logical name: /dev/scd0
    logical name: /dev/sr0
    logical name: /media/Roxio11
    version: FYS3
    capabilities: removable audio dvd
    configuration: ansiversion=5 mount.fstype=udf mount.options=ro,nosuid,nodev,uid=1000,utf8 state=mounted status=ready
    *-medium
    physical id: 0
    logical name: /dev/cdrom
    logical name: /media/Roxio11
    configuration: mount.fstype=udf mount.options=ro,nosuid,nodev,uid=1000,utf8 state=mounted

    After some period of time, and not long, the drives disappear or becomes unresponsive. They are visible to the file system but unmoutable. Any attempt to access the drive yields a "Unable to mount location, no media in the drive " Error.

    Now lshw -C disk reads for the same drive as:

    *-cdrom:0
    description: DVD reader
    physical id: 0
    bus info: scsi@2:0.0.0
    logical name: /dev/cdrom
    logical name: /dev/dvd
    logical name: /dev/scd0
    logical name: /dev/sr0
    capabilities: audio dvd
    configuration: status=open

    I've noted that the system no longer knows the product nor vendor information for the drive as well as the status=open when the doors are not. Is this a mother board issue, gnome, linux, or ...?

    Any guidance would be greatly appreciated.

    Re: DVD / CD randomly unmount/disappear on ASUS X83Vm-X1

    Solved at last, with a firmware update!
    Had to
    Code:
    sodu lswh | grep DVD
    Then find the firmware for it (mine is a GSA-T50L), then boot Windows, download the firmware.
    In my case, downloaded 5 versions from diff sides, tried to MD5sum compare, none matched, and just took the risk - the HP firmware update failed to install, too! So I had to go with an un-verified one from a forum. Bleh.
    But the DVD drive no longer fails every time I try to use the darn thing. Makes a huge difference in my ability to stick to Linux on this laptop - except the part where the firmware required booting to Windows to install.
    WHOOT.

    The SOLVED comment above never worked for me. Upgraded to 11.04 awhile ago. Been watching my DVD/CD ROM drives closely. Be it the newest Kernel or 11.04 whichever but my drives are now remembering who they are and I am happy again.
