    Smile DVD drive not working

    Hi gang. Noob with questoins here. I have been doing extensive searching on these forums to solve my issue. I can do certain things with my DVD drive currently, but not mount. I have found postings that have solved this issue for some and not others.

    So far I am in the "others" category.

    Before I start posting my Fstabs and such (I am still getting used to commands) I want to list a little of what is going on.

    1.) I can use the Eject command and eject the drive through the terminal
    2.) I can get a no Mount point error
    3.) I have run a command or two to audit my system, and my drive does show up in the command.

    I guess my initial queston is this:

    Does it matter if the drive is set to cable select, slave or master? I am only using one drive, and one hard drive.

    Does the Master/Slave/CS matter at all? I believe I am set to Cable select.

    I KNOW this drive is not broken. It is new and I installed Ubuntu with it. When in Ubuntu, however, can't read an instered disk. Yes I have tried a few different disks.

    Thanks! I am sure this is my first of many posts.

    Re: DVD drive not working

    It would certainly be worth posting your /etc/fstab file with
    Code:
    cat /etc/fstab
    , and also the output of
    Code:
    ls /media
    to see if there is an entry for the cd/dvd drive, and also to see if there is a folder for it to mount to in /media.

    Re: DVD drive not working

    I can do that, although I was hoping you could clarify:

    What does the fstab file do?

    What is the "cat" command?


    Here are my results - thank you!

    Re: DVD drive not working

    Tried adjusting the Drive to CS, Slave, or Master. None work.

    If I navigate to Places > Computer and try to access the DVD drive icon, I receive the "Unable to mount Location - there is no media in the drive" error.

    There is media in the drive. Have tried different disks.

    The disks I tried were widows based and the install cd for ubuntu. I can boot up from the disk, but can't access the drive if I try to access through the OS.

    A little frustrating, but this will be killer when I get it working.

    I do not know what KArmic is, but I am using the latest version of Ubuntu, 9.04

    Re: DVD drive not working

    Not sure what is going on but the output from those two commands is more or less exactly as it should be, so I'm baffled.

    For your information, the cat command just displays the contents of a file. If it's plain text it shows that, if it's a binary it just shows gobbledegook, but it will do no harm. To see what a command does use
    Code:
    man command
    in a terminal and the manual will appear.

    Look here for more quick info.

    Re: DVD drive not working

    Thank you for the command list. That will be useful. This seems to be a fairly large hurdle to ovecome.. at least I get to practice some commands.

    Re: DVD drive not working

    Would it make sense for me to reinstall the OS? I haven't done too much with the system yet so I wouldn't be rolling back that far.

    It did take me a few tries to install the system to start.... perhaps there was some corruption or incorrect initialization?

    Make sense?

    Re: DVD drive not working

    It's not just you. I am having the identical problem. I installed ubuntu 9.04 on my desktop from a DVD. I know that the drive is physically all right because it ran from the BIOS, the system booted from the DVD drive and the drive worked perfectly until after installation was complete.

    The DVD drive initially showed on my desktop until I tried to access it. Then I got the "spinning wheel" or whatever it is for a while and then that stopped and the icon for the drive was gone - all without ever accessing the drive.

    Thereafter, I could find the drive in my "places" but when I tried to access it I received an error message that it couldn't mount the drive.

    This is all rather frustrating because ubuntu works perfectly on my Asus 901 netbook and functions properly with all USB peripherals including stand beside DVD drives and hard drives.
