    Hmm that wasnt the part of dmesg I was hoping for. See if there's a file /var/log/boot.msg or something similar, or use dmesg right after boot. When it boots, during the probing ide things stage, you will see a message similar to this if it is detected:
    It might go by too fast to see it, which is why you should check dmesg or your /var/log/boot.msg (or similar if you have it) to see if it is detected. Another way to find this out is through /proc/ide. cd to /proc/ide and you will see links to hda, hdb, etc. Go into each one and you'll see a file model, cat each one and hope one of em says your dvd drive.

    Yeah, I went to /var/log/dmesg and this is what I found:

    The emphasis (bold) is mine. Linux detects the drive but it won't show up.

    Yes, Linux found your drive at boot and assigned it "hdd" name.
    Now it is up to you to mount this drive somewhere.
    For example:

    # mkdir /mnt/hdd (create the mount point)
    # mount /dev/hdd /mnt/hdd

    You must do this as root and then set read/write permissions for users.
    Now your software can access this drive through its mount point.
    (Some multimedia programs, however, like these devices unmounted)
