I didn't realize this would be my first post.
Anyway, I recently finished building a computer. It has both a CD drive and a DVD drive. The first OS I installed was Slackware 13.1, and I used the DVD drive, since I used the DVD iso instead of the 6 CDs. That went over fine.
Then I installed Ubuntu 10.04 next to it, again, using the DVD drive to boot from (the CD drive worked, but it wouldn't boot from the CD drive, but booted from the DVD drive).
In Slackware's KDE, DVDs were recongnized, and so were CDs, and soon I thought nothing more of it. In Ubuntu, though, it wouldn't pick up DVDs, and now the DVD drive won't mount anymore.
It shows up when I go to Places from the menu, but it won't mount. It just says there is no media in the drive (even if there is), or that the drive doesn't exist (even though it does).
shows that it is there. It doesn't show up in /etc/fstab, but niether does the CD drive. The CD drive will show up in /etc/fstab when I put a CD in the drive. The DVD drive will just blink it's little light and twirl the DVD, then nothing.
I've tried making a mount point in /media/ called /media/dvd/ to use as a mount point, then ran the following command:
mount -o iso9660 ro /dev/sr0 /media/dvd/
and it will tell me that either the device does not exist (though it shows up by all of it's logical names in /dev/, in addition to everything above), or that there is no media in the device, even if it is something that used to work before the Ubuntu installation.
I've even tried some of the more bizarre things that I've seen in my hours and days of searches, including but not limited to, disabling the CD drive in the BIOS, starting with a blank DVD in the drive, adding the lines to /dev/fstab and then commenting them out, among other things.
Any and all help would be greatly appreciated. Thank you.
