Hi! I just installed 12.04LTS. My machine has multiple problems.

1. Neither of my DVD R/W drives appear on the desktop, in the launcher, or in the file manager when I put media in them. Where are they supposed to appear? I know the drives are physically recognized, because if I put a video in either drive, and run the VLC media player, I can open the disk by selecting /dev/dvd1 or /dev/dvd2.

2. Where are my thumb drives? They don't appear anywhere either.

Any assistance with this is appreciated.
