Hi,

I have two optical drives in my system, a Samsung DVD burner attached to
the PATA adapter and a Plextor CD burner attached to a SCSI adapter
card. Both drives give me problems under the Ubuntu 10.04 LTS release
(installed first on my PC) and under the Xubuntu 10.04 LTS release
(installed now). Both drives on the other hand function perfectly under
SUSE 11.0, which I fortunately still have on another partition on my
hard disk.

The problem is the following: When I insert a disk into the DVD burner, it is not automatically recognized and mounted by the system. It doesn't show up under the Places menu, and also not in the file system category of the thunar file browser.
The only way I can get to see and mount it, is with the disk utility (see attached screenshot).

The CD burner also behaves strange. After adding the lines:

/dev/sr0 /media/dvdrw iso9660,udf user,auto,exec,utf8 0 0
/dev/sr1 /media/cdrw iso9660,udf user,auto,exec,utf8 0 0

to /etc/fstab, it at least now automatically mounts written CDs and displays them on the desktop, but when I insert a blank
CD, it is displayed in the disk utility as a 2.2 TB volume, which brasero doesn't want to write to ... (also see screenshot)

When I check /var/log/kern.log, I see lots of error messages:

I'm not expert enough to diagnose from these messages where the problem
lies, so any suggestions would be welcome !
