ls -al /dev/cdrom*

This will tell you where these symbolic links point. You can grep your
dmesg for the result, as in "dmesg | grep sr0" to see which one it is
(if there is a symbolic link then something has detected it).

Untimately, dmesg tells you what was detected and you should be able to
mount it afterwards.

And they say you shouldn't edit /etc/fstab for removable media as it is
"not robust enough". This assumes gnome-volume-manager being able to
handle it better.
