When in gnome-files, double clicking an unmounted partition does nothing. No prompt for a user password (sudo) password (desired action). No error message. etc.
When in Xfce4, the un-mounted partitions appear on the desktop (this is normal), when they are double clicked to mount, the root password is requested (should be the user password for sudo).
