With the greatest respects to the previous posters and there
suggestions... this has nothing to do with membership of plugdev, custom
udev rules to try and over-ride existing hal fdi, udev, and policykit
rules won't work.

Policykit knows two types of mountable drives - system and removable...
Policykit's definition of "removable" is:-
"Typically, system internal devices include non-removable internal hard
disks and other drives that are not easily added/removed by a local
console user. The heuristic typically used is that only devices on
removable media and devices connected via Firewire, USB, eSATA and SDIO
are considered external."

First remove all the customisations you've added to udev etc

Second look make sure you have no fstab entries for external drives.

Third, have a read of /etc/hal/fdi/policy/preferences.fdi

Fourth - right-click on the SOLID icon in the systray
choose "Device Notifier Settings"
in the pop-up dialog choose "Removable Devices" in the left-hand pane
Untick "Automatic mounting of removable media" and click on "OK"

If you're still stuck:-
Please paste the output of:-
ls -R /etc/hal
cat /etc/hal/fdi/policy/preferences.fdi
ls -R /etc/polkit-1
