as Rahul Sundaram said some time back...
https://www.redhat.com/archives/fedora-list/2008-March/msg02024.html
controlling how and when drives are mounted is obfuscated somewhere in the 
layers of
"Udev. HAL, DBus and gnome-volume-manager/KDE equivalent.

http://www.linuxjournal.com/article/7745
"


also useful reading:
"Howto prevent F9 from mounting all mountable partitions"
https://www.redhat.com/archives/fedora-list/2008-September/msg00862.html
"How to hide a disk?"
https://www.redhat.com/archives/fedora-list/2007-December/msg01207.html

And Uh No I don't have it figured out yet either.
