Take a look at 

 http://freedesktop.org/Software/hal 

specifically the 0.4 spec (most distros ship hal 0.4.x) for which there
is a snapshot here

 http://people.redhat.com/davidz/hal-spec/hal-spec.html

Things will likely change (but not too much) until we hit 1.0, but then
we'll freeze all the API's.

You may also want to look at gnome-volume-manager here

 http://cvs.gnome.org/viewcvs/gnome-volume-manager/

as g-v-m does somewhat what you want to do.

Good luck,
David
