Try it on F17.
use "shutdown -h now" as the way to cleanly turn off especially to avoid mounting/unmounting manually - USB drives are ok with shutdown -h now
My point exactly is that there may be distro differences at least between F15 and F18 . . .
it was my experience with F15 that always got me to switch user to root before logging off -
F17 and F18 we have seemed to verify it is a matter of having another user somewhere on the field -
typically me but in a root terminal on a multiple desktop.
