Not so. I see my external disk as available under VBox Windows (guest)
even while it's already mounted under F14 (host). I don't use it of
course, that would be crazy, but it's certainly there. Same happens if I
plugin a pendrive or iPhone. They show up under both systems.

To the OP: my memory is hazy on this, but I think you need to a)
shutdown the guest (not just pause it), b) go to the "add disk" dialogue
under VBox, possibly under the Machine menu, c) add the disk as a new
attachment to IDE or SATA and note its device name, d) fire up the guest
system and try to mount the device. Something along those lines in any
case.

And as a last resort, you could always read the manual :-)
