Ok, that makes sense (or sort of). Thanks for explaining this.

I can't follow you here. I can plug and unplug the USB hard disk in
question, so it's what could be called "removable". In HAL's terminology
it's hotpluggable, but *not* removable. This is the main problem I'm
having: I want to be able to simply plug it in and mount it. But since
pmount is requires both removable and hotpluggable (as you said it should)
it obviously fails.

Now I'm wondering why my USB stick is marked as removable. Is this a bug?
Of course, if it were a bug, then pmount would be nearly completely useless
since most USB storage media (except CD/DVD drives) aren't "removable".
