Hmmm. It's been a while since I've used FreeBSD but I gather it copes
with unmounting the device (save for a few complaints in the kernel
log). Were I at home at the moment, I'd check to see if DragonFly did
the same, but vague memories (it's not the sort of thing I often do)
suggest it copes similarly.

Of course, any operating system is going to have some trouble if the
underlying storage is whipped out and cache isn't written. It's
customary to unmount under BSD and Linux, whilst it's customary to
'stop' the device in Windows, so everything really deals with it in the
same way.
