This is probably considered basic stuff but I'm still having trouble understanding dd.

In particular, why do the things it writes/reads to have to be *un*mounted?

How does the system even know that the device exists if it's not mounted?

What happens if you *do* write to a mounted device.

So far I've read about six dd how-tos, but I have not had the mounting explained to my feeble mind's satisfaction.

Anyone have a good url or simple explanation?
