Try this sequence ( the device in this case is /dev/sda1 )

                               $ pumount /dev/sda1

Comment: OK, no errors so it is unmounted now...

peter at prospero:~ $ pmount /dev/sda1

Comment: No errors, so now it's mounted again.

So, with the "stick" still plugged in, the system still "knows" it is
there after the "pumount" command , but ...

peter at prospero:~ $ eject /dev/sda1
peter at prospero:~ $ pmount /dev/sda1
Error: device /dev/sda1 does not exist

... after "eject", the system has total amnesia about it ;-)

That's a /highly technical explanation/ of the difference, I know   *grin*
