I read about it on the internet, so it must be true...  ;-)  But
seriously, I should have said there's been "reports" of such a thing
"allegedly" happening, just to cover myself.  Of course we'll never know
if it's true, but I can see how it can happen by accident.  All it needs
is for someone dealing with a batch of drives, to accidentally skip a
step in handling incoming and outgoing, and one pending drive
erroneously becomes a done one.

Are *all* manufacturer's strict about how they manage it?  Do some
people return a drive through their dealer, rather than straight back to
the manufacturer, and might a dealer not bother to properly handle it?

George Orwell's '1984' was supposed to be a warning against tyranny, not
a set of instructions for supposedly democratic governments.
