It's a compromise to avoid hours of low-level formatting before you can
use a drive. New drives will come from the factory formatted in a
special way that can be switched instantaneously. But once you start
writing you're stuck with it.
That's ridiculously stupid. All you need is an offset parameter, which
can be flipped at will. Now, flipping it will obviously scramble all
data, but there is absolutely no reason why it shouldn't be possible to
instantaneously flip it back and forth.
