Problems have been reported with devices larger than a terabyte.  Also,
in general, most drivers are only safe up to a terabyte -- some can go
to 2, but it's driver dependent in 2.4.x and so it was deemed better to
err on the side of caution since I don't have hardware to investigate
with.

It wasn't working, that's why it's set to 1 TB.
