Did you partition that drive?  This is a bit of a grey area.  i.e. should I be just using 
drives with a 4K block size (The Microsoft Windows approach) or should I be using a GPT 
partition table?

I've only every gone the GPT route but I've also never tried using a >2TB drive  to boot 
from.  Obviously I've never tried to boot from a GPT partitioned drive.

Also the 4K block size approach only gets you to 16TB.  We'll be using drives that size in 
a fortnight or two.
