Well, I see some possibilities for creative solution here, using some
ssd (or usb stick or mdconfig as act of desperation) and gconcat, but
it's asking for trouble and should probably be considered a temporary
hack.
What I personally would do is get a 2TB drive and use it instead, with
gpt and -l for label, and replace it as gpt/something. Using 100 or so
MB less than whole disk is also a good idea, as you can see ;)
Cheers and good luck.
