Thanks for all of the advice. This time around I ran the command provided by mark to wipe the drive. Then I used the Bigdisk 6 and the 2.01 w/hijack. Emplode shows 298GB free and I'm now testing a sync. Everything looks good so far.

I did use Marks big disk builder previously and for some reason I was having some sort of an issue with the full drive space not showing up. This is why I ran the regular builder and then the big disk builder. I think wiping the drive completely might have helped this time around.
