I've gone through the same scenario. I believe the USB 
layer/interface/driver/whatever in C5 is the pinch point. I have SATA 
attached GPT labeled 3TB disks working just fine in C5. Put the very 
same disk in a USB enclosure and it's not recognized as 3TB - sees it as 
some fraction of its true size.

I know the same disk/enclosure worked on Win7 & I'm pretty sure it 
worked on C6.
