PC's today can't even use 3TB HD's to boot with. From what I understand to go to 3 TB you would need a 128 bit computer.
Utter rubbish
My boot disk is a 3TB, single partition and it's working fine under Windows7 x64 and I've had RAID arrays before now much bigger than 3TB as boot drives.
BUT my motherboard has UEFI and not BIOS
