UEFI can address 4TB. If you are using BIOS, that could be a problem. With 512-byte sectors, 2TB is about the maximum representable offset.
BTW all the documentation I've seen about BIOS boot sequences assume 512-byte logical sectors. How is BIOS supposed to handle 1024-byte or larger logical sectors?
We've gone, I think, to GPT on our new builds. Root drives are running 2TB these days for us, and we're not setting on UEFI. Note that a lot of the drives are actually 4k sectors, but present them, logically, as 512byte sectors.
That is why I specified logical sectors.
