Wondering if that helps. Starting to wonder if it's the firmware on 
the USB external chassis.
Maybe as those numbers look better on the physical side. Try seeing if 
connecting it directly
to a open SATA port and see if that gets you 512 bytes for logical and 
4096 for physical. I've
suspecting that may be it based on the internal drive you proved sector 
size numbers.

Tried that. gdisk also reports 2TB and refuses to create any
partition larger than that.

While its stating that you have a sector size of 512 bytes which
is odd. Most gpt drives should
be 4096bytes per sector, I just double checked. So even if its gpt
it may be doing it based on
issues with other things, not sure if the computer or device your
using at a firmware level
supports 4K sectors but it seems maybe that should be checked. Its
a common problem
with larger drives, I've never run into it as the systems I have
are almost all UEFI or later.

The system already has an SSD as /dec/sda, and two disks one of 3TB

The disk model is WD101KFBX and its specs can be found here. 
All 
of the online guides I've consulted say that the full capacity of the

Is this a USB limitation? Or is there something else I need to change? 
I've attached the output of hwinfo if that's any help.


Thanks for any suggestions!



Your using fdisk right. There is a version for GPT disks called gdisk 
and you may want to try

that or a GUI program like gparted.
