Hrm.
For the 4TB disk in the same system (which has been working for years), fdisk -l reports:

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.

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.
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.
