Hrm. For the 4TB disk in the same system (which has been working for years), fdisk -l reports: Disk /dev/sdc: 3.7 TiB, 4000787030016 bytes, 7814037168 sectors Units: sectors of 1 * 512 = 512 bytes Sector size (logical/physical): 512 bytes / 4096 bytes I/O size (minimum/optimal): 4096 bytes / 4096 bytes Disklabel type: gpt Disk identifier: 88C7DF91-CD80-4EEB-AC6B-110119B04DD4 Device Start End Sectors Size Type /dev/sdc1 2048 7814035455 7814033408 3.7T Linux filesystem Wondering if that helps. Starting to wonder if it's the firmware on the USB external chassis. On Sun, 29 Dec 2019 at 00:42, Nicholas Krause <xerofoify@gmail.com> wrote:

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.
