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.
