[GTALUG] 10TB drive seen as a 2TB drive (twice?)

[Evan Leibovitch]

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.
