This indicates it's a 512e drive, but your original post said it had 4096 byte logical sectors. > Is it then possible to make BIOS recognise this disk to allow booting?

Either gdisk or parted can be used to partition the drive correctly, using GPT partition scheme.

Do you know for sure that this computer can boot from a USB drive? If not I'd test that first, and use MBR partition scheme to eliminate that as a variable. It's also possible it's the combination of USB and GPT that causes the problem, that the BIOS becomes confused with a > 2.2TB drive being reported. You might ask these questions to Gigabyte tech support and see if USB booting of a GPT partitioned 3TB drive is possible.
