Seagate Backup Hub - PC freezes at BIOS splash when connected

[Genuine]

Hello.

OS: Windows 7 Ultimate
Motherboard: Gigabyte Z77X-D3H with BIOS version F18g

My backup USB drive only works properly when it is connected while Windows is logged in. When I try to boot up my PC with the drive connected and powered on my PC will freeze at the BIOS splash screen. It will not boot with the drive plugged in. When I attempt to connect the drive while in the BIOS menu the menu will immediately freeze.

This is what I have tried so far with no success:
1. Different USB ports
2. Disabling Legacy storage boot & switching to different UEFI boot option combinations in BIOS

Genuine, you may need to run Disk Part Clean as there could be a problem with its image. (this WILL erase your data) The drive is fine and you may test it with Seatools for Windows to confirm.
