I realise this is a very specific issue indeed, and also kind of a '1st world' issue... but I'd like to know what's causing my Gigabyte P57Xv7 laptop to boot twice, every time whenever my 4TB Seagate Backup Plus USB3.0 drive is connected to it. Here are the salient points:
The Seagate is drive W: in the info below. The other two drives are both logical drives of an SSD. Everything is NTFS.
Thanks for any suggestions for any further troubleshooting I may be able to perform!

- The first boot doesn't even make it to the spinning Windows circle, it only gets to the initial Gigabyte screen, then after a few seconds it reboots.
- It's not the same type of double boot that occurs whenever you first plug in a new USB device (which I assume is for the BIOS to enumerate the new device?) - those boots are much shorter than this one.
- It only boots twice when the boot is from a shutdown state. Not when it's a Windows 10 restart.
- However I doubt it's a Windows issue, as it happens even when I disable Windows Boot Manager in BIOS (which makes the laptop boot straight into BIOS instead of loading Windows 10)
- I've tried various BIOS settings (like enabling/disabling USB Legacy Support)
- I've also tried various Windows settings (like disabling Hibernation and playing with various Power settings)
- The Seagate drive is not a boot drive, and there are no hidden/system files in the root directory. Its file system in NTFS.
- The drive has passed all of Seagate's tests via its SeaTools program.
- While I don't have an awful lot of other hardware to play with, I can tell you that 1) the Seagate does not cause another older laptop to do the same thing; and 2) another different model Seagate USB3.0 drive does not cause the Gigabyte to boot twice.
