The drive (sandisk 4tb extreme pro - not without their issues I know) is plugged in via an apple thunderbolt cable directly to the port on the motherboard. I never use it for other devices, just drives.
Thinking further on it, there is another thunderbolt port next to it that works fine...
There will be settings on your BIOS, and in Windows, which control your Thunderbolt security and DMA settings. Most likely, a port profile has been set somewhere which forbids hot-plugging for that specific port/device.
