I recently purchased a 4TB Lacie USB3 Drive. Plugged it in and connected usb3 cable to usb3 port on my gigabyte UD7. Drive doesnt post in bios and is not recognised in windows.
I do manage to get it going if i unplug it from the mains and plug it in again. Installed usb 3 driver for it , not sure what else it could be???
