Tried the disable fast boot trick and that didn't help. I sent my laptop back to HP and they checked it out and said there was no problem with the computer. An MS tech went thru the system before I sent the computer to HP and he said there was no problem with the windows 10. The Seagate Slim 1 tb hdd drive works fine on the USB 3 port of my ASUS q302la, but only after I switched off legacy USB support in the BIOS, a solution for which the ASUS tech seemed to be familiar with. So does anyone know how to actually resolve the problem with a HP Starwars laptop and Seagate drive on the USB 3 port.
