And program is recomended from Western digital.Problem is if i go and play games and exit game and then connection to this hdd is just lost. Same thing happen sometimes, when try more than one job from/on him in same time.Other whey it work but only when start windows again (it need for some reason to shut Pc and turn of power again) restart wont work. Just like said, it need to get power again from beginning. Thanks.
