My setup was working perfectly for quite a while, until I eventually sold my 1tb WD My Book Essentials usb 2.0 HDD.. I've recently purchased a new HDD, 1tb WD My Book Essentials dual usb 2.0/3.0. Now, some games will black screen me when loading a new zone or screen or whatever. The only difference with this HDD is that the cable is 2-in-1 2.0/3.0 usb. I was thinking it was a sleep mode issue, but I used the WD Smartware Software and changed the sleep timer from "15m" to "never", yet it will still black screen me after a bit of gameplay.. specifically, Skyward Sword. I haven't played too many games with this new HDD yet, but it seems after a while of inactivity.. (nothing new being loaded in the game) it's basically clockwork.. as I will play SMG2 for 1+hr without issue, Mario Kart, Rayman.. . No black screens. So I'm not sure what kind of issue this is. I'm still thinking it might be a sleep mode problem, and I can assume this will effect more games in the future. At the moment Skyward Sword is unplayable. Any ideas appreciated, thanks!
