Yeah I know, another one right? I have searched and have not found a answer to my specific question. I should be doing all the right things here. I own two self powered hard drives, both have Y cables. A Fat32 is connected to the back for all of my Wii games/emulator ROMs. The other hard drive is a Wii U formated drive for my Wii U games. It is plugged into the front of the unit. My Fat drive has UStealth on it, so there's no nag. All of my Wii apps I use have UStealth support so they all read the games off of my Fat USB drive. All goes well until I plug in my Wii U drive at the same time. It reads my Wii U games and works fully. I only have Wiiflow and USB Loader GX that reads Wii games off of my Fat drive at this point. Everything else can't read the Fat drive at all. I can unplug the Wii U drive, and everything goes back to working as they should. Is this just the trade off that the drive dissapeers once two different formats are running simultaneously?
