I have a brand new xbox 360 3.4 gb game console. I bought an external hard drive 250gb. When I try to install a game. On the menu it says play game or install game. These are the only 2 options on the menu. I select install and it goes to a screen sayin No valid storage devices found. But if I go to the systems menu and then to memory it shows my external hard drive. And it will let me move from internal hard drive to the external hard drive no problem and visa versa.
It just will not let me install a game, WHY
Please if you can help me....... frustrated ME
