I've been playing Darksiders now for some time now and I've noticed that when I start the game, in the main menu where it says "Press Start", it always triggers me to select a storage device. Why does it always ask? Is there a problem in my system, or is that just normal behavior? I never had this experience with any other game which I have played.
System:
XBox 360 slim 4GB with no additional storage devices.
