HEXUS has discovered a new way to clear the Xbox 360 hard drive cache. Previously, you needed to reset your Xbox 360, and hold down the A button as a game was booting up. This new code allows you to clear the entire hard drive cache:
Go to the system blade and then select memory.
Press Y on the HD symbol and then press X,X,Left Bumper, Right Bumper, X,X. Once you do this a messsage will appear saying: Do you want to perform maintenance on your Xbox 360 storage devices?
Performing this function will also clear any software updates.
