1. Turn on your Xbox 360.
2. Scroll across to the system tab and select the storage devices option.
3. Highlight the hard drive or memory unit option (it should say "Hard Drive, 12 GB free", for example).
4. (on NXE) Press Y for "Drive options".
5. Enter the following button sequence: X, X, LB, RB, X, X. The following message should appear: "Do you want to perform maintenance on your Xbox 360 storage devices?"
6. Select "Yes".
7. Restart your console. You have now cleared your hard drive cache and your Xbox 360 should run faster and have improved game-play on certain games (The Elder Scrolls: Oblivion, Fallout 3, Halo 3, or other games).

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
