In this tutorial, we learn how to clear your Xbox 360's hard drive cache. First, go to the system settings on your "my xbox" tab. Next, go to memory, then hit "y" for device options. Now, enter these buttons "x,x,lb,rb,x,x" with your remote to clear the cache. Now, hit yes when the new window pops up on your screen. After this, your cache will be cleared and you can now install any updates your games have to offer. This is a great way to clear out your cache in just a couple of minutes, and avoid a slow running and outdated game.
