just microsoft being microsoft

A while back I was having problems with my Xbox 360 finding all disks unreadable. The first thing the tech support person had me try was clearing the memory cache. This is a simple procedure that, as far as the tech support person knows, doesn't do any harm to the 360 or change any settings; it just clears up some problems.

So how do you clear the memory cache? Do you go to settings and memory and choose the "clear cache" option? You do not, because there is no "clear cache" option. Instead, you go to settings, memory, and then press X X left bumper right bumper X X.

Seriously, Microsoft has a hidden key combination to fix memory issues with your 360. What the fuck?
