How to Defrag an Xbox 360 Hard Driveby Matthew Anderson ; Updated September 22, 2017
The Xbox 360 hard drive stores a large number of permanent and temporary files during use. The physical distance on the hard drive between files used by the same game can be large enough to cause a slight delay in the game. This issue is referred to as fragmentation. It is possible to defrag an Xbox 360 hard drive by clearing the console system cache. This process will remove the temporary files causing the fragmentation issues. This allows the console to save game files physically closer on the drive since old temporary files are no longer in the way.
Turn on the Xbox 360 console to open the Dashboard menu.
Highlight “My Xbox” in the Dashboard menu.
Select “System Settings” from the “My Xbox” section of the menu. Press right on the controller to scroll through the “My Xbox” section options. Press the “X” button on the controller to select it from the menu.
Select “Memory” from the system settings. It is the third option from the top of the list.
Highlight the Xbox 360 hard drive in the storage devices selection menu.
Press the “Y” button on the controller to open the hard drive options menu. “Clear System Cache” may not initially be visible on the menu. This is the option needed to defrag an Xbox 360 hard drive.
Press “X,” “X,” “Left Bumper,” “Right Bumper,” “X,” and “X” to add “Clear System Cache” to the menu. This is not necessary if this option is already visible.
Select “Yes” on the confirmation prompt. A status bar will appear. The system cache will be cleared and the hard drive defragged when the process is complete.
Clearing the console system cache to defrag an Xbox 360 hard drive deletes all the previously downloaded game updates. You will need to re-update each game the first time it is played.
