Instructions
Power down your Xbox 360 video game system.
Turn your Xbox on its side, so the HDD is facing upward.
Press down on the current HDD's release button, located on the side closest to the Xbox's front, then lift up to remove the drive from the Xbox.
Place the back end of the new HDD into the Xbox's hard drive bay.
Lower and push the front of the HDD into the hard drive bay until you hear a click. This is the release button locking the replacement hard drive into place. It is now ready for use.
