1. Turn off the Xbox 360 and stand it up right to where the hard drive is positioned on top.
2. Locate the hard drive release button toward the front of the hard drive, and push down.
3. The front of the hard drive should release, so pull up from the front to remove the hard drive.
4. When placing the hard drive back in, place the back side in first, then click down on the front.
