Instructions
Power off the console. Locate the hard drive, which is attached to the right of the disc tray when the console sits horizontally.
Press the gray button on the hard drive and hold it down. The hard drive will give way a little but won't fully detach.
Grip the sides of the larger portion on the hard drive, then pull it off of the console.
Position the new hard drive over the vacant hard drive bay.
Grip the larger end of the hard drive and push it down as far as it will go.
Push down on the other end until the gray button clicks, indicating the hard drive is locked into place.
