Flip your computer over, so that the underside of your computer is facing upward.

Make sure your computer is powered down and unplugged from the charger before removing any components.

Locate the hard drive casing on the bottom-right corner of your flipped computer.

Remove the two 3.8mm screws with your Phillips #00 Screwdriver and carefully lift up and remove the hard drive casing.

Screws on hard drive casing will remain in casing after being unscrewed.
