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.
After you lift off the hard drive casing, using your Phillips #000 Screwdriver, remove the two 3.6mm screws located on the right side of the hard drive.
Using your fingers, carefully lift the lower right corner of your hard drive until it is removed from its housing.
