After removing the hard drive assembly from the frame, remove the four 3-mm M3 Phillips screws.

Once the screws are removed, remove the hard drive from the hard drive frame.

When re-mounting the hard drive into the hard drive frame, be sure to install the hard drive so that the underside of the hard drive is on the side of the frame with the tab. Also, make sure to put the Sata ports on the side opposite the tab so that they are not covered.
