Disconnect the orange hard drive ribbon cable from the logic board.

Remove tape as necessary and use a spudger (or carefully push a credit card under the tape) to carefully loosen the adhesive securing the sleep light and IR sensor connectors to the top of the hard drive.

You may find it best to loosen the left edge, then the right edge, then the center of the tape to attack it from all points, so as to gently apply force to the smallest possible sticky surface.
