This repair will need:
A T8 Torx screwdriver.
After completing the initial disassembly, you may proceed to hard drive replacement.
First, you will need to remove the five T8 torx screws that mount the hard drive to the internal frame.
Next, you will remove the mounting frame and the plastic shield.
You can use a spudger (tool shown in photo) to remove the ribbon cable from the hard drive.
Carefully, pry the ribbon away from the pins.
Attach the ribbon cable to the new hard drive and follow steps 1-3, in reverse, to complete the installation.
