Step 9

              Remove the HDD

Remove the three (3) torx screws from the HDD holder using a T8 torx bit.
These screws are self-tapping screws threaded directly into the plastic standoffs. Be careful while loosening and do not over-tighten them during re-assembly.
Fold back the shielding towards you.
Make sure you’ve disconnected the HDD ribon cable before you do this step.
Lift the HDD out of the case by tilting towards you.

Step 10

              Replace the HDD

Remove the 4 philips screws to release the HDD from the mounting brackets with a#1 Philips bit.
Set the rails asside.
You’ll notice that the location of the rail holes are non-standard for some newer IDE drives. Keep this in mind when purchasing a replacement!
Carefully loosen the ribbon cable from the drive with the point of a plastic Spudger by working it into a grove in between the connector and the drive.
Do NOT try to loosen the connector by applying force on the ribbon itself or near the soldier joints of the connector. This will rip the cable or damage the soldier joints.
