The module which we were talking about before must also be removed and is held two extra Phillips screws (one longer than the other):

Finally, we have to remove the remaining two Torqx screws residing on the left side; then we can lift carefully the optical drive assembly, without touching any other components:

The SuperDrive has some components pre-attached which must be removed and re-mounted onto the Data Doubler; we are talking about the SATA Data + Power adapter and a small metallic adapter held with two black screws:

After removing the metallic piece from the optical drive, we can install it, along with the SATA connector, onto the Data Doubler:

Carefully, we will have then to slide the assembly into place, not to damage any data transmission wire:

We will fix then the Data Doubler with the two screws on the side, but not with the original ones, but the longer screws located into the package. These screws must not be tightened at first, because we'll see that the Data Doubler tends to lift on the opposite side and it will be a little hard to fix the third (and final) screw:

The third screw we mentioned earlier will be fixed with the help of the small metallic piece we have installed on the Data Doubler:

The final step would be to fix the rest of the data cables onto the motherboard:
