How to Install a Second Drive in Your 13” Mid-2012 MacBook Pro

Data_doubler_installed_gall4You might find yourself using the optical drive in your 2012 MacBook Pro less and less. Or maybe the optical drive no longer works, and you would rather have more internal storage than replace it.

With the OWC Data Doubler, it’s possible to add up to 2.0TB of internal storage to your MacBook Pro. Or you can add an OWC SSD for speedy boot and app loading times.

The Data Doubler is a custom engineered anodized aluminum bracket with that fits perfectly in your MacBook Pro’s optical bay and is ready to mount your 2.5” HDD or SSD. It also comes with all the tools needed for installation.

With OWC’s DIY Data Doubler kit and installation video (below), you’ll open a new world of possibilities for your 13” non-Retina 2012 MacBook Pro9,2. (Note: It is highly recommended that you backup your data before installing Data Doubler.)

If you are unable to watch the video above, or would like to see a quick guide on installing the Data Doubler, we have put together a step-by-step guide below for replacing your 2012 MacBook Pro’s optical drive with an OWC Data Doubler. (Note: The 2012 MacBook Pro’s optical bay cannot reliably support SATA 6Gb/s SSDs and HDDs. However, SATA 3Gb/s SSDs and HDDs will work without issue in the optical bay. If you’re installing a SATA 6Gb/s drive with your Data Doubler, it is recommended that you install the 6Gb/s drive in the main drive bay and use the Data Doubler to install the stock 3Gb/s drive in the optical bay.)

Step 1) Open Your MacBook Pro
Discharge static electricity and then turn off your MacBook Pro and place it on a soft static free surface. Use a Phillips screwdriver to open the bottom plate of your MacBook Pro and set the screws safely aside.

Step 2) Disconnect Battery & Data Cables
Set aside the MacBook Pro’s bottom casing and use a nylon tool to gently disconnect the battery connector from the logic board. Then use the nylon tool to disconnect the three data cables.

Step 3) Remove the Optical Drive
Remove the three screws that hold the Data Doubler in place. Note: To access the second screw in the top left corner, you will need to loosen the module that is held down by three screws seen in the second image below. You can then remove the second and third optical drive screws on the left side. Then use your nylon pry tool to gently lift the drive from the bay.

Step 4) Remove SATA Connector & Mounting Bracket
Gently pull out the SATA connector and unscrew the mounting bracket from the optical drive.

Step 5) Install the Drive into the Data Doubler
Install the new HDD or SSD into the Data Doubler with the included screws. Next, slide in the SATA connector that you removed from the optical drive and attach the mounting bracket to the Data Doubler using the screws that held it to the optical drive.

Step 6) Install the Data Doubler
Carefully slide the Data Doubler in to place and use the original screw on the right side of the Data Doubler. Then use the two included longer OWC screws on the left side of the Data Doubler. Once that is done, reinstall the module above the Data Doubler with the original three screws.

Step 7) Re-assemble the MacBook Pro
Follow the original steps in reverse order to re-assemble your MacBook Pro and connect all cables and the battery. You may now flip your MacBook over and turn it on.
