iMac Intel 21.5" EMC 2389 SSD Dual Drive Installation Replacement

Trade your optical drive for a second hard drive.

There are many benefits to adding a second hard drive to your iMac such as improved speeds, greater storage space, and less heartache when installing new software. Use this guide to install one using our optical bay hard drive enclosure.

Edit Step 1 Glass Panel  ¶ 

  • Before beginning, unplug your iMac and lay it on a soft surface as shown.

  • Stick a suction cup near each of the two top corners of the glass panel.

  • To attach the suction cups we sell, first position the suction cup with the movable handle parallel to the face of the glass panel. While lightly holding the suction cup against the glass, raise the movable handle until it is parallel with the other handle.

  • If your suction cups refuse to stick, try cleaning both the glass panel and the suction cup with a mild solvent.

Edit Step 2  ¶ 

  • Gently lift the glass panel perpendicular to the face of the LCD enough to clear the steel mounting pins attached along the underside of the top edge of the glass panel.

  • Pull the glass panel away from the lower edge of the iMac and carefully set it aside.

  • During reinstallation, be sure to meticulously clean the inside of the glass panel and the face of the LCD as any dust or fingerprints trapped inside will be annoyingly visible when the machine is turned on.

Edit Step 3 Display  ¶ 

  • Remove the eight 8 mm T10 Torx screws securing the display to the outer case.

    • The last two pictures are detail shots of each side of the display.

Edit Step 4  ¶ 

  • Slightly lift the top edge of the display out of the outer case.

  • Do not lift it too much. There are several cables attaching the display to the logic board.

Edit Step 5  ¶ 

  • Pull the vertical sync cable connector out of its socket on the LED driver board near the top left corner of your iMac.

Edit Step 6  ¶ 

  • Rotate the display out of the outer case enough to disconnect the LED backlight power cable from the LED driver board.

  • Disconnect the LED backlight power cable by depressing the locking mechanism while pulling the connector away from its socket (toward the bottom edge of the iMac).

Edit Step 7  ¶ 

  • Grab the plastic pull tab secured to the display data cable lock and rotate it towards upwards.

  • Pull the display data cable straight out of its socket on the logic board.

  • Do not lift up on the display data cable, as its socket is very fragile. Pull the cable parallel to the face of the logic board.

Edit Step 8  ¶ 

  • Disconnect the LCD thermal sensor cable connector from its socket on the logic board.

  • If your fan is spinning full speed after completion, check this connection or the hard drive's thermal sensor cable.

Edit Step 9  ¶ 

  • Carefully pull the display toward the top edge of your iMac and lift it out of the outer case, minding any cables that may get caught.

Edit Step 10 Optical Drive  ¶ 

  • Remove the following four screws:

    • One 9.3 mm T10 Torx screw with a large head

    • Three 9.3 mm T10 Torx screws with a normal sized head

Edit Step 11  ¶ 

  • Pull the optical drive thermal sensor connector toward the top edge of the iMac to disconnect it from its socket on the logic board.

Image #1

Edit Step 12  ¶ 

  • Lift the inner edge of the optical drive and maneuver its connector past the GPU frame attached to the logic board.

  • Carefully pull the optical drive off its mounting pins on the right side of the outer case to gain clearance for disconnecting the optical drive cable.

  • Allow the optical drive to hang down as you de-route the optical drive thermal sensor connector from behind the GPU heat sink.

Edit Step 13  ¶ 

  • Disconnect the optical drive cable by pulling its connector away from the optical drive.

  • Remove the optical drive from the iMac.

  • Do not forget to also move the thermal sensor from the optical drive to the enclosure when you install the second hard drive.

Edit Step 14 Optical Drive Enclosure Faceplate  ¶ 

  • Remove the three 3.0 mm Phillips #0 screws from the optical bay enclosure.

Image #1

Edit Step 15  ¶ 

  • Starting from the left edge, gently pull open the optical bay enclosure.

  • Continue to pull open the two halves of the enclosure until they separate.

Image #1

Edit Step 16  ¶ 

  • Remove the two 3.0 mm Phillips #0 screws securing the faceplate to the optical bay enclosure.

Image #1

Edit Step 17  ¶ 

  • Lift the black plastic faceplate out of the optical bay enclosure.

    • You will no longer need the faceplate or the two Phillips screws that held it in place. Set those parts aside if you ever wish to put the faceplate back into the enclosure.

  • Reassemble the optical bay enclosure without the faceplate, reusing the original three 3.0 mm Phillips screws to keep it intact.

Edit Step 18 Dual Hard Drive  ¶ 

  • Remove the plastic positioner from the optical bay hard drive enclosure by pressing in on one of the clips on either side and lifting it up and out of the enclosure.

Image #1

Edit Step 19  ¶ 

  • Make sure that the hard drive connectors are facing down before placing it into the enclosure.

  • Gently place the hard drive into the enclosure's hard drive slot.

  • While firmly holding the enclosure in place with one hand, use your other hard to press the hard drive into the enclosure connectors.

Edit Step 20  ¶ 

  • Once the hard drive is snug, reinsert the plastic positioner while holding the hard drive against the bottom of the enclosure.

  • Reconnect any cables you have removed from the original optical drive onto the optical bay enclosure.

Im sorry to say, If it sparked when you touched it your motherboard s now fried. You need a new one.

Robert Wacker,

Do not try to pull the plug off the circuit board as it's soldered. Pull the cable sideways out of the socket.

Alex Campbell, · Reply

This cable is very short, I would remove it before any of the others. First time I did this, I didn't realize this and this cable just popped out of it's socket. Luckily, the board wasn't damaged.

i damaged my (step7) cable, and my iMac screen won't work, how to fix this?

Ersan Rasubala, · Reply

I did the same thing. The pins are VERY easy to bend. I replaced it with a new cable from this company.

Waiting for it to arrive.

Michael,

Hello, is the sata & power cabla from the mac can directly feet inside the SSD?

Roman Quenin, · Reply

plug in the back of the ssd

Roman Quenin,

I'm trying to find out as well. I read elsewhere you need something like this without the bracket: http://www.amazon.com/gp/product/B0056OB...

However I have NOT confirmed this.

Allen Borza,

Just curious, why is it necessary to remove this black plastic faceplate from the enclosure? It doesn't appear to serve any function in or out of the enclosure.

Nic Johnson, · Reply

Maybe because it would interfere with the bracket you have to put back on in step 21?

Jeff Dickson,

So I'm confused about the Optical Drive Bracket, the one that originally held the DVD-CD drive. I had an awful time remounting the kit into that bracket as the screws didn't line up correctly. I finally got everything to fit, less one of the four holding screws. Did anyone else experience this problem? I would have expected a much better alignment for this assembly considering the quality of the iFixIt site.

For the record, the upgrade went fine with a SanDisk Extreme II 480GB SSD, but that one step was next to impossible, and not covered in any detail by the instructions.
