  • Skip this step if your computer does not have an Airport card.

  • Firmly grasp the plastic tab attached to the Airport card and pull up and to the left.

  • Disconnect the antenna cable from the left side of the Airport card.

I'm not sure what the point is for this step. This helped not at all in getting the drive out. Also, the cable is taped down, and must be untaped before the card will come out.

  • Remove the two black plastic bumpers and two T8 Torx screws from the side of the hard drive.

It's best, when putting in the new drive, to screw the bumpers into the right side of the drive, then put the bumpers into the holes on the left side. Then, put the drive in in the reverse way you took it out: Left side first, then shove the bumpers into the holes on the right side. It's difficult, but it's the only way I could make it work. Then, of course, screw the left bumpers in the same way you unscrewed them.
