I just did this upgrade and my HDD was secured with screws on both sides of the caddy. I actually think the caddy is really only designed to hold a single drive, kind of in the middle position, i.e., it's not the upper, or 2nd drive, position. In any case, this requires removal of the logic board, power supply, and caddy, entirely, in order to remove the existing drive. Tedious, but I didn't have any problems on reassembly.
