Guys hold up a min. Before you call Dell, make sure the secondary caddy isn't n your system already. Mine, as most have, actually ship with the secondary caddy installed already. When you pull the secondary cady out, it will have a piece of foam with the screws and interposer in it, taped to the inside of the caddy. All you have to do is turn the laptop over, remove the battery, remove the bottom plate with the nametag (two screws) and you can see the HDD caddys. Your primary is labeled HDD 0. The secondary is labeled HDD 1. All you have to do is remove the caddy (4 screws) and turn it over to get the foam with the additional parts. Insert new HDD into the caddy, use the four additional screws to attach the caddy to the HDD. Then slide the interposer onto the end of the HDD, and screw the caddy into the M17x. Re-attach base plate, install battery and your done.
You can also check out this service manual for instructions on how to get to the HDD Caddy. It even has pictures
