Peel the aluminum tape off of each side of the drive, it is easy to tear but with the new drive I am working on, the glue isn't very strong, so you should be able to remove it fairly easily.

This tape is used to protect from noise by shielding it, it is not strictly necessary if you wanted to use this board with a different drive but its there, so I decided to leave mine on the board.

The picture is of what it should look like after you remove the tape from the drive.
