Set the drive in the plastic tray and align the drive ports with the tray socket.

To prevent strain on the enclosure socket, lay the drive as flat against the tray as possible.

Carefully push the drive into the tray socket to seat the ports.

Press the drive's raised edge down into the plastic tray.

If the drive edge catches on the foam block, the drive is not fully seated against the tray socket. Continue pressing the drive into the socket until it clears the foam block.
