None of the above correctly describes how to open the My Book Studio LX. The 2 TB Version has P/N WBDACH0020HAL-00. The case is silver colored aluminum, there are no visable screws, and two thin rubber feet on the bottom of the case, which should be left attached, as they are rubber-cemented in place, and do not cover any screws. The rear panel has a power jack, a mini-USB 2.0 port, 2 FireWire 800 ports, a security slot, and a power button. The case cover is held in place by spring clips located on each side of the back spine of the drive. To open the drive, a spudger should be inserted in the curved slot at the front top and bottom of the drive. Spread the gap open carefully, and the spring clips should give way, allowing the cover to move forward to remove. Screwdrivers could also be used, with the risk of scratching the aluminum. Trying to open along the rear spine will only dislodge the rivited spring clips and damage the case, so work at spreading the front top and bottom areas.
