I started to think the drive was missing b/c my model is just -1204, not the 1204X version. But then I looked again at the pics above. There is NO DRIVE in their pics either! Not until steps 7-8 where you can see they layed one in there. Steps 3,4,5&6... There Is NO drive so why would you be taking the battery out? Even if there WAS a drive in this model, unnecessary manipulation of a lithium battery is not a wise move.
