A method for data storage implemented in a data storage system is disclosed. An array of bullet-firing barrels is arranged to project bullets in ah iron curtain under control of a fire control module that fires a round in a barrel above the projected flight path such that the round impacts the nose of the object and disables it. An actuating button is manually movable generally transverse to a longitudinal axis of the saw blade by the user between an engaged position and a disengaged position.
