But of trivia about the first IBM hard drive: the heads weighed about 8g each and were glued to the actuator arms. The platters needed periodic cleaning, but the cleaning agent dissolved the glue holding the heads. The heads would break free from the arms and adhere to the platter. The rotation speed would accelerate the head outward, and the head would exit the housing with the approximate kinetic energy of a 9mm bullet.
