Hard drives consist of a stack of spinning “platters”, with a set of “read heads” on an arm that flies over the surface of the disk to find the data that’s being read or written.
Describing this is all well and good, but really you get a much better feel for this if you actually see it for yourself. So, this morning we took an 8-year-old 500GB drive that died recently and took it apart. DOING THIS KILLS THE DRIVE! Ours was already dead so we had nothing to lose 🙂
For this job we needed a screwdriver with a six-pointer star shaped head, known as a Torx head. Everything inside used the same screwdriver, specifically size T8.
