How do hard drives work? In this video tutorial Bill Hammack shows veritable miracles of modern science.

Maybe after this lesson in modern magnetic storage from Mr. Hammack you’ll appreciate how much more there is to storing your collection of House MD than simply printing ones and zeros on a shiny, spinning thing.

P.S. If due to a power surge you have accidentally burned your hard-drive PCB, please read this guide.
