There is a lot of mythology surrounding the idea of data recovery. People have to go through it when they delete some important files by accident off their hard drives. Youll probably also see forum posts from people wondering what to do about their lost data after a computer crash. There are plenty of so-called experts on data recovery that would answer them, somewhat annoyingly, with: Did you make a back-up, Nope. And now your only history paper has gone down the tubes.
