While the information stored in the disk is stored in the "analog" world (magnetic potential of parts of the platters), there's an infinite amount of states that lead to the same digital disk contents. You can't take the digital representation and reconstruct the analog state that leads to it, since by doing the analog-to-digital conversion there was information loss. And growing a body with a "blank" brain, what does that mean? Your conscience is absolutely intertwined with your body. If you take my mind and put it in Usain Bolt's body, that Frankenthing won't run 100m in <10s.
