ELI5: How does a busted hard drive that won’t boot anymore get its data recovered when you take it to the magic computer repair shop?

There are some tricks to it. If you only lost your MBR, the drive can be dropped into another machine and the data recovered. 

If the drive is truly dead, as in it does not spin, it can be sent into a shop that will remove the platters and place them into an identical drive and then recover the data. That method is expensive and takes a while.
