chapter20, How is data recovery in the world?

Today, we would like to introduce a “mysterious” data recovery in Japan.

1, Magnetic head map switching:
Anyway, this is it! Is this often done to recover data from a drive with damaged magnetic heads? Of course, there is no reason to recover the data because by this way, and it seems that the drive is returned to the client as it is.

On this background, there seems to be a machine that can do this. However, it should be impossible to connect customer’s drive without any basis.
