type of HDD crash

There are two ways that drives crash:

1. Logical failure
2. Mechanical failure.

In a logical failure, the drive’s components are physically undamaged, but because of either accidental formatting or a corrupt file system, the drive is not able to find and navigate its own data. However, unless it has been overwritten, that data still exists on your drive.

And your point would be ... ?

Are you going to offer a solution to HDD crashes? A recommendation on how to recover from one or maybe avoid one?
