HDD/SSD data recovery

It is a rather widespread problem: SD Card or HDD is not accessible, the type of the file system is RAW. At the same time Windows (7-10) gives notification “unable to run chkdsk on the disk”.

What is RAW, how bad is the problem for the hard drive (memory stick or memory card) and how to fix the error – read on.

A question from the reader:

"The hard disk stopped working. There is a suspicion that the reason is bad blocks, because earlier there were symptoms suggesting it. The problem is that I can’t boot Windows. How to create a bootable USB flash drive with HDD Regenerator program, if it is at all possible? Will it work like live cd?"

This guide describes basic principles of data recovery on HDD.
