I once encountered such a problem as recovering data from my computer.  and for a long time I was looking for a reason why it happened.  What methods did not try to resume their data and asked for help from friends and searched the Internet for video recovery lessons, but I could not wait long, I needed a computer to work.  And I was advised by an excellent company
