        1. Hi Johnson,

          I’d suggest you to take out the drive and connect it externally on another working PC. Download and install our software named ‘Stellar Windows Data Recovery Pro’ and select the problem drive from ‘Drive Recovery’ option and select suitable recovery methods like Advanced Recovery. You’ll be able to see preview of recoverable files and folders before actual recovery.
