Create an image at the first sign of storage failure. If you notice that your storage device is starting to fail, you should immediately create a backup image of the medium so that you can attempt data recovery later. That way, you can preserve whatever information is currently on the drive before it incurs further data loss.
Data recovery software often saves recovered files in a specified directory which you can then access through Windows File Explorer. Disk Drill, for example, is one of the best data recovery programs around and includes a button at the end of the retrieval process that will open the folder where your recovered MPA files are located.
