A specialized disk-imaging course of action is accustomed to recover each individual readable bit within the surface. When this picture is obtained and saved on a trusted medium, the image might be properly analyzed for sensible problems and will potentially allow Significantly of the original file system for being reconstructed. Components restore[edit]
