Data Salvaging Made Very Easy Data recovery is defined as the procedure of recovering data from wrecked, failed, damaged or inaccessible primary storage media when it cannot be accessed by the regular process. Damage may be the result of physical damage to the storage device or logical damage to the file system that prevents it from being accessed by the host operating system. Usually the data recovery is salvaged from storage media, like storage tapes, hard disk drives, CDs, RAID, DVDs, and other devices.
