Data recovery involves salvaging data from inaccessible, formatted, damaged, failed, or wrecked primary
storage media where data cannot be accessed normally using operating system. In case of data disasters, the data is being
salvaged from data storage media such as hard disk drive, pen drives, digital cards, storage tapes, CDs, DVDs, RAID and other
optical medias. This can be due to physical damage to the storage device or logical damage to the file system that prevents
it from being mounted by the host operating system. Although there is some confusion as to the term, data recovery can also
be the process of recovering deleted information from a storage media for forensic purposes.
