what is data recovery

1.Data recovery is the process of salvaging data from damaged, failed, wrecked or inaccessible primary storage media when it cannot be accessed normally. Often the data is being salvaged from storage media formats such as hard disk drive, storage tapes, CDs, DVDs, RAID, and other electronics. 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 in for example forensic purposes.

2.The salvaging of data stored on damaged media, such as magnetic disks and tapes. There are a number of software products that can help recover data damaged by a disk crash or virus. In addition, there are companies that specialize in data recovery. Of course, not all data is recoverable, but data recovery specialists can often restore a surprisingly high percentage of the data on damaged media.
