Data recovery refers to the recovery of data on a computer that has been lost due any potential reason.

While these utilities help repair minor inconsistencies, they're quite useless in the event of large scale data loss. There are third party utilities available, some of which are far superior to these built-in utilities on these operating systems. These third party utilities can even recover data from disks that are not recognized by the operating systems? own repair utility. Data recovery tools use two main techniques to achieve the desired results.
