For many years data recovery simply referred to the process of rescuing files and digital information from failed hard drives. In fact, when drives were larger in size but smaller in volume data recovery companies often repair the drive that data was lost on. Today hard disks can accommodate a terabyte in storage on a drive that is one quarter the physical size of its 1991 counterpart. Physical damage is far less of a problem then file corruption leading to a system failure. Also, newer hard drives simply do not fail as often. With all of this said data recovery has shifted to specific areas such as photo recovery, and file recovery from other solid-state digital media.
