Data Recovery involves recovering data from damaged, failed, corrupted, or inaccessible storage devices when they cannot be accessed through traditional methods.

Recovery may be required due to physical damage to the storage device or logical damage to the file system that prevents it from being mounted and accessed.

The most common situation involves a failure that prevents the operating system from booting, in which case the goal is simply to copy important files to a working disk.

Data Recovery can be very difficult depending on the situation, solutions involve repairing the file system, partition table, master boot record or hard disk recovery techniques ranging from software-based recovery of corrupted data to hardware replacement or failed components.
