Hard drive recovery is the process of recovering data and restoring a hard drive to its last known good configuration, after a system/hard drive crashes or is corrupted/damaged.
It enables a hard drive to recover from a temporary failure and restore it to normal working condition along with data that was deleted, lost or inaccessible.
Hard drive recovery is generally performed through hard drive recovery software. Logical errors such as accidental deletion and data corruption can be fixed by using hard drive recovery software that can extract all data, except where it has been overwritten in the disk sector.
Hard drive recovery can also be performed manually by connecting the hard drive to another computer using a SATA, ATA or USB interface. Moreover, hard drive recovery also involves recovering and copying data from dead drives and repairing physical damage to a hard drive.
Hard drive recovery for physically damaged drives requires repairing and replacing faulty component(s)/part(s). In this scenario, the data is not deleted or corrupted but requires the hard disk to be in physically operational form before data can be accessed from it.
