In computing, data recovery
is a process of salvaging inaccessible data from corrupted or damaged secondary
storage, removable media or files, when the data they store cannot be accessed
in a normal way. The data is most often salvaged from storage media such as
internal or external hard disk drives (HDDs), solid-state drives (SSDs), USB
flash drives, magnetic tapes, CDs, DVDs, RAID subsystems, and other electronic
devices. 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 by the
host operating system (OS).

The most common data recovery scenario involves an operating system
failure, malfunction of a storage device, accidental damage or deletion, etc.
(typically, on a single-drive, single-partition, single-OS system), in which
case the goal is simply to copy all wanted files to another drive
