Do you know what is data recovery? Here we will see its functions, working, factors and three main free data recovery software available on the internet.
Introduction
Data recovery(DR) is a process of retrieving lost, corrupted, damaged, or formatted data from secondary storage, removable media, or files. The term “data recovery” is also used in the context of forensic applications, where data that have been encrypted or hidden, rather than damaged, are recovered. Sometimes data present in the computer gets encrypted or hidden due to reasons like virus attacks.
Working
Data never gets permanently deleted, it’s possible to recover deleted files that has been erased from your computer’s memory or other storage devices. It is most often retrieved 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. It might have been lost due to physical damage to the storage devices or logical damage to the file system.There are chances of losing data in hard drives because of power failure and also sudden power surges can cause the computer’s hard drive to be damaged.
DR involves finding data and transforming it into a readable form, but all data may not be recoverable. DR can become so complicated if you overwrite on the storage medium that has the lost data.

Factors
The process of recovering data depends on factors such as the kind of storage device, the amount of damage done and also the kind of operation system used like Windows, Macintosh or linux.
DR becomes a very expensive process when taken to a DR center. If you are experienced in the field of computer, you could carry out the data recovery operations on your own computer, there are lots of software online that gets the job done at a lesser expense.
