• Data Recovery

Data recovery is a process of salvaging (retrieving) inaccessible, lost, corrupted, damaged or formatted data from secondary storage, removable media or files, when the data stored in them cannot be accessed in the usual 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 devices or logical damage to the file system that prevents it from being mounted by the host operating system (OS).

External or internal hard disk drives, solid-state drives, CDs, DVDs, USB flash drives, and other electronic devices data are often recovered from storage media through this process.

 

It is usually required when the storage files are physically damaged. It also occurs if the document’s framework’s logically damaged which prevents the data from being accumulated by the host OS.

 

 

• Data Recovery Techniques

These techniques are based on the type of damage that occurs in the storage. It solves recovery issues of recycle bin, formatted file, raw, and hard drive lost data. These techniques are categorized into logical and physical.

Logical refers to the improvement of an error that is not associated with hardware and only is solved by using a software solution. In logical damage cases, corruption of hard disk and inaccessibility of drive occurs due to the deleting, damaging, overwriting, and formatting of the hard disk. This loss is only be solved by operating logical data recovery.

Physical usually helps to solve the physical damage which occurs due to human errors. Hard drives are complex and a minute shock can result in permanent data loss or non-functioning. To avoid the risk of physical damage, it’s necessary to handle the hard drive gently with utmost care.

It also deals with the revival of hidden data. Encrypted data, rather than the deleted data, is also recovered by some forensic computer experts. Recovery experts do not always need physical access to the software for recovering the data; they can also easily do it by using remote access software over the Internet.

Hardware data recovery can be expensive because technicians may need to disassemble your hard drive to recover the data. Hard drive data recovery is usually done in a 'clean room' as hard drives are sealed to avoid errors caused by dust or other particles. Also, hard drives are finely tuned machinery and it takes specialist equipment to read the platters from a physically damaged drive.

3. It can bring the user’s pictures and files back that is precious and important to them.
4. Data recovery also serves as an additional storage device for companies.
5. Important in a way that the user’s data is secured after any virus attack or damaging of the software.
