  2. Data Recovery • Data recovery is a process of salvaging inaccessible data from damaged or corrupted secondary storage , when the data 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), USB flash drives , solid-state drives (SSDs), magnetic tapes, CDs, DVDs, and other electronic devices.

  3. Physical Damage • A variety of failures can cause the physical damage to the storage media. The failures may be the result from human error or natural disasters. • For example hard disk may suffer mechanical failures such as head crashes. • Physical damage always cause atleast some data loss.

  4. Recovery Techniques • Recovery process involves multiple techniques • Some damage can be repaired by replacing part in the hard disk but logical damage may occur. • A specialized disk-imaging procedure is used to recover every readable bit from the surface.

  5. Logical Damage • In logical damage situation, error is not a problem in hardware but It requires software level solutions. • The logical errors are Corrupt partitions and file systems, media errors and overwritten data.

  6. Remote Data Recovery • Data recovery experts always do not need to have physical access to the damaged hardware. They can use the software techniques to recover data. • They can perform the recovery using remote access software over the internet.

  7. Phases of data recovery There are four phases in data recovery • Phase 1 : Repair the hard disk drive • Phase 2 : Image the drive to a new drive or a disk image file • Phase 3 : Logical recovery of files, partition, MBR and MFT • Phase 4 : Repair damaged files that were retrieved
