In computing, data recovery is a process of salvaging or retrieving inaccessible data – corrupted, damaged, or formatted – from secondary storage devices, removable media devices, etc. The data is retrieved from storage media devices such as hard disk drives (HDDs), solid-state drives (SSDs), USB flash drives, magnetic tapes, CDs, DVDs, RAID subsystems, etc. The data recovery can be done via data recovery software or by seeking the help of professional data recovery services. An excellent data recovery service ensures smooth recovery of all kinds of multimedia data, including text, images, audio files, and videos.
Some Common Data Loss Scenarios
- Failure of operating system
- Malfunction of storage device
- Logical failure of storage device
- Accidental damage or deletion of data
In any of the above scenarios, the best solution is to copy your files on another storage drive.
Scenarios that require Data Recovery Services
- Drive-level failure: Compromised drive partition or file system, or hard disk drive failure is a situation when you will require data recovery services. In such a scenario, you cannot correctly read the data. Resolutions involve repairing the file system, Master Boot Record (MBR) or partition table, drive recovery methods such as hardware and software recovery of corrupt service areas (also known as the firmware of hard disk drive), software-based recovery of damaged data, hardware replacement of physically damaged disk, etc. But if the drive has failed permanently, you should focus on one-time recovery — salvaging the data that’s still readable.
- Deletion of files from storage medium: In such a situation, the contents of deleted files are not removed from the drive immediately, but only the references to them in the directory gets removed. As a result, the space occupied by that data can be used for overwriting. Technically, data on original files do exist on the drive, often in a multitude of disconnected fragments, and can be recovered with the help of data recovery services.
- Physical damage: Physical damage to storage media can happen because of natural disasters or human errors. Situations of physical damage include the breaking of magnetic tapes, scratching off of the dye layer of a metallic substrate of CD/DVDs, mechanical failure of hard disks, like a motor failure or head crash, etc.
Common Devices used for data storage
- Hard disk drives
- Solid-state drives
- USB flash drives
- SD/Memory cards
- Digital cameras
- Backup drives
It is possible to salvage data from any of the given storage devices without much inconvenience.
Scope of Data Recovery Service
Data recovery service varies depending on the cause of data loss. Data may become inaccessible due to deletion or physical/logical damage to the storage media. Remote data recovery service is ideal in cases of logical damage, such as corrupt partitions, corrupt file systems, media errors, etc. of the storage media. In-Lab data recovery service is required when there is physical damage to storage media.
The four phases of data recovery service, for both physical and logical damages, include:
- Repair of hard disk drives
- Imaging drives to new drives or a disk image file
- Logical recovery of data files, partition, MBR (master boot record), and file system structures
- Repairing damaged files that have been retrieved
