Data Recovery is the process of salvaging data from damaged, failed, corrupted, or inaccessible secondary storage media when it cannot be accessed normally. Often the data are being salvaged from storage media such as internal or external hard disk drives, solid-
The most common “Data Recovery” scenario involves an operating system failure (typically on a single-
Another scenario involves a disk-
In a third scenario, files have been “deleted” from a storage medium. Typically, the contents of deleted files are not removed immediately from the drive; instead, references to them in the directory structure are removed, and the space they occupy is made available for later overwriting. In the meantime, the original file contents remain, often in a number of disconnected fragments, and may be recoverable.
The term “data recovery” is also used in the context of forensic applications or espionage, where data which has been encrypted or hidden, rather than damaged, is recovered.
Physical damage
A wide variety of failures can cause physical damage to storage media. CD-
Most physical damage cannot be repaired by end users. For example, opening a hard disk drive in a normal environment can allow airborne dust to settle on the platter and become caught between the platter and the read/write head, causing new head crashes that further damage the platter and thus compromise the recovery process. Furthermore, end users generally do not have the hardware or technical expertise required to make these repairs. Consequently, data recovery companies are often employed to salvage important data with the more reputable ones using class 100, dust-
Recovery techniques
Recovering data from physically damaged hardware can involve multiple techniques. Some damage can be repaired by replacing parts in the hard disk. This alone may make the disk usable, but there may still be logical damage. A specialized disk-
Hardware Repair
Media that has suffered a catastrophic electronic failure requires data recovery in order to salvage its contents.
A common misconception is that a damaged printed circuit board (PCB) may be replaced during recovery procedures by an identical PCB from a healthy drive. While this may work in rare circumstances on hard drives manufactured before 2003, it will not work on newer hard drives. Each hard drive has what is called a System Area. This portion of the drive, which is not accessible to the end user, contains adaptive data that helps the drive operate within normal parameters. One function of the System Area is to log defective sectors within the drive; essentially telling the hard drive where it can and cannot write data. The sector lists are also stored on various chips attached to the PCB, and they are unique to each hard drive. If the data on the PCB does not match what is stored on the platter, then the drive will not calibrate properly. In most cases the hard drive heads will click, because they are unable to find the data matching what is stored on the PCB.
Four phases
It is important to understand the four phases of data recovery. Each phase stands for different level and range of data recovery capabilities, each phase requires different hdd repair tools and data recovery tools to work with and each phase must be treated properly to make sure the maximum data is finally to be recovered.
- Phase 1: Repair the hard drive
- Phase 2: Image the drive to a new drive.
- Phase 3: Logical recovery of files, partition, MBR, and MFT.
- Phase 4: Repair the damaged files that were retrieved.
