"Data recovery experts are the technological doctors and nurses of desktop or laptop hard drives" according to the BBC.
In so far as the 21st century is concerned, the transfer of attributes between computers and humans has been mutual. In the UK, it is not only the people who are susceptible to the consequences of a highly digitised culture; computers are also acquiring personal traits of their own. This intense humanisation of digital devices is not restricted merely to the production line. People owning them also tend to share an intense relationship with them. Computers have redefined the concept of personal space, which has shrunk to the level of being a subset of cyber space. This mutual cohabitation exposes the computers to human foibles and weaknesses, the consequences of which may sometimes be disastrous. Like humans, computers are also prone to accidents and data disasters due to reasons which are sometimes technological or are the result of human negligence and rage. Although computer malfunction remains the number one cause for data losses in the UK, human error seems to be a growing problem. Laptop computers are especially likely to get damaged with people leaving them on buses, gardens, and pubs.
Herein comes the role of data recovery. Poetically, it may be defined as an attempt to rescue a computer’s soul. Technically, it stands for restoring data from disks, tapes, CDs and digital memory cards that have been damaged by accidents, natural disasters, power surges and malfunctioning electronics. Data may sometimes be accidentally deleted and lost. However, once a file is deleted, that data still remains intact in the hard drive. The Operating System simply enters the file as deleted in the File Allocation Table (FAT) and conveys to the Operating System that the space allocated to the file is available for writing. This space is then marked as free space and new data may be written on it. Before this space is occupied by a new file i.e. before the deleted file is overwritten, the data is intact and recoverable. However, once the file is overwritten, the process of data recovery becomes cumbersome. If the data is lost due to other reasons like physical or logical damage, data recovery is possible. Physical damage to the storage media can occur due to a number of reasons involving mechanical and electronic failures and inevitably results in some data loss. Logical damage may occur due to power disruption, electrostatic discharge (ESD), etc, that may prevent the file from being completely written to the storage medium. The result is that the file system is left in an inconsistent state. Various programmes are available to correct these inconsistencies and most operating systems come with at least a basic repair tool for their native systems.
Physical or logical damage of media is mostly irreparable by the shelf users. It needs Class 100 Clean Room facilities and technical expertise. Hence the data recovery specialists are required to handle such a delicate task. Two main approaches are followed by data recovery technicians. First involves scanning the logical structure of the disk to ensure that it is consistent with its specifications. The second approach for file systems repair is to assume very little about the state of the file system to be analysed and using any hints that any undamaged file systems may provide, rebuild the file system from scratch. Lost data is not one hundred percent recoverable but data recovery technicians can often recover a surprisingly high percentage of data from the damaged media. The process of data recovery is becoming increasingly difficult. The disk drives being manufactured now have the parameters unique to them stored on them at the time of manufacture. If the drive gets damaged in the areas containing the drive information, it may not be possible to repair them by simply replacing the parts.
In the UK, there are a number of concerns offering data recovery services, targeting businesses and individuals who have a high demand for their lost data.
