In information technology, data recovery is basically a procedure of recovering, restoring, formatting or otherwise recovering permanently lost, inaccessible, formatted or corrupt data from secondary storage devices, such as floppy disks, memory cards, hard drives and other removable media. Data recovery is therefore also referred to as file recovery. Data loss can result from a number of situations, including accidental deletion or damage to the storage media, system crash, power failure, data corruption, viruses, human error and many other reasons. Data loss can also be caused by deliberate actions of an individual. Regardless of the cause of data loss, it is very important that the information can be recovered.

Data recovery techniques allow users to recover deleted or accidentally deleted files. They are used for a wide range of purposes, ranging from data recovery of logical files and application files, to the reconstruction of a virtual machine and installation of applications and components. It is for these reasons that this service is also known as file restoration or backup service.
The procedure involved in data recovery depends on the nature of the data loss. In case of accidental deletion, the recovery process is quite simple. Data recovery software programs enable recovering most of the information from an accidentally deleted file, including program history, saved passwords, settings, system files and any other data that may still be present in the storage media. In case of a hard disk drive failure, recovery becomes more difficult.
In case of a failed hard drive recovery, the first step is to check the integrity of the drive. If the drive is not readable due to physical damage, then you need to make use of specialized data recovery software. There are two ways to perform recovery using recovery software – one is to make use of the ‘checksum’ method and the other is to use the ‘partition table’. The checksum method requires you to reconstruct the lost data by checking the changes that have been made to the logical structure of the drive. This is possible through the aid of specialised repair tools. Once the changes to the logical structure of the drive are identified, you can determine which file has been overwritten and thus recover it.
While performing the recovery process on a logical computer system, you need to follow some specific procedures in order to ensure correct functioning of the device. For example, in the case of operating systems such as Windows, the booting processes use sector transfers to load the operating system from the storage device. To access the boot management program, you need to boot the machine using the OS CD.
When performing recovery on a physical disk, you need to open the CD containing the recovery software. Use the arrow buttons to browse to the section named FAT32 which lists all the files that are contained on the selected disk. After you have identified the file, you can delete the file by pressing the ‘Delete’ key on your keyboard.
