Data recovery services are used when important data is no longer readable and cannot be recovered through the use of data recovery software.

Data recovery refers to the process of accessing and recovering damaged, lost, corrupted, damaged, or formatted data from digital storage devices. In most cases, the data to be salvaged is on internal or external hard disk drives, solid-state drives, USB flash drives, RAID arrays, CDs, DVDs, or other devices, such as cameras or mobile phones.

Commonly, the originating problem is an operating system failure, device malfunction, logical failures, or accidental damage or deletion of files, most often on a single-drive computer with one operating system, in which case the data recovery service would attempt to access the files, copying them from the damaged media to a new drive.

In some cases, this can be accomplished through the use of a Live CD, booting the system directly from a ROM rather than from the corrupted drive, with a facility to mount the system drive and move the files to a backup media using optical disc authoring software or a file manager. Sometimes, disk partitioning is used to store valuable data on a different partition from the operating system files, which are easily replaceable.

In the event of a drive-level failure, where a file system or drive partition is compromised, the data is not easily read by media devices. Depending on the specific nature of the problem, this might require the repair of the logical file system, partition table, or master boot record, or other drive recovery techniques, which may include software-based recovery of corrupted data, the recovery of damaged service areas through a combination of software- and hardware-based techniques, or hardware replacement of a physically damaged drive that allows for the extraction of data to a new drive. When the drive itself has failed permanently, the focus is on a one-time recovery, in which as much data as possible is salvaged.

When files have been accidentally deleted, references to the files are removed from the directory structure, but the contents of the files are not immediately removed from the drive. The deleted data may still reside on the physical drive, often in disconnected fragments, and may be recoverable if they haven't been overwritten by other data files.

In some cases, a knowledgeable end-user might be able to recover data using data recovery software. In doing so, however, there is a danger that the data may be further damaged. For this reason, individuals and companies experiencing the loss of important data often employ the services of a data recovery company rather than attempting to retrieve the data in-house.

The data recovery service generally has a larger array of tools, which may include advanced software tools as well as the necessary hardware to retrieve data that is salvageable. Depending on locations, some data recovery services will send technicians to the location, while others will ask that the drive be shipped to their location so that the tasks may be handled at their facilities, which is better equipped.
