Data recovery is a process which restores damaged files or data that are not accessible to a usable condition. This can be accomplished by different methods, including specialized software, hardware and laboratory methods on physical recording media. A proper approach and timely application are the key to a successful recovery. In most instances, data may be recovered even when a hard drive is physically damaged.

The most important stage in the process is backup, which should be conducted regularly. This will enable you to quickly recover your data in the event of a disaster. Do-it-yourself recovery techniques are not recommended. A mistake at home repair can harm the files and make it more difficult for professional recovery efforts.

Many files can be found with a program that searches for signatures on files. These are patterns that signify the specific file type. For see page example PNG files begin with the string ‘%0PNG.’ MP3 files start with the string ‘ID3.’ This method works best when the original files haven’t been modified and are in good condition.

Data recovery techniques that are more sophisticated make use of the structure of files to locate data that has been hidden by damaged areas on a hard drive. This can involve data carving, which makes use of the knowledge of file structures to retrieve fragments from missing or damaged files. The final step involves the restoration of files and folders to their working condition usually using an exact copy of the original data in order to prevent further damage.
