In information technology, data recovery is basically a procedure of recovering permanently lost, inaccessible, corrupt, damaged or Format data from removable media, primary storage or files, especially when the data found in them can not be accessed in an ordinary manner. Data recovery can also be done on a computer. This can be done to retrieve lost information from a system which has been deleted, accidentally modified or lost. It can also be done to retrieve information from a computer that has been infected by viruses or Trojans. Learn more details now.

Data recovery techniques run on different operating systems like Windows, Mac OS and Novell. The techniques used to retrieve data may differ, depending on the nature and location of the data that needs to be recovered. For instance, if a document that contains the name of a company employee is lost and his exact account number is lost, the best way to retrieve such information is to make a back up of the folder structure of the computer hard disk. When one makes a backup of the folder structure, the data recovery techniques run first on such disk and the data they recover becomes retrievable. However, it is often necessary to make changes in the system registry before running any data recovery techniques.

​

Data retrieval methods are broadly categorized into two categories, namely, file recovery and hard drive recovery. In case of file data recovery, the data recovered can be moved from one physical location of the hard drive. For flash drives data recovery, such data recovery may include the extraction of the data in the internal memory of the flash drives. However, it depends on the nature and location of the data that needs to be recovered. All of your question about this service will be answered when you follow the link.

File recovery methods are commonly initiated by the owner of the system. This is done by overwriting, which is a procedure of overwriting the data on the affected physical area. It is essential that one does not perform overwriting if the files are formatted. This causes irrevocable damage to the affected drive and may make it impossible for file recovery software to locate and reinstate the files.

​

One may also opt for data recovery services, when one accidentally deletes or overwrites some of the files. There are some companies that offer services for recovering deleted files. This is sometimes a difficult task because of the difference in format and size of the file. These companies have special equipment to avoid damage to the hard disk while performing the overwriting process. Such companies do charge a nominal fee for the service. Seek more info at https://en.wikipedia.org/wiki/Data_recovery.

The meta data is saved in the form of folders, and hence one has to follow certain steps to look for the lost data.
