In computer science, data recovery is an approach of recovering inaccessible, lost, corrupt, damaged or formatted data out of other external storage devices, removable media or even files. Data recovery can either be manual or automated, depending on the nature and extent of the damage. Generally, data recovery from physical media is very fast and simple as the physical media is usually intact. However, data recovery from a computer system is more complex as the computer system might be infected with a virus, firmware or even a program that overwrites the existing data. These viruses, firmware or programs are then responsible for altering the computer configuration settings which, in turn, deny the computer access to files and programs. Hence, to retrieve the data, the user needs to do some extensive computer research before he can actually attempt data recovery.
It must be kept in mind that data recovery from computer storage media depends primarily on the cause of the damage. One may have deleted a file, but if the file still exists it can be easily retrieved by a good data recovery software. If the user can restore a previous state of the file to its previous state, then he can make use of this data recovery technique. On the other hand, if the file’s overwritten by some new program, then it will definitely be very difficult for him to recover it. However, if you can restore the state of the file that was previously deleted, then it can be very easy to retrieve data that was lost due to overwriting.

One important point that must be kept in mind is that if a person is serious about data recovery, he should buy a good data recovery software that can recover files that have been accidentally overwritten by a virus, firmware or another program that came along with the original computer. It is very easy to retrieve files that have been deleted by a virus or a program installed on the computer. The problem lies in trying to recover files that have been lost due to overwriting, as both these situations cannot be restored back to its original state.
The first thing that must be done after losing any file is to check whether the drive has written over it or not. If the drive has written over the data, then it could be possible that you can recover them with a good data recovery software. This is the first step towards data recovery. The other thing that can be done is to try and find out whether the hard drive had written over the lost data using a different drive.
Once you are sure that the drive has written over the lost data, then all that remains is to look at the actual location where the deleted data is being lost. You need to make use of a good data recovery software in this stage. A good recovery software can recover all types of deleted files and especially, can recover data from a damaged disk or an SD card. In addition, with the help of a good recovery software, it is also possible to recover data from a virus attack.
Once the data has been restored, it is necessary that you save all the restored data onto a removable disk in order to avoid overwriting it again. If you do not do so, your search for your lost contacts may end up being more frustrating than fruitful. You can even recover deleted emails, but for that you will have to get a data backup of the email. Once you have made sure that the backup is working fine, you can start off with the recovery process. When the recovery process is over, you should be able to access all your contacts easily.
