What is Data Recovery?

Date Recovery is the process of restoring data that has been lost, accidently deleted, corrupted or made inaccessible for any reason from a hard drive, removable disk, or other type of electronic storage media when the data cannot be accessed via normal means.

What is the Principle of Data Recovery?

When we deleted a file, in fact, it just modifies the first two bytes in the file header of this file. And the modifying will be mapped to the FAT of this file, and a deleted tag also will be added to the file so that we can't see this file any more. So it means that this file is still stored in our disk.

However, once some new files have been written to the hard disk, they will cover the original position that the deleted file occupy. At this moment, the deleted files can't be restored any more. Apart from this situation, normally you can get deleted files back.

Therefore, the principle of data recovery is searching and analyzing the file header in the disk to find out the files that have been marked, and then try to rewrite the two codes.

We can draw two conclusions from the principle of personal information , one is that the deleted files can be recovered only if its space is not be covered by other files, another one is that we can't delete files completely with common deleting methods. It means that we need to some cleaning software to eliminate data recovery  to ensure privacy, for example, PhoneClean is a fantastic cleaning software for iPhone, with it you can deleted personal data, junk files, etc.

In all, know more about data recovery so that you can judge whether your lost or deleted data can be recovered or not, and deleted personal data completely to keep your privacy at the same time.
