Researches say that out of the many different reasons of data deletion, the most common cause is human mistake. Sometimes, it happens accidentally, whereas some other time, it is intentional. You were deleting some unwanted copies of photos, when mistakenly deleted the only copy of a memorable photograph. Similarly, you just deleted a folder and only after the deletion, realized that there was one important financial document in that deleted folder, which you need badly. While working on your LINUX system, such instances are not so uncommon and users do encounter them quite often. But, don’t worry! Even after such critical cases of data loss, you can still recover your data by using any good Linux data recovery software.
There are various instances of data deletion, including accidental deletion, intentional deletion of data or sabotage, deletion by virus attack etc. In earlier time, it was believed that once you deleted a data from the system, the data goes for ever and it can never be retrieved. But, one interesting truth regarding this myth is that recovery of a deleted piece of data is quite possible.
So, the question is what happens to the data that you deleted and how it can be recovered back? When you deleted a file from your LINUX system, the operating system removed all its entries from the system hard drive and marked the memory, allocated to the deleted data as free. But, remember that LINUX does not erase or overwrite the deleted data, until you save new files onto the same disk. Hence, if by any technique you can find out the removed entries of the deleted data and read them, the data can be recovered.
The LINUX recovery software do exactly the same. These software are developed with highly advanced scanning algorithms. When you run the software, these scanning algorithms dig your hard drive/volume in all possible ways and read the lost/removed entries. By using those lost entries, the software recovers the deleted or formatted data back.
These Linux data recovery software are absolutely read-only in their operations and never alter the structure or format of the data in the drive. Moreover, the utilities are developed with such user friendly user interfaces that they can be used by professional programmers as well as non-technical home users.
