With the artificial intelligence we must communicate very carefully because it is very sensitive and even making the smallest mistakes it refuses to perform its functions.

What is needed when the computer needs renovation - incorrect work with files, operating system, viruses and Trojan horses, frequent system failures. In such situations the computer is in urgent need of formatting and if you do it, and, whether intentionally or unintentionally, everything disappears, the only way to return your data on the hard drive is by restoring.

To avoid this, you should know exactly what the formatting process is, where and when it has to be applied, what recommendations should be followed in order the data not to be removed and not to harm the system.

Format - this is a unique process that destroys the entire contents of your hard disk in order to obtain a blank disk ready for use.
There are two types of disk reorganization - of a physical and of a logical level.
The difference is that in reorganizing at a logical level the result is better, but on the other hand, when you need recovering lost data the process is much more difficult.
You should also be aware that the reorganization of the hard drive does not reduce its life.

It is said that at formatting the information cannot be restored, but in fact it is not so! In any formatting, to switching the disk to another file system (eg FAT in NFTS) the data can be restored.

Whether there will be successfully recovered data after formatting depends on how the files were located on your hard drive - not fragmented or were been divided into parts. The latter ones can be restored only partially.

It should be known and remembered that the fragmentation is one of the common causes of data loss.

Data recovery after formatting is a whole system of actions.

There comes a moment in which for a really quality reinstallation of the operating system is needed formatting. The reorganization of the hard drive is a guarantee for future upgrading of the computer and successful operation of the newly installed operating system.

It should be carefully checked if all data that are needed are retained.

It is recommended if it is possible to make backups on an independent media.

If for some reason you format the hard disk and at the end of the process you remember that it kept valuable files, there is no reason for concern. Recovering lost files is possible, but it is necessary to do the following.

You eagerly want to regain the lost in the process of reorganizing disk information? Under no circumstances you should try to do this alone.

It should not be recorded anything on the hard drive (HDD), and especially to continue the work with the computer - it must be shut down from the power button for not being able to saving any information.

Then as soon as possible you should call a specialist or take the computer to the specialized repair shop that deal with repairing disks and data recovery.
