How to recover data from hard disk?

One of the main think tanks of each computer can be considered a hard disk. Thanks to him, we can remember information and store it regardless of its nature. But, like any other mechanical device, the hard drive is subject to wear and risk of other negative influences: viruses, hackers, power surges, hardware failures, errors of the user, which inevitably leads to loss of information stored on the computer. And here before many users there can be a question: how to recover data from a hard disk? Further, several ways of how to do this will be considered, they can be applied in different situations, and also use them as add-ons to each other.

How to recover data from hard disk?

The easiest way to recover information is to access the backup files. However, this is possible only if they were previously created, as well as in the absence of significant failures in the drive. Once the loss of some data has been detected, you must turn off the computer from the network. In general, it is necessary to rely on a special automatic program in the matter of creating backup copies. If they were not created in advance, then despair is not worth it. When you delete data on sectors of the disk, information about the files is saved, and if they are not overwritten, the data can be restored by creating a complete copy of the disk and using the special utility Live CD. It is important to note that at the moment the most common method of data recovery is the use of various kinds of software, but this method is hardly the most effective. Utilities are not always able to recover data qualitatively and correctly. This is especially difficult for a user who has little experience with them. Sometimes with the help of such programs you can only harm the computer, after which it will be impossible to correct the situation.

If you are concerned about how to recover data from the hard disk in case they were lost due to a hardware failure, then only mechanical manual intervention is required. A similar procedure can be useful in case of damage to the surface of the disk. This part consists of a thin layer of crystals, some of which can crumble with time. The magnetic layer is sometimes damaged due to incorrect operation of the drive head. All these devices must be repaired to restore data, and to prevent their further loss. This is a difficult and painstaking work.

Data recovery is more complicated procedure in case of damage by spyware or malware. In such an attack, you must immediately create a backup, and also stop working with the computer. Data can then be restored by accessing the file table. Information on the hard drive may be at risk and due to errors in its boot sector. Sometimes, because of this, the computer does not even recognize the storage medium. But here there is an easy way to restore: you will need to boot the computer from a different media, after which access to information will be opened. You can even restore deleted photos.

Often the loss of information involves damage to the file system itself. In this case, you will determine the problem by the incomprehensible symbols that appear on the screen when you try to open the file. And here it is important not to write anything to disk. The data can be permanently lost due to any information entered.

When answering a question about how to recover data from a hard disk, it is worth noting that it is more correct to try to prevent any losses and related problems than to then look for a solution.
