One of the main brain centers of each computer can be considered a hard drive. Thanks to him, we can memorize information and store it regardless of its nature. But, like any other mechanical device, the hard drive is subject to wear and the risk of other negative influences: viruses, hackers, power surges, hardware failures, user errors, which inevitably leads to the loss of information stored on the computer. And here before many users the question may arise: how to recover data from a hard drive? Next, we will consider several ways of how to do this, they can be used in different situations, and also use them as additions to each other.
How to recover data from a hard drive?
The simplest type of information recovery is accessing a backup copy of 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 worth relying on a special automatic program to create backups. If they were not created in advance, then you should not despair at all. When deleting data on the sectors of the disk, information about the files is stored, and if they were not overwritten, the data can be restored by creating a full copy of the disk and using the special utility Live CD. It is important to note that at the moment the most common way to recover data is to use all kinds of software, but this method can hardly be called 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 the question of how to recover data from a hard disk in case they were lost due to a malfunction in terms of hardware, then only mechanical manual intervention will be required. A similar procedure may be useful in case of damage to the surface of the disk. This part consists of a thin layer of crystals, some of which may crumble over time. The magnetic layer is sometimes damaged due to incorrect operation of the drive head. All these devices must be repaired to recover data, as well as to prevent their further loss. This is a difficult and painstaking job.
Data recovery is a more complicated procedure in case of damage by spyware or malware. With such an attack, you must immediately create a backup, as well as stop working with the computer. The data can be restored later by accessing the file table. Information on the hard drive may be in jeopardy due to errors in its boot sector. Sometimes, because of this, the computer does not even recognize the storage medium. But there is also a simple recovery method: you will need to boot the computer from another medium, after which access to information will be open. You can even recover deleted photos.
Often the loss of information is associated with damage to the file system itself. In this case, you will identify the problem by obscure characters that appear on the screen when you try to open the file. And here it is important not to write anything to disk. Data may be permanently lost due to any information entered.
When answering the question of how to recover data from a hard drive, it is worth noting that it is more correct to try to prevent any losses and related problems than to look for a solution later.
