Saving data to hard disk
Data is not recorded sequentially, but on a block whose addressing is based on torque. This tree is a specific expression of the organization of data on the hard disk. But to create a tree on your hard disk, you must first create a partition, the nature of which will determine the type of file system in which data is stored.
A hard disk is a meaningless and unnecessary storage space if the recorded data cannot be located, read and written easily. You can imagine a hard drive as a platform that can get a house, a building or a football stadium. Disk operation will be performed in accordance with the plan, cutting system and localization. This is exactly what the file system does. The more intelligent and complex the file system, the more it provides the user with interesting features.
On the basis of the TZ, the manager makes an estimate of the performance of work and coordinates with you the time and cost.

Hard drive data tree
The file system provides information on how to populate data blocks with various files and folders. The file system provides a way to access data associated with blocks of data on the hard disk. The file system provides information about the blocks of data released during the use of the hard disk. The file system should have a minimum time to access data from files stored on disk.
- The file system defines a mechanism for creating and deleting data.
- The file system allows you to determine the location of the file only with its name.

Several file systems are organized hierarchically, resemble a tree, and each folder and file have one path. All paths are called a data tree. In some cases, the tree structure may be damaged. This leads to the result of recovery, called "free", where all data is on the same level or in a tree other than the original.
Different types of file systems
A file system is a way to store and organize information in files on a storage medium. In some cases, different operating systems may use different file systems that are incompatible with each other. When transporting files from one operating system to another, the storage medium must be efficient and understandable by both systems. exploitation. Here is a list of the most well-known file systems.

Hard drive malfunction
All hard disk crashes can be divided into two categories.
- Hardware failures.
- Software breakdown.
Hard disk software errors
This type of hard disk failure affects all problems with access to the user if there is no hardware failure on the disk, such as partition loss, disk formatting, data erasure, etc. data recovery on a logical hard drive can be performed by the user, computer scientists or a specialist in the recovery of computer data on the hard drive.
Data recovery from HDD Western Digital (WD) hard drives. We are official partners of Western Digital.
Lab site is the official recommended data recovery partner for Western Digital. Hard drives opened and restored from us do not lose the factory warranty. Instead of a failed warranty HDD Western Digital, you will receive a new similar drive. At the same time, ordering data recovery work from us, you save from 3,000 to 10,000 rubles, because You do not have to buy a new hard drive to write recovered data.
Diagnostics malfunctioning hard drive
Provided that the disk is not subjected to mechanical or electric shock, this phase can be performed using disk utility. From the point of view of the nature of the breaking itself, regardless of its origin, two families of failures can be called. Logical error or software failure: this failure only affects the organization of user data on the hard disk. This type of failure is handled by software only for data recovery. On a damaged external hard disk, where the name of the software failure or logical failure. Obviously, support should be physically healthy. . This hard drive recovery phase is the longest and most difficult.
One of the most common problems on modern hard drives. Usually a lot of unreadable sectors appear on the disk at once, after which the operating system stops loading from the HDD or after loading it works with a heavy slowdown, messages appear about the inability to write or read files, folders with user data or even logical disks (if there are several) disappear. The main consequence of this malfunction is damage to the file system on the disk or the appearance of many errors in it, which makes it impossible to continue using the computer with such a drive. When using professional equipment such as PC3000 DataExtractor, it is possible to subtract content even from bad sectors.
Since the hard disk recovery tool may differ depending on the hard disk failure, instead of the disk utility, specialized data recovery software will be used, as well as the hard disk recovery tool. Physical Depending on the hard disk failure and the diagnosis, the hard disk intervention may be software, hardware or both.
Analysis and processing of the firmware requires a great deal of experience and extreme delicacy, because some manipulations can make the disk unusable and unrecoverable. Please note that damage to some parts of the firmware may permanently damage the hard disk. Replacing the read head, electronic board, or some components of the electronic control board is necessary for the drive to respond to read, write, and control commands. An experienced professional car is very delicate, and the error is very subtle. Some errors can be fatal to the hard disk. . His intervention in the diagnosis in the White Room is free of charge before the commercial offer.
A common and quite complicated in the restoration of the malfunction of modern hard drives, requiring highly skilled wizard and additional costs for parts (donor drive). The main symptom of head failure is the presence of extraneous sounds (clicks, clips) when turning on the disc. In this case, HDD is not detected in the BIOS, a computer with such a drive is not loaded and there is no access to files and folders. The method of data recovery from such a drive usually consists in the need to search for a donor disk of the same model and volume and replace the magnetic head unit from a new disk to a faulty one, after which a sector-specific copy of the disk with information to the new drive is made. The reason for the failure of the magnetic heads unit is usually the physical impacts on the drive: shocks, drops, vibrations.
After turning on the hard disk, it cannot be used directly by the data recovery software. Depending on the quality of the clone, you can be in one of the following cases. To do this, refer to the partition configuration on the hard disk.
Transferring recovered data to sufficient hard drive
However, if read errors are in the user data area, some data may be corrupted. To successfully complete this step, consider the following.
- The amount of data received.
- The disk data should be free space for 2-3 more data.
- The desire of the client.
- The operating system on which the disk will run.
The most common causes of this malfunction are short-circuits on the controller board due to improper connection of the power connector or applying an overvoltage to the drive (using an incorrect external power supply or power supply failure). A drive with such a malfunction does not spin, and burned-out chips can usually be seen on the controller board. To recover data from such a drive, it is necessary to replace the electronics board from the exact same drive. Moreover, a prerequisite for modern drives is the preservation of the original firmware ROM, which stores a unique part of the drive management firmware for each drive. At electrical breakdown of the disk electronics board, the switch of the magnetic heads block also often fails.
Recovering data on another type of hard disk
Recovering damaged data from an external hard drive adds a level of complexity compared to an internal hard drive. A multimedia hard drive is treated as an external hard drive. This implies the presence of a motherboard or interface located between the hard disk and the computer that uses it.
In addition to internal hard drive failures, an external hard drive may suffer from its own failures. As examples, the following failures can be mentioned. These broken hard disk crashes have no effect on the operation of the internal hard disk located in the case. The following are examples of external hard drive failures.
This problem is a situation where, for any reason, the heads of the hard disk do not have time to park and fall directly on the magnetic platinum of the disk. At the same time, the disk stops spinning (since the magnetic heads hold the plates) and makes quiet, periodic buzzing sounds. In contact with the magnetic plates of the disk, the heads usually fail, and to recover data from such a drive, it is necessary to replace the BMG from the exact same disk. Attempts to detach the heads from the plates themselves usually lead to bending of the head mounts, which, when placed on the parking zone, begin to scratch the magnetic plates of the hard disk. Therefore, with all the apparent ease of the problem, it is better to entrust the elimination of this malfunction to professional masters with experience in disks with such a malfunction.
Here we are talking about hard disk trays that are broken, and not about the term “broken” to denote a faulty hard disk. Very often, these discs break very quickly, after several months of use, leaving the user at a loss. Then recovering a failed external hard drive becomes the primary goal for extracting data from the hard drive. Recovering data from a hard disk is similar to restoring an external hard disk, with the only difference that a hard disk cannot be recognized directly if it is connected to a computer.
