Welcome to my “Physical hard drive recovery.”
Physical faults on hard drives - what is it and how do they occur?
In general, the reasons for the failure of hard disks can be divided into several types:
- One or more magnetic heads fail
-Imgator failure in the BMG
- Controller malfunction
-Disks of reading / writing the surface of the disk
-Physical damage to the surface of the disk (sawing)
Failure of one or more magnetic heads
With such a malfunction, a very long hard disk definition is typical, knocking when power is applied to the drive. The nature of the knocking is as follows: after the power is applied to the hard drive, the heads come out of the parking lot and try to catch the servo marks on the surface, but they can not do this and beat about the positioner. Knocks can last an infinite number of times. Often after 4-5 knocking the drive extinguishes the engine. In the event that this applies to WD hard disks - this could mean a malfunction of one head. The reasons for the failure of the BMG are several - the loss of the magnetic properties of the heads due to overheating or contamination. Also, similar symptoms can occur after physical influences (dropped, shook the disc during operation). To restore the information requires a working block of magnetic heads.
Data recovery in the case of faults of the BMG, in this case, occurs by permuting the block of magnetic heads from a working donor disk. Repair of the hard disk with such a malfunction is impossible.
The failure of the switch in the MBG
This breakdown most often happens due to the failure of the controller elements, less often by itself.
Disk repair is not possible. You can restore the data by transferring the BMG.
Controller malfunction
There are countless reasons and types of malfunctions. If you use a hard drive on a bad power supply, the stabilizers may fail 5 or 12 volts. The same situation can happen after the voltage jump.
Very often a controller enters the controller, because of which there is a short circuit on the board, which damages anything (a twist, a processor, etc.)
Restore the data, in this case, is possible, repair, most often, too.
Errors of disk surface read/write
Such errors appear both in cases of failure of the disk surface and as a result of the incorrect operation of the control elements and data transmission channels of the HDD (logical bad blocks).
In the process of repairing the hard disk, the foundation "bad" sectors are placed in the factory defect table.
Data recovery in such cases is possible, repair drives also.
Physical damage to the surface of the disk (cuts)
Alas, almost never fails to recover data when there are blanks on the surface of the disks. They instantly "eat" the heads.
Repair of the drive, in this case, is not even discussed. It is not possible

We manufacture data and information recovery from hard disks in Minsk. Data recovery is performed from HDD of any manufacturers, form factors and file systems.
Data recovery is performed for all types of malfunctions - logical, physical, controller malfunctions, magnetic head unit malfunctions, spindle wedge, "sticking" heads. Do not be discouraged even if you dropped the hard disk or accidentally got wet. We can restore the data in this case.
Everyone must do their job. Our business is data recovery. If you have a hard drive out of order and you care about the information that was on it - please contact us. Many years of experience allow us to carry out all the work to restore data at the highest level.
FAQ:
1. Why did this happen?
2. How do we recover data from hard drives?
3. What should I do if the data is lost?
4. How much does it cost?
5. How long does it take to recover data from the hard drive?
Why did this happen?
There are many factors. One of them is the human factor. The data may disappear after the system has been reinstalled, after partitioning, due to the lack of antivirus (or old anti-virus databases), the file system and information can spoil.
You can learn more about logical errors on the page - Logical errors on HDD. If you accidentally formatted a partition on which there were important data and you need to restore the files, in no case do not write anything to the disk. The recovery of data in the case of writing new information to disk is very difficult.
Did you drop your hard drive? Unfortunately, this is not the uncommon and very unpleasant situation. Most often this happens with external hard drives and laptops. In modern laptops, there are systems of protection of hard disks. However, if you drop your laptop, especially during operation, the chance of hard disk failure is very high. Also, the hard drive may fail after a voltage drop or short circuit. When installing/removing HDD, users often damage parts on the controller. After all the defects described above, you can restore the data (except for the blanks on the working surface.) Find out more about the physical malfunctions of hard disks and data recovery with such errors.
But the human factor is only one of the reasons. The failure of the hard drive can occur without any apparent cause. He can start to play strange sounds - creaking, grinding, tapping or simply stop spinning and giving out any signs of life. Data recovery in such cases is performed after a full diagnostics of the drive. The nature of squeaks, grindings and hard drive writings can be very different.

How do we recover data from hard drives?
First, the hard disk is diagnosed. Diagnosis is free. After the diagnostics specialist connects with the downloader, describes the problem and reports the amount. In the case of consent, the performer starts work. In case of refusal, the customer picks up the hard drive and does not pay anything. Only after a full diagnosis can you tell how this data will be restored from this hard disk.
If the hard disk is healthy, but there are logical errors (accidentally formatted partitions with information, deleted partitions, erased files, etc.), then to successfully restore the files on the hard disk, all possible file system structures are searched, then on the basis of them a tree is built (starting from the root directory to the destination files). If the file structures are completely erased, then the so-called draft data recovery is applied. It helps in the most difficult situations. Minus the raw data recovery is that with it, the file names are lost. For this reason, it is used in very critical situations.
For physical faults, a fault is diagnosed, during which the fault is localized. Conditionally, it is possible to divide faults into 2 types - controller malfunctions and magnetic head unit malfunction. To determine the method by which the data will be restored, it is necessary to find a malfunction and, based on this, to choose the safest and optimal way of data recovery. Many years of experience allow us to do this without errors. We never risk your data, pondering each step with your head.
In the event of a failure of the BMG (Magnetic Head Unit), the data recovery process is even more difficult. However, we are in a position to deal with all types of faults of MBG - sticking of heads, jamming of the spindle, complete failure of the heads, with the sleeping switch of the heads.

What if the data were missing?
To begin with, do not panic. It is best to immediately remove the disk and refer it to specialists for data recovery.
