The design features of the hard drive Data Recovery make it a very delicate element of every computer. Its basis is a block of magnetic heads and a package of magnetic plates, which are mounted on the axis.

The small distance between the disk and the head and the high rotation speed make the design of the hard disk extremely fragile. Manufacturers are constantly working to protect hard drives from physical damage from impact, falls, and shock. Despite this, most of us have encountered the problem of hard drive failure, and as a result, the need to restore data . You can restore data with the help of donors.

Quite common are cases when the hard disk head sticks on the platters or fails, the disk controller breaks or the spindle motor bearing wedges . In such a situation, data recovery from a hard drive is possible using donor disks.

The essence of this approach is to replace a faulty hard disk element with a donor one borrowed from another similar disk. Despite the long duration of the data recovery process with the help of a donor, in fact, this is the only chance to save important information from a damaged hard drive.

To do this, often the wizard must first completely disassemble the disk, make the necessary replacement of parts or components, reassemble the disk and start reading data. This complex procedure requires the utmost care and precision.

Data Recovery

Since the disk controller stores some of the information that is necessary for the operation of the hard drive, when replacing it, service information should be transferred to the donor controller. To do this, you can either solder the ROM with data, or programmatically flash a new controller. After all the work has been done to start the disk, you can start copying all the data that has been saved on it.

What you need to know when recovering data with the help of donors?

It must be remembered that if it is necessary to remove the spindle motor or BMG from the donor disk, its further use becomes impossible. Each data recovery specialist is stocked with a whole set of donors from different manufacturers. This is because it is very difficult to find the right donor disk. Even if the model, series, and manufacturer of the donor and the failed disk are the same, the physical disks may differ from each other. 

To quickly search for “twin disks”, markings are used that contain encrypted disk parameters, such as the number or order of BMG heads, number of platters, disk firmware, etc. They are often displayed in the hard drive model code, which is printed on the hard drive itself. It is also often necessary to pay attention to the country of manufacture, and sometimes to the date of issue of this hard drive.

Hard drive failures are a very serious problem. Finding donor drives can be a very difficult and time-consuming process, and even after that, it is not always possible to recover Linkedin data from a failed hard drive. Moreover, when repairing hard drives yourself, there is a high probability of irretrievably losing all information.
