Recovering data from hard disk pancakes
Restoring data from a damaged hard disk can be a difficult task, but in the case of pancake (switchable) hard disks, there are several ways to solve the problem.
The first thing to try is to connect this hard drive to a second computer or use it as a second/external HDD. If the device is detected and works without errors on a new computer, you can copy all data from it to another reliable drive.
If this method does not help or your HDD requires serious manipulations to correct data reading/writing errors, you can turn to information recovery professionals for help. There are a large number of companies and laboratories specializing in this type of service. They have already dealt with all possible types of broken hard drives and know about the intricacies of the work of each of these hardware elements.
Based only on a series of software-technically significant parameters of such systems, they differ from the classical idea of "iron" constructions:
1. The internal disk (screw) is a set of magnetic plates on which data is recorded.
2. The read/write head is a device for reading and writing data to the hard disk surface.
3. The spindle is the axis of rotation to which all the plates are welded.
In the event of a breakdown of one of these elements or the occurrence of other physical problems, specialized equipment and replacement of HDD components may be required.
However, the cost of professional help in restoring information is quite high, and the result is not always guaranteed 100%. At the same time, there is a risk of final data loss when carrying out any work with complex information storage systems without proper knowledge and experience in working with such equipment.
