Can the mechanical hard disk be repaired if it is broken?

The mechanical hard disk is broken and can be repaired. Generally speaking, mechanical hard disk damage can be divided into physical damage and internal data damage. For example, physical damage can be repaired by manufacturers or professionals. If some circuit damage is repaired by professionals, it can generally be used, but if the damage is too serious, it may not be repaired.

The data in the mechanical hard disk may be lost due to incorrect partition deletion, virus infection or formatting. In this case, the user can use the third-party data recovery software to recover the mechanical hard disk, provided that no new data is written into the mechanical hard disk.

Working principle of mechanical hard disk

All disks in the mechanical hard disk are installed on a rotating shaft, and each disk is parallel. There is a magnetic head on the storage surface of each disk, and the distance between the magnetic head and the disk is only 0. 1 micron ~ 0.5 micron, and the higher level reaches 0.005 micron ~ 0.0 1 micron. ..

All magnetic heads are connected to a head controller, which is responsible for the movement of each head. The reading and writing speed of mechanical hard disk depends on the rotation speed of the motor, because it needs to rely on the motor to drive the disk to rotate at high speed so that the magnetic head can find the designated position to read and write.
