The opening recovery data we are talking about is for the mechanical hard disk, and the opening operation should be carried out in the clean room. There is no saying that the solid state disk is open for recovery, it is a combination of multiple memory chips, and the data recovery needs to be read chip by chip through the device. Then through manual reorganization of the data, the underlying open data recovery is a special case of hard disk physical failure data recovery.

When any part of the magnetic assembly of the hard disk (such as magnetic head, preamplifier, voice coil, drive arm, etc.) is damaged, aged or offset, the hard disk can not be recognized properly. The phenomena are as follows: there is an obvious abnormal noise, the motor does not run or everything is normal but does not recognize the disk. For this kind of failure, it is necessary to disassemble the hard drive for data recovery.

Before opening, we need to understand the relationship between the head and the disk. We all know that the data is stored on the disk in the way of magnetic recording, and the reading and writing are done by the head.

However, the magnetic head is not read on the disk. Due to the high-speed rotation of the disk, the magnetic head is suspended on the disk, which makes the hard disk head almost wear-free in use, which makes the data storage very stable and the life of the hard disk greatly increased. But the magnetic head is also very fragile. Under the working condition of the hard disk, no matter how small the vibration is, the magnetic head may be seriously damaged. Because the disk works in a dust-free environment, we are dealing with the failure of the magnetic head, that is, when replacing the magnetic head, it must be done in a dust-free room. For the hard disk, the interior of the hard disk cavity is very sensitive to dust. Therefore, at the beginning of the work, it is necessary to ensure that the data recovery clean room is sufficiently clean.

Moreover, it is necessary to have solid basic skills and skilled skills in order to greatly improve the success rate. Opening the market is a skilled work, need to see more practice, so that the hand is stable, the success rate will be greatly improved!
