As one of the most common mobile storage devices in daily life, mobile hard disk has been well received by consumers. Compared with other mobile storage devices, mobile hard disks can store and transfer larger data and transfer faster. However, although the advantages of stimulating hard disks are many, they still have their limitations. If you use mobile hard disks, you should not pay attention to them. The maintenance of the hard disk and some precautions when using the mobile hard disk, then the mobile hard disk will be like the normal storage device, data loss will occur.
Therefore, mobile hard drives must choose quality products when purchasing. It is a good choice to purchase brand products through the formal electronic mall or the online shopping platform to ensure the direct supply of the factory. A lot safer. Of course, the maintenance of the mobile hard disk during use is also essential. Normally, there are four reasons for the damage of the mobile hard disk:
1. The mobile hard disk head assembly is damaged.
Mainly refers to the damage of a part of the magnetic head component in the damage repair of the mobile hard disk, causing some or all of the magnetic heads to be unable to read and write normally. There are many ways and possibilities for damage to the head assembly, including dirty heads, head wear, head cantilever deformation, magnetic coil damage, displacement, and the like.
2 , the mobile hard disk control circuit is damaged
It refers to the disconnection or short circuit of a part of the electronic circuit board damaged by the mobile hard disk, or the damage of some electrical components or IC chips, etc., resulting in damage to the mobile hard disk. After the power is turned on, the disk cannot be rotated normally, or after the rotation. The head cannot be searched correctly.
3, mobile hard drive comprehensive damage
Mainly refers to the problems caused by the damage repair of the mobile hard disk due to some minor changes. Some are mobile hard disk damage repairs due to heat or other relationship caused by the chip aging; some are mobile hard disk damage repair after the shock, the outer casing or disk surface or motor spindle produces a slight change or displacement
4 , mobile hard disk sector physical damage
Refers to physical damage to the disk surface due to collision, head friction or other reasons, such as scratches, magnetic loss, etc. Soft damage includes track servo information errors, system information area errors, and sector logic errors (generally referred to as logical bad sectors).
The above is the four reasons for the damage of the mobile hard disk. Because the hardware damage of the mobile hard disk will result in the loss of stored data, it is very important to maintain the mobile hard disk. If you just lose data due to misuse, you can retrieve it through some common data recovery software.
