Hard disks. It can be said that it is very afraid of shocks. Because the hard disk is spinning at a high speed of 7200r m or 5400r m when it is running, once there is any vibration, then a bad sector will be generated in the place where the disk and the head are in contact, and it will be scrapped directly.
At such a high speed of rotation, even a single piece of dust can cause a lot of damage, let alone vibration.
Hard disks are mechanical hard disk drives (HDDs) and solid state drives.
SSD). Mechanical hard disk is a traditional ordinary hard disk, which is mainly composed of: platter, head, platter hinge and control motor, head controller, data converter, interface, cache and other parts.
The head can move along the radius of the platter, and with the high-speed rotation of the platter at several thousand revolutions per minute, the head can be positioned at the designated position of the platter for data reading and writing operations. The information is written to the disk by the electromagnetic current through the magnetic head very close to the magnetic surface, and the electromagnetic current changes the polarity, and the information can be read in the opposite way. As a precision device, dust is the enemy of the hard disk, so the air entering the hard disk must be filtered.
All the platters in the mechanical hard disk are mounted on a rotating axis, each platter is parallel to each other, there is a magnetic head on the storage surface of each disc, the distance between the magnetic head and the platter is smaller than the diameter of a human hair, all the magnetic heads are connected to a magnetic head controller, and the magnetic head controller is responsible for the movement of each magnetic head.

Hard drives can be very resistant to vibrations.
Because the hard disk is spinning at a high speed of 7200r m or 5400r m when it is running, once there is any vibration, then a bad sector will be generated in the place where the disk and the head are in contact, and it will be scrapped directly.
At such a high speed of rotation, even a single piece of dust can cause a lot of damage, let alone vibration.

The hard disk can be very afraid of vibration, because the hard disk is in operation when the file is destroyed, 7200r m or 5400r m is rotated at high speed, once there is any vibration, then in the place where the disk and the head are in contact, there will be bad sectors, and serious direct stupid scrapping. Even a piece of dust can cause a lot of damage at that high speed, not to mention vibration, if you look at mine, you know if it will be damaged.
The distance between the head of the hard disk and the platter is only 1 micron slow backup, that is, only one thousandth of a millimeter, maintaining such a distance is to rely on thousands of revolutions of high-speed gas power suspension, as long as there is a slight vibration, it will destroy the balance, the head will directly scratch the disk surface, causing irreversible and irreparable physical bad sectors, data loss. If it must be flipped, it must be turned before booting, and the hard disk should not be moved after booting.

Hard drives are very sophisticated storage devices.
When the hard disk is read and written, the head floats only a few microns on the surface of the platter; Even when not working, the head is in contact with the platter. When the hard disk is working, once a large vibration occurs, it is easy to cause the head to collide with the data area, resulting in damage to the data area of the platter or scratching the disk, and losing the file data stored in the hard disk.
Therefore, do not move the computer or mobile hard disk when working or before the spindle motor is stopped after shutting down, so as to avoid the impact between the magnetic head and the platter and scratch the magnetic layer on the surface of the platter.
In addition, extra care should be taken during the installation and removal of the hard disk to prevent excessive shaking or violent collision with the chassis iron plate.

If it is shaken, the disk head, the disk surface of the hard disk will rub and touch, and it will be damaged.
First, after Japan's defeat, it was very miserable, in the process of Japan's evacuation, many expatriates and Japanese troops died of hunger, many children were homeless, taken in by the kind Chinese, and many people returned to not even have enough food. After the defeat of Japan, in the process of evacuation, many Japanese had no way to return to China through normal channels. >>>More

It's very chaotic, first of all, his interpersonal relationship in the entertainment industry is more chaotic, and the chairman must get by between people, so I don't think what I think in my heart is important at all, in this case, it will be more tiring, and there is a gap in the middle, but you need to have a boyfriend or girlfriend or not, and you need to have a certain amount of communication, which is also more chaotic.

In recent years, the pace of China's economic development has shocked the world. However, the ecological environment has also paid a huge price for this. In an exclusive interview with Pan Yue, deputy director of China's State Environmental Protection Administration, the German magazine Der Spiegel said that these issues will soon attract national attention and will create thousands of "environmental refugees". >>>More
