Sudden power failure will damage the hard disk It's the biggest Although hard disks now have power failure protection circuits However, it will still cause data loss and even damage to the main controller of the hard disk motherboard So try to avoid sudden power failure Or directly purchase UPS
The possibility of physical damage to these two hard disks caused by sudden power failure is very low, so there is basically no harm. The specific reasons are as follows: 1. Mechanical hard disk: Mechanical hard disk is most afraid of physical impact, because it uses extremely precise and small magnetic head to read and write data on a high-speed rotating disc.Normally, when the hard disk is working, because there is a layer of air film generated by high-speed rotation between the head and the disk, the head cannot contact the disk, just like flying close to the disk surface, there is no impact and wear.When the power is off, the head returns to the position where there is no track in the center of the disk to ensure the lowest relative linear speed between the disk and the disk. The disk slowly stops rotating and the head slowly stops on the disk. 2. Solid state disk: Solid state disk has no moving parts and is almost a pure semiconductor storage device.Unless abnormal voltage and long-term electronic dissipation are input, it is difficult to cause physical damage to it due to mechanical shock and power on/off. 3. Sudden power failure will cause the greatest damage to the power supply.For hard disks, fragments will be added, which generally will not cause damage to the hardware.
You remove the mechanical hard disk and use only SSD to see if there is this problem? One possibility is the quality of the solid state disk. Another possibility is that the power supply is insufficient.So remove the mechanical hard disk for test.
