The reason why the hard drive has bad tracks

1. Accidental power outage during reading and writing. Currently, the speed of the hard drive is mostly 7200 rpm. When reading and writing, the entire disk is in a high-speed rotating state. If the power is suddenly cut off, it will cause severe friction between the magnetic head and the disk, leading to bad tracks or even damage to the hard drive.

2. To prevent vibration, hard drives are very precise storage devices. When performing read and write operations, the floating height of the magnetic head on the surface of the disk is only a few micrometers; Even when not working, the magnetic head is in contact with the disc. When a hard disk is working, if there is significant vibration, it is easy to cause the magnetic head to collide with the data area, causing damage or scratches to the disk data area, and losing the file data stored in the hard disk.

3. Stay away from magnetic fields, as magnetic fields are a hidden killer of damaging hard drive data. Therefore, it is important to keep the hard drive as close as possible to strong magnetic fields such as speakers, mobile phones, radio stations, etc. to avoid damage to the data recorded in the hard drive due to magnetization. When the machine has a signal, it will generate a strong magnetic field, which may magnetize nearby hard drives.

4. Reduce frequent operations. If a program is running for a long time (such as large software or playing games), it is important to pay attention. This way, the magnetic head can frequently read and write to the same hard drive location (i.e. the sector where the program is located) for a long time, resulting in bad tracks on the hard drive.

5. Appropriate usage time: It is best not to let the hard drive work for more than 10 hours in a day, and not to work continuously for more than 8 hours. The computer should be turned off after a period of use to give the hard drive enough rest time.
