How to solve the problem that the computer's mechanical hard disk cannot be read?

1. Click Start to open the control panel.

2. Click Device Manager to view it.

3. See if you can find the mechanical hard disk. If you can't see it, the mechanical disk is not mounted.

4, restart the computer, enter the bios settings (different brands have different access methods, you can search online) can you see the boot? Device priority, which is the choice of starting order of hard disk and other devices.

5. Go to the hard disk driver in the figure above and specify the order of the two hard disks. Just set the disk that needs to be started to the top. (generally press the page turning key to adjust)

6. Return to the next level at this time, enter the boot device priority, and the 1st boot device will be listed, which is the first boot device. Just select the hard disk.

Hard disk can be divided into mechanical hard disk (HDD) and solid state hard disk (SSD). Mechanical hard disk is a traditional common hard disk, which is mainly composed of disk, magnetic head, disk spindle, control motor, magnetic head controller, data converter, interface and cache.

The magnetic head can move along the radial direction of the disk, and the disk rotates at a high speed of several thousand revolutions per minute, so the magnetic head can be positioned at the designated position of the disk to read and write data. Information is written on the disk by the electromagnetic current of the magnetic head close to the magnetic surface, and information can be read in the opposite way. Hard disk is a precision device, and dust is its enemy, so the air entering the hard disk must be filtered.
