The clinical symptom is that the hard disk has a metal hitting sound, which is the back-to-position sound of the head,One BuG. In fact, the bug is only an energy-saving function in hard disk power management. After the head is restored, it is used to stop the hard disk.

My hard drive is Hitachi. The official ftool provides a tool to write configurations to the hard disk CMOS, which is more thorough.
