On August 17, the General Office of the National Development and Reform Commission released a 2021 of the first half of the year on the achievement of the dual control targets for energy consumption in various regions. In the first half of the year, the energy intensity of nine provinces (regions) in the country rose instead of decreasing, and Jiangsu Province was one of them. 

    In order to achieve the dual target of energy consumption, especially the target of energy intensity reduction, since September, 2021 has taken vigorous measures to implement the dual control of energy consumption by limiting power and output. But under the power-limiting policy, the sudden power failure has become the normal state, then, the sudden power failure will have an impact on the voice coil motor hard disk? As we all know, hard disk is one of the main storage media of computer, it is usually divided into solid state hard disk and hybrid hard disk, but now the main form of hard disk is solid state hard disk, which is sealed in hard disk drive. When it comes to hard drives, one of the most common concerns for users is whether power cuts will cause damage to hard drives. In this regard, Xiao Bian expressed his personal opinion: when power cuts off, there is no damage to the hard drive’s hardware, because the hard disk body (magnetic surface, track, cylinder and sector, etc. 4 structures) , read and write magnetic head components (read and write magnetic head, drive arm, drive shaft three parts) , magnetic head drive mechanism (voice coil motor, magnetic head drive car and anti-vibration mechanism) , spindle components (bearings and motors) four major components, it can be seen that the hard disk head is driven by voice coil motor, which ensures the structure of the hard disk head will automatically and quickly return to the start-stop zone. 

    Power failure, the main impact on the hard disk software, because the hard disk is “Write”operation suddenly power failure, it will cause data loss, partition table disorder (damage) and other consequences, and even produce bad logic.
