[Prior Art] A storage device is usually used to store data, and the storage device can be a hard disk or other storage device. When the amount of data is greater than the capacity of the storage device, a plurality of storage devices can be simply connected to expand the capacity. [0003] During system startup, while the power is turned on, the hard disk is immediately started to operate under its motor drive. Each hard disk has its own starting current. For example, the starting current of a single hard disk is 2A. In the case of connecting only a single hard disk, the instantaneous peak current of the power supply device is the hard disk booting electric hard disk. After the operation stabilizes, the current consumed by the hard disk will drop to a low average. If the number of hard disks connected is small, the impact of the instantaneous peak current on the power supply device is not obvious. However, in the case of a long access capacity, more hard disks need to be attached. Peak currents have a significant impact on the power supply. Example ^ When the hard disk is connected, when it starts at the same time, the instantaneous peak power is up to 16A. 'The ordinary power supply device cannot withstand such a large instantaneous peak current, and it is easy to burn, so it needs to be replaced with a special power supply device, but the cost Will be added.

When the power supply device is turned on and the corresponding delay time elapses, the controller start signal turns out to "low" in sequence, the power control switch is turned on sequentially, the current is output to the hard disk, and the hard disk starts to start. So many hard drives on the backplane can be started in sequence. The circuit and method of the invention utilizes the cable to control the sequential starting of each hard disk, so as to avoid the excessive peak current being excessively caused by the simultaneous start of multiple hard disks, without replacing the special power supply device.
