Abstract: A control circuit is connected between a motherboard and a number of hard disks for controlling power and data transmission of the number of hard disks. Each hard disk corresponds to one power control unit and one data control unit. The power control unit controls power transmission to the corresponding hard disk. The data control unit controls data transmission of the corresponding hard disk. When one hard disk is selected as an operation object to enter a disable state, the data control unit cuts off data transmission of the selected hard disk before the power control unit cuts off power transmission of the operation object. When the hard disk is selected as an operation object to enter an enable state, the power control unit resets the power transmission to the operation object before the data control unit resets data transmission of the operation object.

Abstract: A method for loading a configuration file from a remote server to an electronic device includes obtaining a default configuration file from the remote server, and executing the default configuration file to boot the electronic device, identifying a corresponding MAC list in the remote server according to hardware configurations of the electronic device, and obtaining a specific MAC value corresponding to an unused status flag from the MAC list. The method further includes obtaining a default MAC value of a network card of the electronic device, replacing the default MAC value of the network card with the specific MAC value, obtaining a specific configuration file from the remote server according to the specific MAC value, and rebooting the electronic device according to the specific configuration file.

Abstract: A computing device and method determines a position of a disk when the disk works abnormally. The computer searches out problem disks by determining if each disk included in the just a bundle of disks (JBOD) works normally, and determining if the computer can obtain a serial number of each problem disk. The computer notifies a user of the order number of the problem disk and an order number of the JBOD, in response to a determination that the computer can obtain serial number of the problem disk. The computer obtains the order number of the problem disk by deleting the data of the disk that works normally from the disk table, and notifying the user of the order number of the disk and the order number of the JBOD, in response to a determination that the computer fails to obtain serial number of the problem disk.
