A device and method for reducing power consumption in a data storage disk drive operate to sense whether a disk is loaded in the disk drive. The device and method further operate to couple a drive power terminal and a host power terminal when the disk is loaded in the disk drive, and decouple the drive power terminal and the host power terminal when the disk is not loaded in the disk drive. The device and method thereby operate to decouple power from the electronic host device to the disk drive when the disk drive is not actually in use, increasing power efficiency of the disk drive, and conserving the amount of power drawn from the host electronic device.
