A portable storage device with a hard disk drive is reliably started up using only the power received through the interface cable, e.g., a USB cable. By not providing power to the internal circuit in the interface cable, e.g., the USB circuit in the USB cable, while the hard disk drive is starting up, a maximum amount of current may be supplied to the hard disk drive. Once the hard disk drive has started up, the internal circuit of the interface cable may then be electrically coupled to the power supply through the portable storage device. The power supply to the internal circuit of the interface cable need not be interrupted after the hard disk drive has started up, even when idling.
