PC cards typically limit the amount of power available through the primary USB cable. Therefore, the auxiliary power cable, which is included in the option, will need to be used. The drive is connected to a non-powered port or the power cable has been inserted into a USB connector that cannot provide enough power to run the device. To prolong battery life, the USB connectors on a mobile computer usually limit the amount of bus-power they can provide to USB devices and the USB 2.0 hard disk drive must use an additional power source to work in a mobile computer. Attach the included auxiliary power cable to an existing USB 1.1 port making sure the power connection is plugged in before connecting the drive to the USB 2.0 port.
