Usage Notes
Usage with other USB devices
Because the drive is a high-powered
device (bus-powered; draws 500 mA of
current or less), it may malfunction if the
power from the computer is not stable.
Therefore, the drive operation is not
guaranteed in the following situations.
• When using the drive at the same time
as other high-powered USB devices
such as hard disks, CD-ROM drives,
scanners, and printers.
• When multiple drives are connected at
the same time.
• When using the drive at the same time
as a bus-powered hub.
Connection to the USB hub
• Connect the drive directly to your
computer’s USB port (root hub).
Operation is not guaranteed when you
connect the drive to other bus-powered
hubs such as keyboard hubs.
