Answer

Are both ends of the USB cables
firmly attached?
Check both ends of the USB cables and make sure that they are
fully seated in their respective ports. Try disconnecting the cables,
waiting 10 seconds, and then reconnecting them. If the drive is still
not recognized, restart your computer and try again.

and off when you turn
your computer on and
off.
This is normal. Your drive has an autoswitching power feature, which means that if your drive is connected
to your computer, turning the computer on will automatically turn the drive on. Likewise, turning the com-
puter off will automatically turn the drive off. If you wish to power off the drive while it is connected to your
computer, first make sure that your computer is not accessing the drive and then follow the steps on page

Is the drive connected to a USB
port on your computer, or to a USB

Hi-Speed USB 2.0 device can only operate at Hi-Speed USB 2.0
performance levels when it is connected directly to a Hi-Speed
USB 2.0 port or hub. Otherwise, the Hi-Speed USB 2.0 device will
operate at the slower USB transfer rates. For more information,
