The drive is not run-

ning noticeably faster 

when connected via 

Hi-Speed USB 2.0.

Is the drive connected to a USB 

port on your computer, or to a USB 

hub?

If your drive is connected to a USB port or hub, this is normal. A 

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, 

please see page 35,
