LaCie Data Bank Hi-Speed USB 2.0
User’s Manual
The Problem
The drive is working
slowly.
The drive is not running
noticeably faster when
connected via Hi-Speed
USB 2.0.
Questions to Ask
Are there other USB devices
connected to the same port or
hub?
Is the drive connected to a USB
1.1 port on your computer, or to
a USB 1.1 hub?
Is the drive connected to a Hi-
Speed USB 2.0 port on your
computer?
Does your computer or
operating system support Hi-
Speed USB 2.0?
Are you using a certified Hi-
Speed USB 2.0 cable to connect
your drive?
Possible Solutions
Disconnect any other USB devices and see if the drive’s
performance increases.
If your drive is connected to a USB 1.1 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 1.1
transfer rates. For more information, please see sections 5.3.
Optimizing Data Transfers and 6. USB Questions And
Answers.
Check to see that the Hi-Speed USB 2.0 drivers for both
your host bus adapter and device have been installed
correctly. If in doubt, un-install the drivers and re-install
them.
See sections 2.1. Minimum System Requir
ements – 2.1.1.

Ensure that the cable you are using has been properly
certified. The Hi-Speed USB 2.0 cable that was shipped with
your LaCie drive has been properly certified and tested to
comply with USB standards.
