The Problem
Error messages under Mac OS 10.x.
FireWire 800 will not work under
Windows 2000.
The drive is working slowly.
The USB 2.0 drive is not running notice-
ably faster than a USB 1.1 drive.
Questions to Ask
Are you having problems getting your
FireWire device to be recognized?
Have you installed Windows 2000
Service Pack 4?
Are other USB or FireWire devices con-
nected 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 USB 2.0 port
on your computer?
Does your Computer or Operating
System support USB 2.0?
Are you using a USB 2.0 certified cable?
Possible Solutions
If you are having problems with your
FireWire connection under Mac OS
10.2.x, upgrade to the latest version.
In order to operate FireWire 800
devices under Windows 2000, the
Service Pack 4 update must be installed.
This is a free download offered on
Microsoft’s Web site.
Disconnect any other USB or FireWire
devices and see if performance
improves.
If so, it is normal for the drive to run at
USB 1.1 speeds. A USB 2.0 device can
only run at USB 2.0 speeds when con-
nected to a USB 2.0 port or hub and
controlled by appropriate USB 2.0 driv-
ers.
Check to see that the USB 2.0 drivers
(drivers for your Host USB 2.0 port and
for your USB 2.0 device) have been cor-
rectly installed. If in doubt, uninstall the
drivers and reinstall them.
See section
5.2.1. USB 2.0 Host Bus
Adapters And Performance
for more
information.
Ensure that you are using a certified USB
2.0 cable. The USB 2.0 cable that was
shipped with your LaCie drive is certi-
fied.
