5.1. User Advice When Using FireWire
The following technical information relates to your LaCie Big Disk and gives some practical advice:
5.1.1 FireWire 800 Host Bus Adapters And Performance
At the time of publication (March 2003), only Mac OS 10.2.4 and higher, and Windows 2000 and Windows XP, support
FireWire 800 functionality, and the IEEE 1394b interface is not a standard feature implemented on the motherboards of all
PC-compatible computers.
To utilize the newly enhanced FireWire 800 performances, your computer must be equipped with a FireWire 800 host bus
adapter card, either sold by a third-party manufacturer, or integrated by your computer’s manufacturer. You must also be run-
ning Mac OS 10.2.4 and higher, or Windows 2000 or Windows XP.
5.2. User Advice When Using USB 2.0
The following technical information relates to your LaCie Big Disk and gives some practical advice:
5.2.1. USB 2.0 Host Bus Adapters And Performance
At the time of publication (March 2003), Mac OS does not support USB 2.0 functionality, and the USB 2.0 interface is not a
standard feature implemented on the motherboards of all PC-compatible computers. Future versions of Windows will include
USB 2.0 drivers to automatically manage USB 2.0 devices. For the most up-to-date information on USB 2.0 driver availability,
we advise you to check the Microsoft and Apple Web sites regularly.
To utilize the newly enhanced USB 2.0 performances, your computer must be equipped with a USB 2.0 host bus adapter card
(sold separately, or integrated by your PC manufacturer)and the appropriate drivers. These host bus adapter cards, which
include one or more USB ports, are shipped with special USB 2.0 drivers that enable the computer to control the card. These
drivers must be installed in order for USB 2.0 devices connected to the port to work at their correct speeds. For installation
instructions, please refer to the documentation that comes with the host adapter card.
LaCie supplies only the appropriate USB 2.0 drivers for its peripherals and does not provide drivers for third-party host
adapter cards. To obtain the right drivers for your host adapter card, visit your card manufacturer’s Internet site.
