Important Note: USB 2.0 Host Bus Adapters and Performance
At the time of publication
(June 2002), 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.
Data Transfers
During data transfers, it’s best to wait before launching other applications on the same USB or FireWire port. Anomalies may
arise with computers that have USB or FireWire controllers that do not conform to OHCI (Open Host Controller Interface)
standards. In any other configurations, we cannot ensure 100% correct operation. Due to this, you may encounter hanging
problems. If this happens, proceed as follows:
1) Make sure that the USB or FireWire cable is connected tightly and securely on both ends of the cable, from the drive to the
computer. If you are using a USB or FireWire cable other than the one supplied with your LaCie drive, check that your
USB or FireWire cable is properly certified. The cable that is provided with your LaCie drive is USB or FireWire certified.
2) Check that the power supply and ground are seated properly.
3) Disconnect your computer’s USB or FireWire cable. Wait 30 seconds and reconnect it.
4) Check the Windows 98 SE version installed on your computer. Supported versions of Windows 98 SE are 4.10.2222A
and above. To check the version number, you need to execute the program
