Choosing between FireWire and USB (USB 2.0 & FireWire only) If your computer supports both interfaces, we advise you to use the FireWire interface. FireWire technology allows for daisy chaining of drives (i.e. you can connect the peripherals to each another) which avoids the use of a hub. Furthermore, sustained data transfer rates are usually higher with FireWire. 4.8. Data Transfers Data transfers are the flow of data that accomplishes a task, usually related to moving data from storage to computer RAM or between storage devices. During data transfers, it's best to wait before launching other applications on the same FireWire or USB port. Anomalies may arise with computers that have FireWire or USB 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 FireWire or USB cable is connected tightly and securely on both ends of the cable, from the drive to the computer. If you are using a FireWire or USB cable other than the one supplied with your LaCie drive, check that it is FireWire (IEEE 1394) certified. 2. Check that the power supply and ground connection are seated properly. 3. Disconnect your computer's FireWire or USB cable. Wait 30 seconds. Reconnect. Technical note: *Controller - This is a component or an electronic card (referred to in this case as a "controller card") that enables a computer to communicate with or manage certain peripherals. An external controller is an expansion card which fills one of the free slots (i.e. PCI or PCMCIA) inside your PC and which enables a peripheral (i.e. DVD/RW drive, Hard Drive, scanner or printer) to be connected to the computer. If your computer is not equipped with a FireWire controller card, you can purchase an external controller through LaCie. Contact your LaCie reseller or LaCie Technical Support (page 32, Contacting Customer Support) for more information.
