LaCie hard disk • DESIGN BY NEIL POULTON User Manual 4.4. Data Transfers A data transfer is 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 USB 2.0 port. Anomalies may arise with computers that have USB 2.0 controllers that do not conform to OHCI (Open Host Controller Interface) standards. In any other configurations, we cannot ensure 100% correct operation. If you experience hanging problems, proceed as follows: 1. Make sure that the USB cable is connected tightly and securely on both ends of the cable, from the drive to the computer. 2. Check that the power supply is properly connected. 3. Disconnect your computer's USB cable. Wait 30 seconds. Reconnect. Interface & Data Transfer Information page 20 TECHNICAL NOTE: Controller - A controller 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 (ex. CD-R/RW drive, scanner or printer) to be connected to the computer. If your computer is not equipped with a USB controller card, you can purchase an external controller through LaCie.
