4.1.3. 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 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. Due to this, you may encounter
hanging problems. If this happens, proceed as follows:
1) Make sure that the USB 2.0 cable is connected tightly and securely to the computer.
2) Disconnect the USB 2.0 cable. Wait 30 seconds. Reconnect.
Warning:
Do not connect USB 2.0 cables so that they form a ring of devices. There is no need for terminators on USB 2.0
devices, so the unused USB 2.0 connectors should be left empty.

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. CD-R/RW drive, Hard
Drive, scanner or printer) to be connected to the computer. If your computer is not equipped with a USB 2.0 controller card,
you can purchase an external controller through LaCie. Contact your LaCie reseller or LaCie Technical Support (6. Contacting
Customer Support) for more information.
