7.3.2. Data Transfers

Data transfers are the flow of data that accomplishes a task, usually related to moving data for 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 on both ends of the cable, from the drive to the
computer. If you are using a USB 2.0 cable other than the one supplied with your LaCie drive, check that it is USB 2.0
certified. The cable that is provided with your LaCie drive is USB 2.0 certified.
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.
2) Disconnect your computer’s USB 2.0 cable. Wait 30 seconds. Reconnect.
Tech 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 on of the free slots (for example, PCI or PCMCIA) inside your PC and which enables a peripheral
(such as a 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 (11. Contacting Customer Support) for more information.
