4.8. Data Transfers
Data transfers are the flow of data that accomplishes a task, usu-
ally related to moving data from storage to computer RAM or be-
tween storage devices. During data transfers, it is best to wait before
launching other applications on the same USB port. Anomalies may
arise with USB controllers that do not conform to OHCI (Open Host
Controller Interface) standards. LaCie cannot ensure proper opera-
tion when using interface controllers that are not OHCI compliant.
If you encounter a problem with an unsupported peripheral connec-
tors, such as a time lag (“hanging”), 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. If you
are using a USB cable other than the one supplied with your
LaCie drive, check that it is Hi-Speed USB 2.0 certified.
2. Check that the power supply and ground connection are seated
properly.
3. Disconnect your computer’s USB cable. Wait 30 seconds. Re-
connect.
TECHNICAL NOTE: *Controller - This is a component or an elec-
tronic card (referred to in this case as a “controller card”) that en-
ables a computer to communicate with or manage certain peripher-
als. 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 USB controller card, you can purchase an external controller
through LaCie. Contact your LaCie reseller or LaCie Technical Sup-
port (section
6. Contacting Customer Support ) for more information.
