Interface and Data Transfer Information

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 In-

terface) standards. In any other conﬁgurations, we can-

not ensure 100% correct operation.

If you experience hanging problems, proceed as fol-

lows:

Make sure that the USB 2.0 cable is connected tight-

ly 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 certiﬁed. e cables provided

with your LaCie drive are USB 2.0 certiﬁed.

Check that the power supply and ground connection 2.

are seated properly.

Disconnect your computer’s USB 2.0 cable. Wait 30

seconds. Reconnect.

CAUTION: Do not connect USB cables so that

they form a ring of devices. ere is no need for

terminators on USB or devices, so the unused USB

connectors should be left empty.

TeChNICAl NOTe: Controller - A control-

ler 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 pe-

ripheral (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.

Contact your LaCie reseller or LaCie Technical

Support (section 6, Contacting Customer Support)
