User’s Manual

5.5. Optimizing 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. With external drives, such as the LaCie d2 DL DVD±RW Drive, the data is transferred

from the drive to the computer via the FireWire or USB interface. The data is fed from the drive through the FireWire port

on the drive, and passes to the computer through the FireWire host-bus adapter interface.

FireWire

Computer manufacturer’s implementation of the FireWire host-bus adapter interfaces vary widely. For computers running

Windows 2000 and later, the FireWire interface, which is referred to as either IEEE 1394 or iLink on PCs*, is less

common as a native host-bus adapter. Nearly all recent Apple computers have native FireWire interface ports.

The FireWire interfaces specify certain requirements, filed under the OHCI (Open Host Controller Interface) standards. All

LaCie drives comply to OHCI standards and have been rigorously tested on computers that have host bus adapters that

also comply to OHCI standards. Unfortunately, not all manufacturers respect these guidelines, and anomalies may arise

with computers that have host bus adapters that do not conform to OHCI standards.

For the best performance, connect your LaCie d2 DL DVD±RW Drive directly to a native FireWire port on your computer,

and avoid daisy-chaining*. During data transfers, it’s best to wait before launching other applications that will be using

the same port.

If you do not have a native FireWire port, LaCie offers FireWire host bust adapter cards, also known as PCI or

PC/PCMCIA cards, that have been tested and comply with LaCie drives. Please contact your reseller or LaCie Customer
