LaCie DVD Dual Drive
User’s Manual
5. Technical Information
The following technical information relates to your LaCie DVD Dual Drive and gives some practical advice:
5.1. Power Autoswitching
Your LaCie DVD Dual Drive comes with an autoswitching power supply. This means that if the drive is connected to a
USB/FireWire connector on your computer, when you turn off the computer, the LaCie drive will turn off automatically.
Likewise, when you turn on your computer, your LaCie drive will turn on automatically.
5.2. Power Save
The LaCie DVD Dual Drive manages power consumption. If the system’s power save feature supports it, the drive will spin
down during the power save mode. After the system comes of out of power save, the drive will take a few seconds to spin up
to full power before it can be accessed.
5.3. User Advice When Using USB 2.0 or FireWire
5.3.1. USB 2.0 Host Bus Adapters and Performance
To utilize the newly-enhanced USB 2.0 performances, your computer must be equipped with a USB 2.0 host bus adapter card
(sold separately, such as the LaCie USB 2.0 PCI Card, or integrated by your PC manufacturer) and the appropriate drivers.
These host bus adapter cards, which include one or more USB ports, are shipped with special USB 2.0 drivers that enable the
computer to control the card. These drivers must be installed in order for USB 2.0 devices connected to the port to work at
their correct speeds. For installation instructions, please refer to the documentation that comes with the host adapter card.
LaCie supplies only the appropriate USB 2.0 drivers for its peripherals and does not provide drivers for third-party host
adapter cards. To obtain the right drivers for your host adapter card, visit your card manufacturer’s Internet site.
5.3.2. Data Transfers
During data transfers, it’s best to wait before launching other applications on the same USB or FireWire port. Anomalies may
arise with computers that have USB or FireWire 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 or FireWire cable is connected tightly and securely on both ends of the cable, from the drive to the
computer. If you are using a USB or FireWire cable other than the one supplied with your LaCie drive, check that your USB or
FireWire cable is properly certified. The cable that is provided with your LaCie drive is USB or FireWire certified.
