5. Technical Information
5.1 Power Autoswitching
Your LaCie PocketCD-RW Drive comes with an autoswitching power supply. This means that if the drive is connected to a USB
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 CD-RW 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
The following technical information relates to your LaCie PocketCD-RW Drive and gives some practical advice:
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 port. Anomalies may arise with
computers that have USB controllers that do not conform to OHCI (Open Host Controller Interface) standards. Your product
has been tested and checked on computers with Intel USB platforms. In any other configurations, we cannot ensure 100% cor-
rect operation. Due to this, you may encounter hanging problems. If this happens, 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 your USB cable is properly certified.
The cable that is provided with your LaCie drive is USB certified.
2) Check that the power supply and ground are seated properly.
