Question
Answer
The drive is not run-
ning noticeably faster
when connected via
Hi-Speed USB 2.0.
Are you operating in Mac OS 9.x?
Apple does not support the Hi-Speed USB 2.0 standard under
Mac OS 9.x. You will be limited to the slower transfer rates of the
original USB standard.
Are you operating in Mac OS 10.x?
Apple has incorporated native Hi-Speed USB 2.0 ports into its
computers.
Mac OS 10.0 & 10.1 users, to achieve Hi-Speed USB 2.0 transfer
rates, you will need to add a Hi-Speed USB 2.0 PCI or PC card to
your computer and update to Mac OS 10.2 or later.
Is the drive connected to a USB 1.1
port on your computer, or to a USB
1.1 hub?
If your drive is connected to a USB 1.1 port or hub, this is normal.
A Hi-Speed USB 2.0 device can only operate at Hi-Speed USB
2.0 performance levels when it is connected directly to a Hi-Speed
USB 2.0 port or hub. Otherwise, the Hi-Speed USB 2.0 device will
operate at the slower USB 1.1 transfer rates.
Is the drive connected to a Hi-
Speed USB 2.0 port on your
computer?
Check to see that the Hi-Speed USB 2.0 drivers for both your host
bus adapter and device have been installed correctly. If in doubt,
uninstall the drivers and re-install them.
Does your computer or operating
system support Hi-Speed USB 2.0?

System fan is not
running
Not all models include a system fan. To determine if your drive has a system fan, please see the data sheet
for your product at www.lacie.com. If your drive has a fan, confirm the outlet is powered, verify power con-
nections, and try an alternate power cable. The fan on the LaCie hard drive does not run continuously; it is
activated at certain temperatures.
