Question
Answer
The drive is not run-
ning noticeably faster
when connected via
Hi-Speed USB 2.0.
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?
See section
1.2, Minimum System Requirements
.
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.
