...it is best to connect FireWire hard drives
directly to your computer and not to the 003 series
device. This will prevent hard drive errors
and data loss in case the 003 series device is powered
off.
Connecting 003 to a FireWire port of an external
drive that is connected to a computer
does not support maximum track count.
The second FireWire port on 003 or 003 Rack is
available for daisy-chaining FireWire devices
such as digital cameras or digital video recorders.
Even when it is powered off, 003 and
003 Rack supply power from the computer
through their FireWire ports, letting you recharge
batteries in other FireWire devices.
