LaCie Update Tool v2.0.1 adds the latest firmware support for LaCie drives with FireWire 400 and 800 and/or USB 2.0 interface. The LaCie Update Tool will not update Ethernet Disk or LaCie eSATA-only products. There are separate updaters for these Ethernet Disks, and nothing to update for eSATA-only disks. This update is compatible with OS X 10.3.9 thru 10.5.2, for both Intel and PPC based Macs.
The LaCie Update Tool will confirm if you have the most current firmware for your LaCie FireWire 400 and 800 drives. If the latest firmware is not already installed on your FireWire drive, you will be prompted to update the firmware. Some USB products do not contain changeable firmware and will not report a firmware version number.
