RESCUE STEPS
Step 1: Update the LaCie USB key
The included USB flash drive allows you to boot the LaCie 5big NAS Pro and run the NAS OS Rescue (LaCie key).
However, before running the Rescue, it is highly recommended that you download a more recent version of the
software as it may have been updated since you received your NAS.
NAS OS 4 and the USB Key: Make certain to update the LaCie key to the most recent version to maintain
compatibility with NAS OS 4. You can experience problems when attempting a rescue on a NAS OS 4 device
with a NAS OS 3 key.
The software that you download onto the LaCie key NAS is not the NAS OS. Rather, it is a utility to run the NAS
OS Rescue so that you can install or repair the NAS OS.
To update the LaCie key:
1. Insert it into a USB port on a computer with a connection to the internet.
2. Go to LaCie 5big NAS Pro
3. Choose the LaCie NAS OS Installer for your computer, Mac or Windows. The installer downloads as soon as it
is selected.
4. Go to you download folder and open the installer.
5. Follow the onscreen directions to update the LaCie key.
6. Eject the key from your computer.
