Right having spoken to Buffalo via email here is what has been said.
Please note the 3rd line saying that warranty has been voided by using TFTP tool.
Considering this is the Buffalo forums page im not overly happy to say the least. I feel that a warning note should be added to the TFTP tool how to page so others dont end up voiding there warranty.
I will be trying what Buffalo Tech Helpdesk have listed and will post back my outcome shortly.

Thank you for your reply regarding your Linkstation.
Unfortunately the warranty for your unit has been voided by using the TFTP tool
Please get the latest firmware from our website:
http://www.buffalo-technology.com/support/downloads
Extract the downloaded folder to your desktop.
Disable any kind of Firewall and Antivirus software.
Setup a cable network connection with PC and Buffalo-NAS to your router, with a DHCP Server, DHCP is required for to update for newer units.
Disable all other network connections on your PC (such as wireless connection).
Check that the PC and the unit are in the same IP-Address range.
Within the extracted firmware folder open up *updater.ini in Wordpad or Notepad.
Modify it as follows:
[Flags]
VersionCheck = 0 (modify this line from 1 to 0)
[SpecialFlags] (add this line)
Debug = 1 (add this line)
Save the modifications and start the *updater.exe file. Right click the title of the Updater window and select "Debug (D)".
This will bring up the Debug options. Select the following ones:
"Do not check version" : Install the firmware without checking if it's an older/newer version that the one actually installed
"Force Update" : This will have the program force the update even if it detects the same version was already installed.
"Erase User Config" : Takes your unit configuration back to default
Click on OK and finally on Update to run the firmware installation.
After that please try to set up RAID 1.
If you require any further support please let us know.
Regards,
Julia
