Updating the Firmware on a TeraStation or Linkstation from a Windows PC


IMPORTANT: For NAS models that support iSCSI volumes, it is required to proper dismount/disconnect the mounted NAS iSCSI volumes from the host/hypervisor servers before performing a firmware update. The firmware update process will automatically reboot the NAS which might cause data lost if iSCSI volume has not been properly dismounted/disconnected from the host/hypervisor servers.

  1. Access Settings, the TeraStation's web user interface, by entering the current IP address of the unit into a web browser. If the current IP is unknown the unit can be located using NAS Navigator. If NAS Navigator is not installed, download and install the application by clicking here.
  2. Go to the Buffalo website downloads page and enter your model number.
  3. Scroll to the firmware section and select the firmware update utility for Windows.
  4. Once the download finishes, right-click the zip file and choose "Extract All" or use your preferred utility to un-zip the file.
  5. Once unzipped you should see the original file along with a folder by the same name.
  6. Go down through the folders until you locate the file "TSUpdater.exe". Double-click the file to run it.
    Note: For LinkStation units the filename will be "LSUpdater.exe". Otherwise the procedure is exactly the same. You may not see the .exe file extension depending on your computer settings. 
  7. Windows may give you a security warning. If so, click Run to continue with the firmware update.
  8. Select the unit to be updated from the drop-down menu and click Update.
    IMPORTANT: Properly dismount/disconnect any mounted NAS iSCSI volumes from the host/hypervisor servers before proceeding.
  9. Enter the admin password for the unit and click OK. Note that this screen shows the current and new versions of the firmware.
  10. The updater will go through several steps and then reboot the unit.
  11. Once the unit reboots the following message should appear.
  12. To verify the new firmware version, check NASNavigator again. The new version should be displayed in the lower right corner.
