I just got my new TV but the external HDD connection is not recognised on my KDL43WG663BU TV. The message is "The HDD connected to the USB port was not recognised. Please confirm the connection." I have checked with the HDD requirements and it conforms, it is NTFS formatted HDD with over 256GB storage space, and have tried connecting it to both USB slots, unplugged the TV as it says on the Sony site, but still get the same message.
