I have an external Panasonic 106D and my wife uses it. Over the years, it stopped working although it is still recognized by the machine. Is there a way to upgrade the driver or firmware to get it working again? I looked at the Panasonic website where I only found an .exe file. Unfortunately, the drive is not recognized in windows 8, so I can't update the firmware on that platform. Any help or suggestion will be greatly appreciated.
