WD My Book Studio LX firmware update failure

Hi

I’m sure i was using this one to update the firmware, when I was updating the firmware, it was all fine and I saw the processing bar is running, but suddenly it stops and failed, let me click the exit and try it again. Then I follow the instruction for the second time, it says "This version of the WD Firmware Updater dose not support the attached drive. Contact technical support for assistance. "

The digital label on the drive was also fade out and the light on the drive is off even it’s connected with the power and plug into the Mac. Any other solutions for this situation? THX!!!
