Wd 3 TB my book essential hung on me last night, i waited for 3 hours to let it resolve it itself but i had no choice to turn it off. it was connected to a WD TV and i was watching a movie on it .So after i restartet the both my devices the WD TV was fine but the hard drive is no longer detectable on my MAC or the WD TV device's. i tried replacing the transfer cable but still no luck. it just keeps blinking. i wanted to reset the hard disk but there is no reset pinhole button anywhere.its really frustrating as my family home videos are on it which are priceless. I'm sure the software needs to close down properly and restarted again on the hard drive. please please someone help.
