Hi guys, I would like to ask you this simple question. I just bought the WD My Book Studio Edition 500GB and I'm just wondering what your WD will behave after you shut down your computer? As for me, when I shut down my computer, it goes into standby mode. The LED light is flashing every 5 seconds. Is this normal? Why is it not powering off? Is it okay to power it on & leave it on standby mode all the time?
