haha, yes,gumballguy, you've just caught onto the important detail here. Note the OP says something about "certain operating systems".
Back when this was news a couple of years ago, linux was the only problem because it liked to access drives for journaling or something every 5 seconds and the idle time was set to 3 seconds back then. I haven't seen anything in WD Greengate 2011 to make me think it's even as big of a problem now as it was then.
