Both of my Mybook World Editions Power up when the ac cord is connected: by that I mean if the drives are powered down overnight, the mains lead is removed from the ac connection on the rear of he casing, then in the morning when I re-insert the ac lead, both of the drives power up without me touching the power on button on the front.
So effectively I dont have an ON/OFF button, just an off!
Is this normal?
