Ok I just bought a Western Digital MyBook Essential External Harddrive, I can't seem to find a decent answer anywhere, thought i would try you guys and see if you could help. My question is, would it hurt the hdd to stay on all the time? Apparently this thing has a sleep/ECO mode. Its going to be located in an area that isn't easy to get to to turn off and on. Its also going to be in a well ventilated area as well.
