I just put a 120gb IBM-Hitachi HD in my cube, and it makes this oscilating hum.. hhuummmmMMMMMMMMMmmmmmmm....hhuuuummmmmMMMMMMMMMMMMmmmmmm... hhuummmmMMMMMMMMMmmmmmmm....hhuuuummmmmMMMMMMMMMMMMmmmmmm... hhuummmmMMMMMMMMMmmmmmmm....hhuuuummmmmMMMMMMMMMMMMmmmmmm... hhuummmmMMMMMMMMMmmmmmmm....hhuuuummmmmMMMMMMMMMMMMmmmmmm... I'm reading that the seagate V's make a high pitched whine, but I'm hoping to get a good 30db or lower 120+gb HD that won't drive me nuts :) jesse .
