Just bought my new Spinpoint F3 because I have seen a lot of positive reviews on it. It started fine with that signature WHOOOOPPP noise, then the slight humming like many people experience. But when I try to copy some files over from my old Seagate, unusual quiet clicking/ticking noise appeared. I am quite worried that I have bought a faulty unit. Is this actually normal for the F3 to do this or should I go back to Umart and exchange it for another one since it's really new?
