my friend bought two i/o magic drives which are dw1655 & i have dw1620 at home & dru-810a (dw1640) at work.
strangely, her two 1655 drives’ tray opening & closing noises are quite different & to think about it, dru-810a noise is bit different.
one of her 1655 sound definitly smoother than the other 1655 & dru 810a is the roughest. 1620 sound better
anyone experienced such differences? should she return the noisy one to the store?
