As soon as you switched them off, oil would produce the stiction effect. This is why the DFRS types cleaned their heads from time to time. They had a special track which would wipe off the oil from the trailing edge of the head assembly. And this is why many DFHS customers never encountered this effect, except if someone switched off a 7135 RAID over the weekend...
