Citations needed. Counterpoints for each: Heads don't suffer wear when parking. The armature does. If the platters are not spinning fast enough, or the air density is too low: the heads will crash into the sides of the platters. The main wear on platter bearings is vibration, it takes an extremely long time for the lube to "gum up." If its still a thing at all. I suspect it used to happen because they were petroleum distilate lubes. So, shorter chains would evaporate/sublimate leaving longer more viscous chains. Or straight polymerize. With fully synthetic PAO oils, and other options they won't do that anymore. What inrush? They're polyphase steppers. The only reason for inrush is that the engineers didn't think it'd affect lifetime. Counter: turn your drives off, thebsaved power of 8 drives being off half the day easily totals $80 a year- enough to replace all but the highest capacities.
