Given that the two common HDA faults (not counting head crashes) that
I've personally seen from drives of that era are stiction (ST225 and
ST241 especially) and the rubber head-knock-stop turning to goo (DEC
RD53/Micropolis 1335), my answer would be probably yes and probably
no. It depends, I think, on what faults the model in front of you is
known for if running periodically would help or not. I think the
rubber-to-goo thing is entirely based on the design of the drive and
the composition of the rubber itself and not power-on-hours; OTOH,
periodic operation might help stiction, depending design/construction
factors such as too much/too sticky medium lubricant.
Overall, I'd say run some vs not at all is probably better, but I have
a stack of 5.25" drives that haven't been run in years. I'm planning
on checking my idle drives for stiction as I find places to install
