I have a 200MB ST9235AG, manual dated 1993 available and ORGASMIC, manufacturers should take note as opposed to what they're doing now, see for example real current consumption graphs at startup (as opposed to now giving some numbers that are just many times higher than the reality and would simply fit any disk they made over the last 2 decades and plan to make for next).
It sounds like a vacuum cleaner even if it's "just" 3449(!) RPM drive and 2.5" (albeit 20mm height!!!). Can't remember if it was doing like that back then or in the meantime the bearings dried up (or whatever is called what the entropy does to hard drive bearings). Still works 100% ok, and it sat from 2001 to 2019 without being powered on.
