On many SCSI HDDs you may find a jumper that prevents the discs from spinning up when power is connected. Instead they get the start unit command from the controller/HBA. It may be called like "delayed spinup" "staggered spinup".
This is true but only delays the spin for a few seconds, The controller has to wait for an extra moment for the drive to spin up so it can then initialize it.
It was so the PSU wasn't overloaded with multiple disks all drawing power at the exact same time, not as a power saving feature.

2.) Should I spin my disconnected vintage HDDs from time to time so they won't seize like old cars and mopeds ?
Basically should I store HDDs disconnected or keep them powered up to reach max. reliability ?
You should also read/write to every sector as HDD's can loose their magnetism over time if not used. Spinrite offers this in its "refresh" scan, or plenty of others if you google spinrite alternative.
This also means more wear and tear on the drive. I think in the end its 6 of 1 and 1/2 dozen of the other. Personally I don't do anything on stored drives. I like to run a defrag on systems from time to time which I figure is close enough to a "refresh"
