Wow, this question takes me back to like the 00’s when laptops had battery life measured in minutes.
umount maybe
Correct answer.
After setting the spin down timer using hdparm, unmount the drive and it will spin down accordingly.
This also makes sure you are not spinning down drives just for a few minutes of rest.Now just if my SSD were not heating itself to 40℃ when at its lowest power mode when unmounted…

Don’t do that
Why?
Creates a bunch of extra wear on the drives. They’ll die very fast. Keep them spinning.
This is what I would think instinctively too, but still asked as I did not know if my instincts are correct. It’s like starting and stopping the car engine on every traffic light…
Nah engines are fine since they don’t have enough time to cool down at a stop light. The oil mostly stays put over that short amount of time.
Seriously, I don’t know if this is precisely accurate but definitely don’t spin down. Data errors, software problems if it has to wait for spin up and then something experiences a timeout.
I’ve had some drives spinning for like twenty years without any problems.
My external HDD automatically does this regardless of OS, it is an Orico. I have 2 of them with a 2tb HDD in one and a 8tb in another. These are only used for playback and I believe the spin down after 30 sec of no activity
