Ubuntu 20.04 spin down HDD

Is there a way when the system is idle to automatically spin down the hard drives?

As it is now they seem to run forever.



perhaps this may help:

Many greetings.

I tried ‘hdparm -y /dev/sdb’ but no kuck.

Said command completed but no spin down.

Might be a factor device is a raid-1 drive with two ST1000LM049 drives.
