created a new hdpar.con in /etc. I entered the following into this file:
command_line {
hdparm -S 120 /dev/disk/by-uuid/312cb74c-ee9e-4a50-adaa-677f2a61c50b
}
120 equals 10 minutes
it executes the command on the console, not in hdparm.conf
I enter the command via the console e.g.
sudo hdparm -S 20 /dev/disk/by-uuid/312cb74c-ee9e-4a50-adaa-677f2a61c50b
The value is adopted. Even after restarting the computer.
It's somehow strange and incomprehensible to me
