I am able to set both APM and spindown times using the command:
hdparm -S 246 -B 128 /dev/sda
Unfortunately I can only find the APM value in the information output:
hdparm -I /dev/sda | grep Advanced
How can I see the spindown time value? I suspect my disc it is ignoring my value. I would like to see it. Tried smartctl but with no luck, help.
Update: It turned out tuned is very aggressive. When I turned it down, my discs does not spin down. It was setting something there.
