i got an laptop with two drives (ssd & hdd). Since I don’t need the HDD atm and it’s making quite some noise and vibrations, I want to put it in sleep mode (and also save some battery).
Using hdparm i can do it manually, even using this ArchWIKI tip works fine and the drive spins off during boot.
The problem is, as soon as i login (KDE) the drive spins up again and won’t go back to sleep - ever. I can’t figure out why and all tips i’ve found didn’t work (udev rules).
it’s /dev/sda/ and not mounted nor partitioned
Thanks for any help
