Festlegen des Zeitlimits für das Herunterfahren auf WD Green-HDDs

Meine interne WD20EARS- Festplatte wird nicht automatisch heruntergefahren. Ich habe es versucht hdparm -S 1(5 Sekunden), aber nichts passiert. Ich habe das IntelliPower-Headparking mit wdidle3 von der Ultimate Boot-CD deaktiviert . hdparm -ydreht die Scheibe herunter.

Das Setup ist Archlinux auf einer i5-4590-CPU mit einem MSI B85I- Motherboard (UEFI). Die Festplatte ist nicht die Systemfestplatte. AHCI ist in UEFI eingestellt. Ich folgte journalctl -f | grep /dev/sdb, die Scheibe wird irgendwie nicht verwendet.

Gibt es Möglichkeiten, die automatische Spindown-Funktion zu aktivieren?
