[solved] hdparm issue

I don't find good values to spin down my HDD. With -y it works as well as with ridiculous low values like -B 32. But even a "hdparm -B 64 -S 12 /dev/sda" keeps the drive spinning. The disadvantage of -B 32 is that the drive is not up for a minute (-S 12) but stops after a few seconds.

To summarize:
hdparm -y /dev/sda: HDD stops immediately
hdparm -B 32 -S 12 /dev/sda: HDD stops after ~5s (and remains off, i.e. there is no activity which prevents spin down)
hdparm -B 32 -S 60 /dev/sda: HDD stops after ~5s
hdparm -B 64 -S 12 /dev/sda: HDD stops never

What can I do to stop the drive making noise after 1 minute?

Sure, but the drive spins down and I get positive feedback from the operation. Haven't tried hd-idle though.

PS: Tested with hd-idle. After removing systemd and udev with only hd-idle left, the device still spins down after a few seconds irrespective of the "-i 60" plus "*enabled=true" that I configured in conf.d/hd-idle. "hdparm -B" tells me  APM_level = 64, that seems to be persistent.

Re: [solved] hdparm issue

What about increasing APM value by a bit (33, 34...)? Your drive might not even have implemented the timer setting as the standby timer ATA command (-S).

Re: [solved] hdparm issue

After some tweaking I got it working without setting -S.

systemd
ExecStart=/usr/bin/hdparm -q -B 127 -y /dev/sda

conf.d
HD_IDLE_OPTS="-i 180 -l /var/log/hd-idle.log"

udev
none

Thanks for all answers.
