I have added the following lines
/dev/hda {
spindown_time = 60
}
/dev/hdb {
spindown_time = 60
}
/dev/hdc {
spindown_time = 60
}
to the end of my /etc/hdparm.conf file and rebooted.
Unfortunately, no any effect of these lines observed. For example, /dev/hdb which I rarely use shows
$ sudo smartctl -i -n standby /dev/sdb

How to check/force power conserving works?
UDPATE
I have tried all things, including ones in so called "duplicate" question, but they didn't work.
I can put drive into standby mode manually with
hdparm -y /dev/sdb
and it will stay in this mode until used. But once it used, it will never go into standby itself.
Is it possible to look standby timer, i.e. timer, which is counting time after last activity? Without this timer, auto standby feature can't work. And if this timer exists, but unavailable, then atuo standby can't be debugged.
