The energy saving option in GUI seems to not working, I’m monitoring power consumption with the watt-metter.
But we have a stable solution now with hd-idle instead.
You can build package from sources as descibed there, or you can use this deb: https://dl.dropboxusercontent.com/u/8635482/deb/hd-idle_1.04_armhf.deb
I tested this package with my wd elements external hdd, on the USB3.0, it works good.
I also tested it on my RaspberryPi, the same result.
Thanks for this useful post.
I installed the deb package by the command dpkg -i …/hd-idle_*.deb
and started it up after editing /etc/default/hd-idle file and by isueing the command /etc/init.d/hd-idle start
Result showed OK and I could see the process ID when listing processes.
However, it doesn’t seem to work, because my hdd doesn’t spin down after the specified minutes of inactivity. (Waited for longer time after turning off all access to the device to make sure no application is accessing files)
This is the content of my /etc/default/hd-idle file:
HD_IDLE_OPTS="-i 180 -l /var/log/hd-idle.log"
(No log file is being created)
Anything I am missing? Has anyone tried this in MyCloud?
