Hard drive stop spinning after a while

I have a Lenovo laptop, running Arch Linux + KDE. I noticed that when I am on battery, the hard drive stop spinning after a while, and it's very annoying to listen the disk starting again, and again. and again. I'm not interested in save energy with this, so how can I deactivate it?

I thought it was the laptop-mode, but I runned a systemctl status laptop-mode.service, and the service is inactive. Any idea of what could be triggering this?

man hdparm. Check out -B and -S flags. hdparm -B255 -S0 /dev/your_drive should disable any powersaving settings altogether.
You could use udev rule to run hdparm when you swithch to battery, but there are probably more elegant solutions as well.
KDE might handle this via its own power settings as well. I haven't really used KDE ever, so I'm not sure about this, but it's still possible.

What would be an elegant solution? This works pretty fine, but I don't want to be running hdparm with those parameters each time I run on battery...

You could (mis-)use laptop-mode-tools and configure it to do nothing else but disable hdd power management.
