Disable hdd standby on boot

My laptop hdd started to go into standby without me doing anything. Based on noise it stands by after just a couple of seconds of inactivity. hdparm -S says bad or missing value. After setting it to 0 it all works fine until next reboot. How can I make it persistent?

I think what you are looking for is Advanced Power Management (APM) settings. This is controled with '-B <value>' where <value> is a number between 1 and 254. See the hdparm man page for more info.

I tried this as well disabling all power management but it is still reset on reboot

Oh, you should make a udev rule then. Otherwise, you can write a systemd service that will set it on boot. Just beware that there is a good chance that these setting will be lost after suspend.

Oh, this then kind of s...s. It's a laptop and I suspend it all the time. It all worked fine since ever but somehow changed recently, like a couple of weeks ago. I used to do "hdparm -S 0" but it is really annoying. I wonder what has happened

Not sure what happened in your case. But the suspend thing can be easily worked around. Just make a systemd service that both runs on boot as a oneshot, then also hook it into the suspend.target.
