I'm using https://smarthdd.com/
to change the APM, since a time two of my HDDs doesn't save the setting anymore, but can't tell what I change because I don't notice it immediately. I wrote a few times with the developer of the tool, but we can't find a solution for the issue, it seems anything blocks access to restore/save the setting, so every restart the PC it returns to default.
I use Primo Cache alpha 4.0.0 with current Windows 10 2004 build 19041.338
The command "powercfg -attributes SUB_DISK 0b2d69d7-a2a1-449c-9680-f91c70521c60 -ATTRIB_HIDE" added a AHCI LPM - HIPM/DIPM
Unfortunately like every Microsoft document it is pretty shit, can someone tell me if active is right here? Because I have deactivate LPM in my BIOS, don't like it and don't care about the power.
There are Active, HIPM, DIPM, HIPM+DIPM and lowest
