I have an USB hard drive connected via USB and have no problem in general but when I pause a movie or anything I'm watching for just few minutes, HDD spins down.
Most users prefer that behavior. So in general it's not a bug, but a feature. ![]()
I tried to use hdparm in autostart.sh with this command: "hdparm -S 0 /dev/sda2" and also "/usr/bin/hdparm -S /dev/sda2" but with no luck: if I pause my watching, HDD spins down, always.
The thing that looks stange to me is the fact that if I lunch the command "hdparm -S 0 /dev/sda2" from an SSH shell when the HDD is sleeping then it start to spin up immediately.
The above facts result in the conclusion that your HDD firmware does the energy management, not LE.
- The HDD firmware spins down whenever idle in mounted mode.
- The HDD firmware takes hdparm as an abstract task, and spins up without further command interpretation.
