Hello
Thank,
However, I am not sure to peak every things.
What does it mean HW-wise SW-wise? Sorry for my ignorance.
By the way.
I would like to make the hard drive sleeping.
I can use
hdparm -y /dev/sdx
or
hdparm -B 50 -S 36 /dev/sdx
but I would it stays sleeping till next reboot, or that I manually
wake it up.
I mainly use a ssd (and not the hard drive).
