I have an Asus EEE 1015PX netbook. It runs Linux (debian) without any powersavings enabled. E.g. no harddisk idle/spin-down tooling is running.
Now constantly the harddisk spins down after it has been idle for half a minute or so.
I can disable this with
hdparm -B 255 /dev/sda but this only works up to the next reboot. I tried using
hdparm -K 1 /dev/sda to make this setting permanent but this gives an input/output error.
This seems to be an issue with other EEE systems as well: my mother has an EEE Shell (a pink one) running windows 7 and that one has a down-spinning drive as well.
My question now is: how can I make it stop doing this? It makes the system very unresponsive and opening terminal/su to root/hdparm/exit shell every time I reboot the laptop (or had it suspend for a while by closing the lid) is annoying as hell.
