First power up your terminal and log ind via. ssh. Ready for your first Debian command? To get new software installed you use: apt-get install package-name. We need a program to control the hard-disk. Its called sg3-utils.
type in: apt-get install sg3-utils
After the installation lets try to stop the harddisk from spinning around! Type in:
/usr/bin/sg_start --stop /dev/sdaAnd wollá .. congratz! :) your first spindown. Hopefully I'll soon provide a script which trigger this command if there is no harddisk activity after x amount of time. If you happen to know Of such, please send an e-mail or write an comment, thanks! :) You could use cron.. but if you are using the server it will spindown the harddisk no matter what = annoying
next we will be looking at rTorrent and the gui
