Are you sure that it has something to do with disk and not with processor? What if you run 'while true; do :; done', is not it sufficient to get rid of noise? If it is sufficient, then rebuild your kernel with HZ=100 instead of using default 1000Hz. At least it silenced my Compaq notebook. Best regards, Petr Vandrovec
