What does it mean ? Echoing 1 there should make the leds flashing on disk I/O ?
It's not like this, at least in my situation.
echoing 1 to the amber of each disk turn on the amber led, but not the green
echoing 1 to the green of each disk does not produce any effect. Perhaps I am
still missing some driver, but I wasn't able to find anything on the net

thanks,
