For example, you can play witch num/caps/scrol lock leds on your keyboard easily, but there's no such standard for cheap generic drive enclosures. Fancier ones use saf-te, as others already mentioned. What you need to do is to figure out what your case and enclosures use to implement LEDs and if that is exposed to OS. Only then you can start asking how to control that from OS ... -- Jure Pečar http://jure.pecar.org http://f5j.eu
