Whether to use the LED as a disk activity is a user preference.
Some like this usage while others find the LED too bright. So it
might be a good idea to make this choice a runtime parameter rather
than compile-time config.
The default is set to disabled as OS X does not use the LED as a
disk activity indicator.
