            		On the other hand...

	It could be selected-drive led...  At least Toshiba MK134FA
	has one red led in front of drive showing wether the drive is
	selected active by controller. In case of one hard-drive, the
	only disk is always selected = led is on. 

	If you add more drives in same controller, "active led" should
	go on and off in drives when changing drives...

	So if you got " HD active indicator " led from controller and
	it seems to work properly, everything is OK. Don't worry. Be happy !

	PS. Some disk-caches cause "all drives selected" - phenomenon
	    Don't worry about that either.
