My computer is Sunlogix AT and I've two hard disk installed, too. Both of them contain a LED and there's another LED on the computer's front panel. It flashes every time when any hard disk is accessed. What comes to hard disks' LEDs, the led on the first disk shines nearly all the time, but when I access to the second hard disk, the the first HDs light goes off for a little time and the second HD's light goes on. But when that read/write access ends, the first HD's led goes on again and the second goes off. So when I stay on second hard disk (i.e. no disk accesses on any disk) first HD's led is on. -- Tapio Keih{nen | "Whenever you dream Mesihein{nkatu 2 B 6 | you're holding the key, 33340 Tampere, Finland | it opens the door public@cc.tut.fi | to let you be free" - RJD '85
