ABSTRACT:
In a desktop computer, a hard disk drive activity indicator such as an LED is mounted on the front panel, remote from its associated hard disk drive which is mounted in the back of the housing. The LED is triggered in response both I/O writes for addresses reserved for use with the hard disk, and interrupt requests generated by the hard disk drive. Triggering logic on the motherboard of the computer detects these conditions, and a retriggerable monostable multivibrator which activates the LED. The LED is coupled to the triggering logic with by a conductor that need not be added as an additional part or assembly but instead is within an already-existing assembly such as the power supply.
