BR> I took a peek inside one of the Mobile Docking trays I
have (they ha
BR>activity lights) and they tap off of either Pin 1 OR the pin vertically
BR>adjacent to it (:) then thru a 100 ohm resistor then to an onboard IC then
BR>another resistor then the LED. Very small stuff or I'd develop a schematic.


I just took a look at a 2 1/2 to Laptop Drive to a Standard IDE cable
 adapter I have.

IT looks like the Activity light comes off pin 20.
The one on the same row but the opposite end of the IDE connector from
Pin 1

The circuit is a feed off the + wire of the drive power connector, going
through a resistor to the + lead of the LED with the - lead of the LED
going to pin 20 on the IDE connector.
