For the record we have two Discoveries, 1996 and 1999 and neither exhibit any "Gear Whine'. The only whine I ever hear is my wife wanting me to stop for something to eat...
The only time I had any whine in the engine room, it was a bad bearing on the alternator. You can take a long shank screwdriver, press the plastic handle next to your ear and touch the different rotating parts; AC, Alternator, steering pump, etc and hear pretty reliably which one is making the noise. For the bits that you can't safely reach, while keeping all your body parts safely clear, get a 3 or 4 foot piece of small diameter rubber hose. Fuel line is great and just hold one end at ear other endnear the component you are checking. You can isolate sounds pretty quick. We used the rubber hose method, to synochronize the three side draft carbs. on our MGB.
