To follow up, I am confused but the hard drive is working now. In the first picture, you can see the bottom side of the Falcon motherboard with a "black spot". The second pictures shows the via where the black spot corresponds to with a black substance on it. This via is on the VCC circuit for the IDE drive. While 5v was measured with no issues, I found that this black stuff was as hard as an enamel. The top side of the motherboard shows no black enamel on it but it almost looks like this substance dripped through the via. I needed sharp tweezers to scrape off this enamel from the motherboard. This black spot is still on the cardboard backing.
I don't know if it's related but after I did this, the hard drive worked fine. The substance was not conductive and even if it was, it would not contact any other circuitry. I have taken this motherboard out several times when I replaced the IDE connector but, to be honest, I never really noticed the black spot but all of this said, the hard drive is now working like a charm. It doesn't make sense that his little drip of black substance makes a difference but I did probe around with a volt meter and ohm meter. I don't have any other explanation.
I do want to thank those who replied and I am very glad to have the schematics. That really helped.
