What I could find out was that with a cross over cable connected directly to my PC and an IP scanner I scanned the whole 169.254.255.255 subnet and found the device on 169.254.120.181. I could ping the device but the WD Discovery tool could not find it and I was unable to SSH or http(s) into the device.
I have created an Advanced RMA with WD. Once the new unit from WD gets here I hope to swap drives and still see my data, but I pretty much resigned to all data is gone at this point…
