It is getting very demoralising!

I have just uploaded the images I have from Canada, and I have about 10 photographs of about the 2000 taken over the 2 weeks we spent there remaining. I truly have no idea where these images are going. I did have a phase where I uploaded them to Adobe Lightroom and they would disappear from my files on my Mac, why I have no idea, but to prevent loss of files I would create a copy on the same drive.

I have looked over the five HD’s I have attached to my Mac, my one drive account and in some other places but I am not able to locate ANY of the RAW files, all have gone? I can only think they too were on the Hard Drive that failed taking all with it.
