Windows 7: How to delete folder in pictures library.

I just installed Win 7 pro and have it set like I want it. I have 3 hard drives. Two internal and one external. after install I wiped out second internal and external drives clean. Then I tried to do a back up and it failed and in my pictures library it says I have a folder from my external drive that does not exist so I need to delete that folder and the path I guess to make this work.Everything I have tried has not worked.

Thanks Ivan
