Move library to new HDD

I just installed second HDD in my Lenovo T430. I tried to move old folder to my new HDD(D:\). I clicked "calibre library" and then "switch/create new lib". when I put new location "d:\" and select option "move current lib to new location", I got message "windowserror [error 5] access is denied", then I select option "create an empty lib in new location", I got message "the folder D:\ is not empty, select an empty folder".

What did I do wrong?
