Disappeared Libraries

Hey guys, I got a problem with my laptop. My old laptop crashed some weeks ago. It doesn't work anymore if I press the power button. So I took the hdd and connected it with desktop-pc to rescue the data. I had to get the rights for the user folder and windows got it automatically for me. But now the folders like my pictures or my music are empty. Have I make a mistake? Can I get my data back?
