I took an old 320GB WD Hard drive out of an old laptop and I want the information from it. I have a port on the top of my tower that I can plug it into. The harddrive powers up, and my computer reads it. The problem is that it won't let me do anything with it unless I format it, but there should still be my old stuff on it like picture and music that I want. Is there a way to retrieve or recover that info?
