Yo guys, since where on the topic, kind of

, just wondering, Im going to reinstall Windows 7 64bit on my system. I have a 128GB SSD for the operating system and games only, and also I have a 1TB WD hard drive for storage. Just wanted to know do I need to format the 1TB HD even though im installing Windows 7 on the 128GB SSD, I know its a silly question but I wanted to know cause I dont want to get rid of all my stuff on that drive!
