Change Hard Drive as a Default Local Drive

Hello,
I am explaining my problem:
I have a 120 GB SSD and a 1 TB hard drive. When you install Windows 7 on my PC, I chose the SSD, so that my system runs faster. My problem is that, it has become the local disk, which contains all the images, documents, videos from default.
I want convert 1 TB hard drive as my local drive. If you know how, I would appreciate your taking time to help me solve this little problem. Thanks.
