HDD only showing 32GB instead of 160GB

I’m not quite sure what’s going on here, but my hard drive is acting super weird. I have a 160GB drive, but during the Windows 7 installation, it’s only showing me 32GB of space. Does anyone know how I can get it to recognize the rest of the gigabytes?

A thought occurs to me..

Is the jump drive an HDD that's limiting

Or is there just a single 32GB partition set on the HDD while the rest remains unallocated?
