Hi, I have a 120GB SSD card which is the main hard drive, it has windows and the computer software on it.... But everything I download gets stored to the SSD (C. I also have a 2TB Hard Drive(D which I can't set as my main drive. I have tried to change the Drive letters but that doesn't seem to work. How could I set the 2TB Hard Drive as the main drive so everything downloads to it. I'm not really sure on what to do.
