I bought a pc around December last year and my 1tb hdd is almost out of space. When looking at the drive cage where the hard drive is installed it looks like it wont fit any more hdds. How can I install a new drive? Im going to buy a large 4-6 tb hdd. Since my ssd has windows on it but the 1tb d drive appears to have a partition on it of some sort should I just swap the drives out?
