Hi, I currently have a 2TB Seagate Barracuda with a 120GB Samsung 840 Evo installed in my PC. I am now getting to the point where my HDD is getting fairly full and I'm not the sort of person who really wants to leave games uninstalled. I also have a 500GB drive lying around but it is full of the portion I transferred to my new drive and I don't know how to format it. My first question is, is there an easy way to format this drive? My second question is, would it be better for me to get another 1 or 2 TB drive, or get a 3 or 4TB drive instead? Also, although I am assuming this is fine, can you mix drive manufacturers as long as you aren't planning on doing RAID of any sort? Thanks.
