Ok so i built a new computer last year after my old one was cooked by lighting. I got lots of great advice here and built a new computer wich i am enjoying greatly. I have run into an issue though. I bout a 1T HDD but i'm finding I want more room on my computer. Silly me dling to many game from steam i know right? Now I was ok building the computer but is it possible to add another HDD to my existing computer without having to reformat everything? I don't really want to lose all my existing info cause it's a lot of redownloading i'd have to do and my internet connection is not the most stable sometimes. I've got a legit copy of windows 7 and everything and if I have to I can reformat everything if there is no other option. My basic question though is can i just add another HDD to my computer without having to wipe the entire computer and start over? I just want more space for games and pictures, etc...
