So, a few months back I built my first PC from scratch after seeing a fair bit of PC building vids, the rig has been absolutely wonderful and beyond my expectation, as overkill as it may be with its 32 gigs of ram though, unfortunately with the new build I installed a new seagate 2 TB HDD in addition to my old 1 TB ( toshiba I believe, don't know for sure),I set it up with my other HDD in the drive cage that came with my case, plugged it in with the SATA cord the other needs too, both are plugged in with SATA cords and both are plugged into my motherboards SATA cord input,boot up the computer like normal,but it does not show up with the other one, as far as I can tell I don't think it shows up in BIOS either but through all my tinkering and researching, I cant find anything on how to get it to work alongside my new one, I remember seeing something about slave and master drives, and I believe that's what I need to setup unfortunately I don't know how. So what would I need? My friend says i just need little connector clips for the back of each drive and put in the appropriate position, but where would I find these clips? Or how would I set up both drives to work alongside each other?
