But the HDD I got is not showing ANYWHERE (2tb). It's not showing in BIOS or disk management. But, I've tried other HDD's I have access to. One is working and I'm using it right now, a 300gb HDD. The same thing happened to the other HDD's that I tried, couldn't see them anywhere. Just this one could be recognized. Has is it something to do with the Power Supply? Too low? 'cause I'm really stuck here. Thank you in advance!
