I acquired a computer a while ago from somebody because they crashed it. I then re-installed windows 7 onto it and it works fine now. Although, I physically have 2 500GB HDD and can only access 1 of them from My Computer. I was wondering if there were a way to make this drive accessible as I am nearing critical mass on the 1 I have. I have checked all connections and all cords are plugged in. It just does not read the second HDD as ANYTHING. Could somebody please help me activate it?
