Hello, everyone. i have a dell dimension 4600i desktop. it has 2 sata I ports, and i was hoping to buy a large HDD for more capacity. My understanding is that sata III HDD's will work fine in the sata I ports, but please correct me if i am wrong. My other problem is, will the MB be able to recognize all the space on the HDD (I'm looking at 1 TB+)? If not, how can i find out how much space my MB can recognize?
