I have windows 7 with a 1tb. harddrive , My friend just got windows 7 with a 1tb. harddrive. He's tickled pink about all the space he has, Says he'll probabvly never run out.I emailed and told him that he probably wouldn't have to worry about defragging either. He emailed back and said he thought W-7 defrags automatically But I think the Hard drive space is just so big that you don't have to bother defraging. So which is it? You don't have to defrag, because the harddrive is so big , or because W-7 does it for you?
