hi guys ,ive got a question for you ,my friend at work has had his computer reformatted and has had windows xp put on, now the guy who has done it for him is a i.t guy, and my friend has tryed to explain that hes partitioned the hard drive in to 2 and put windows back on ,the i.t guy told him that the computer would run twice as quick as it did before because hes partitioned it ,the i.t guy -hes says its like having twice the power ,does anybody understand this ? and if you do could you explain this as i would like to know ! and if this is right how do you do it ? and will it work with vista the same?
