I am thinking of swapping out my 160GB drive for a larger one. I would like to ghost the existing drive onto the new one. What is the best way to do this? I don't really want to have to setup the system up again from scratch. As the for hard disc itself, is there anything I should be aware of. Is it just a case of swapping new for old? I am thinking about using a 400Gig drive. Is it worth partitioning a drive of this size? Say a couple of partitions, OS, Documents, Music, Pictures? Or just keep it all on one? Thanks.
