Hi all I am in need of a backup device for my music and pictures. I was thinking about a WD http://www.newegg.com/Product/Product.aspx?Item=N82E16822136324 or I can use my old Seagate sata 320 16mb HDD with an External enclosure. Was wondering if there was any benefits of using one or the other, If I use my old HDD will I have to reformat it to use it with my vista OS ? The old HDD has window XP on it. I would like to pull some stuff off it if I can before I reformat it if I have to. Not really sure what to do. Any help welcomed Thanks Niklas
