I have a question about the partitioning of 1TB Barracuda. From previous write up it said to partition it to 300gb and this one says to do 250gb. So when I format it do I fill in 300gb or 250gb? I know when I partition it 300gb, it doesn't really give me 300gb but actually it reads less. Is this where 250gb comes from? I don't know if it is just me doing something wrong or that is normal. I partition it through computer-manage-disk management-format. Thanks gang!
