First off, I have a question for all the people with like 36GB of harddrive... how do you fill it all up? I find it impossible... I currently have a little over 200 songs in my collection. To be honest 10 GB is too much... now to my second question.. Is it possible to like downgrade harddrive? Lets say I have a 20GB Harddrive, can I sell that and buy like a 5 GB HD or something? What would the probable price be for a 20 GB HD and a 5 GB HD? Thanks!
