My son wants an External hardrive, Can anyone recommend a good one say 250 MB to 500mb or is it GB whatever. I will be shoping at bestbuy,I like seagate but if I can get one that's dependable than another model will be fine. Next question , Do you plug the external hardrive into a usb port or Is it more complicated than that. Next question , how do you transfer data from an Internal hardrive to a External hardrive?.
