I want to add files too it from my computer but when I connect them it wont pop anything up showing where I can access its folders.. It said something about there being an error or something.. Am I missing drivers? Ive tried going to My Computer to just open it manually but it only shows a Removable disk F and G. When I click on them it says I need to put in a disk? But it didnt come with one.. Im hoping this is just a simple misunderstanding between my two devices, any help would be super great! Thanks!
