Most of the time all you would have to do when you first purchase a player is simply turn it on and go to "settings" then scroll on down and choose "memory info" and if it says 4000 mb "claiming to be 4gb" look at the bar underneath that and you'll see its already showing like 51% used already. Well duh! that should tell you right there. No need to even format or be a scientist to figure that out. You can not be at 51% used already and just bought it as they only come with 1 or 2 songs on them and maybe 1 video. If anything it should only show maybe 5% or 6% if that from them few songs and 1 video and then they count the firmware itself so. There you have it!. Just check before formatting or opening it up so you do not as they claim "void the warranty" if formatted or opened.
