When you say " nano s ran windows format" what exactly do you mean by that? Honestly, im gonna argue with you anymore because you clearly demonstrated your inability do differentiate between what partition table, to which the hard drive on the nanos, or all ipods for that matter, can be formatted vs the operating system that device itself ran.
Also, the nanos can have windows formatting, or mac os formatting depending which computer it was plugged into.
And on that HUH question that i asked, i was clearly being sarcastic and was not challenging anyone but you're too dumb to tell the difference. That is all
