Purchased ipod from china,disk format

Several problems - the short answer is that it will not work for two reasons - the voltage system is different, and it had previously been connected to another computer - and that formatting trumps your own.

You can run the Apple Recovery Tool from Apple's website, but I doubt it will work. - follow the 5 R's always - download a manual while you're at it -lol
