I need to reformat and it has an red X

a red x on an iPod normally means you hard drive has failed, try formatting it in windows and then doing a restore in iTunes. if this doesn't work you could always try the old fashioned method that works for quite a few people. I'm serious here too, take your iPod charger dock down and bash it against a table or other hard surface. there is method to this madness, sometimes the hard drive read heads can become dislodged or stuck and this can free them. if all else fails take it apart and check if the hard drive data cable is connected properly, last resort means a new hard drive I'm afraid.
