Can't get my iPod to go to disk mode

I just replace the battery in my ipod. When i turn it on, it says that i need Itunes to restore it but when i hook it up, i get the red x. I heard that i need to put in disk mode first to restore it but when i try, all i get is the apple screen then a blank then a apple again, then it ask for Itunes again. Is there something i'm missing (besides my hold switch which i am waiting to come in) to get into disk mode?
