You can try putting the ipod in Disk Mode.

*First reset the ipod (central and menu button at the same time)

*right after you reset the ipod you´ll see the ipod´s LCD black, in that moment change the buttons combination (central and play button)

After doing all of that you´ll see that the ipod displays DISK MODE. Connect the ipod to your computer and try restoring with itunes. If you use a Mac you can use the DISK UTILITY to erase the ipod´s drive and then restore with itunes.

Hope this helps!!!
