My ipod classic 120gb black has scrambled file

your songs and pix should be backed up in your itunes library. So that should not be a problem. First try erasing and restoring you ipod in your itunes library. Sometimes it takes a few time to do. You can also hard reboot your ipod by powering it up and holding the center button and the menu button at the same time until the screen goes black for a second and then the apple logo will show up ... once you erase or reboot it connect it to you itunes and reload the media you want on it .. . hope this helps
