Handle a Frozen Apple Logo

Normally, when you turn on your iPod, the Apple logo appears for a couple
of seconds before the iPod loads to the main menu. Occasionally, the iPod gets
stuck on this logo.
If this happens to you, put the iPod into Disk Mode through the diagnostic
menu. Then connect the iPod to your computer and update or restore the iPod.
Sometimes you can get away with just updating the iPod, so try that first, but
usually you have to restore the iPod, too. As before, make backups of your
music files, because the restore procedure will obliterate them.
