Just a shot in the dark here (I don't own an iPod), but do you have iTunes installed? If so, try this:
Switch the iPod to manual update and enable disk use
1. Open iTunes
2. Connect your iPod to your computer and wait for it to appear in iTunes.
3. Select your iPod in the Source pane under the Devices section to display your iPod preferences in the main library window.
4. Click the Summary tab in the main iTunes window.
5. Click the Manually manage music button. Changing from automatic updating to manual puts a check mark by Enable disk use.
6. Click OK in the message window.
7. Click Apply in the iPod preferences section of the iTunes window.
