yvette., try to reset it 1. Toggle the Hold switch on and off. (Slide it to Hold, then turn it off again.)
2. Press and hold the Menu and Center (Select) buttons simultaneously until the Apple logo appears, about 6 to 8 seconds. You may need to repeat this step.
Tip: If you are having difficulty resetting your iPod, set it on a flat surface. Make sure the finger pressing the Select button is not touching any part of the click wheel. Also make sure that you are pressing the Menu button toward the outside of the click wheel, and not near the center. http://support.apple.com/kb/HT1320
If that does not work, is it still recognized under iTunes. you could try and restore it
Warning: Because restoring erases all the songs and files on iPod, back up any files you've saved on the iPod disk. All of your songs, videos, podcasts, audiobooks, and games can be loaded back to your iPod provided that you have them stored in your iTunes Library.
How to restore iPod
1. Verify that you have an active Internet connection, because you may need to download new versions of the iTunes and iPod Software.
2. Download and install the latest version of iTunes if necessary.
3. Open iTunes. Connect your iPod to your computer using the USB or FireWire cable that came with your iPod.
4. After a few moments, your iPod will appear in the Source panel in iTunes.
5. Select your iPod in the Source panel. You will see information about your iPod appear in the Summary tab of the main iTunes window.
6. Click Restore.
7. If you are using a Mac, you will be asked to enter an administrator’s name and password.
8. A progress bar will appear on the computer screen, indicating that stage one of the restore process has begun. When this stage is done, iTunes will present one of two messages with instructions specific to the iPod model you are restoring.
- Disconnect iPod and connect it to iPod Power Adapter (typically applies to older iPod models).
- Leave iPod connected to computer to complete restore (typically applies newer iPod models).
9. During stage two of the restore process, the iPod displays an Apple logo as well as a progress bar at the bottom of the display. It is critical that the iPod remain connected to the computer or iPod power adapter during this stage.
Note: The progress bar may be difficult to see, because the backlight on the iPod display may be off.
10. After stage two of the restore process is complete, the iTunes Setup Assistant window will appear. It will ask you to name your iPod and choose your syncing preferences, as it did when you connected your iPod for the first time.
