when i connect my ipod to my PC, the light on the ipod turns on and my computer makes the noise signifying that something was connected, but then nothing...my pc doesn't show that anything is connected and neither does my ipod. it's not my pc because my sister's ipod connects and updates just fine. I tried troubleshooting it and then pushing the rewind/fastforward buttons for disk mode but that didn't do anything either. Since i can't connect I can't even restore it...
