How can I Format/Erase my iPod Mini?

*How can I format/delete everything on my iPod without erasing anything in iTunes*

Restore your iPod in iTunes. Restoring will erase the iPod's hard drive, reload the software and put it back to default settings (it doesn't affect anything you have in the iTunes library on your computer). Once the restore is complete follow the on screen instructions to name the iPod and automatically sync your songs and videos onto the fresh installation. Press Done and the iPod will appear in iTunes and start to sync. If you want to update manually or using selected playlists uncheck the box beside the sync automatically instruction and press Done, it will default to manual mode and you can choose whatever setting you like: Restoring iPod to factory settings with iTunes 7

You're welcome, I'm glad it's working for you. Take care.
