i accidently formatted my IPod nano 7th gen i disk management in Windows Fat32

Hey Bruhhasapod7thgen109,

Welcome to Apple Support Communities.

It appears the iPod is in recovery mode, which means it will need to be restored to factory settings using a computer. We provided the steps below.

1. If you're using a Mac with macOS Mojave or earlier or a PC, make sure that your computer has the latest version of iTunes.

2. If you have an iPod nano or iPod classic, put your iPod in Disk Mode.

3. On a Mac with macOS Catalina or later, open a Finder window. On a Mac with macOS Mojave or earlier or a PC, open iTunes. Then connect your iPod directly to your computer.

4. Find your iPod in the Finder or iTunes, then select Restore iPod.

Hope this helps. Take care.
