I have 777 songs on my IPOD NANO. However, I only have 566 songs in my ITUNES for Windows music library because I accidently deleted the songs from another IPOD and deleted the entire library in ITUNES. I restored the ITUNES library by transfering music from my documents in the C drive, the result of which is that I have only 566 songs in my ITUNES library.
If I plug in the IPOD NANO with 777 songs and sync it with my ITUNES which currently has 566 songs, will the extra 211 songs on my IPOD NANO get erased during the sync process?
