SyncGuardian is a freeware developped by CopyPod to protect your iPod music content (songs and music data such as playlists, ratings, playcount, etc. ) by preventing iTunes from unwanted synchronization / wipe thanks to its ability to easily set your iPod in manual or automatic update mode. With SyncGuardian, your iPod will never be accidentally wiped anymore. Unwanted synchronizations between iPod and iTunes library are the most common cause of music losses and song deletion.
