It's really common that iTunes error comes. More recently, Apple users report new iTunes error comes and it may erase all the content of iPhone data with consequence when they are going to sync music. It looks horrible, especially Erase and Sync option appears. In actual, it doesn't erase your iPhone data at all, but barely remove the iTunes content from that iPhone. However, if you lose your precious data on iPhone actually, turn to iPhone Data Recovery to recover lost data right now. Next, I will show you how to fix iTunes sync problems.

2. Type ~/Music/iTunes and press Enter and click on Go in the next prompted window.

Alternative Way to Fix The iPhone Is Synced with Another iTunes Library Error:
Even though iTunes is produced by Apple officially, unlike reputational iPhone, iPad and Mac, iTunes is undertook a lots of complaints because of its instability, crashes, errors and less readability. Generally speaking, I won't suggest users to copy files via iTunes in case of unexpected situations. Here Tenorshare iCareFone is highly recommended – it allows users to sync music, notes, contacts, videos, ect between iDevice and Windows/Mac with one click.
1. Download and install the program on your computer. Connect your device to the computer via USB cable.
2. Run the program and click Files Manager from the interface. Then select menu you want to manage.
3. Here I take Contacts for example. You can import and export files from/to computer. At the same time, you are allowed to edit each item manually.
