A friend of mine using a Windows PC as well as a 5G iPod. Her laptop recently crashed so she had to reformat and start over from factory defaults. As well, she had many songs on her iPod but doesn't have a backup of any of these. If she hooks it up to her PC again once she installs iTunes will it wipe out everything on her iPod? She claims she had this happen to a friend once but I know there has to be some way around this.
