I just made my switch from PC to Mac. I have an 80GB iPod, last year's model. I copied all my music files to the external drive and copied them to the music folder. I started Tunes, and Voila, same library as before. I plugged in my iPod asnd was asked if I wanted it syncrohnized to the Mac, and I said yes. So, everything seems ok. Why is my Mac still formatted for windows? Since everything works, does it really matter?
