So I just got a new powerbook and I threw my music from my old computer (an iMac) onto an external HD and then connected it to my powerbook. I copied all the music onto here and then opened iTunes and had it find my music. It appeared everything worked fine, but for some reason some of my music must not have transfered. The music folder on my HD is 25.22GB where as the folder I copied my music to on the powerbook is only 19.43GB. Where did all this extra music go? Is there some reason my some songs wouldn't have transfered? Also iTunes found most all the songs on here; it reports 19.41GB So is there an easy way to fix this or should I try transfering all my music all over again?
