I have my iTunes library on my 1TB external, and recently I have noticed that when I do stuff like changing the genre on songs that it takes a while to process. Anyone else having this problem? I have contacted WD and they said to try a new USB cable and then if that didn't work, to reformat it. So right now I am in the process of moving the 700gb to my imac so that i can try to reformat. Still I was wondering if anyone else encounters this when changing info in iTunes. Thanks!
