I have started a defrag before, and it found a lot to defrag, however it started seeking out my music folders and specific songs. If I remember correctly it even rearranged or deleted some songs/albums. Is this normal? I've never defragged it since because of this. Also, I'm not sure what the best way is to go about clearing out the dust. Will this void the warranty if I take it apart to clean out its inside?
