Ok so ive got my macbook pro now. Ive installed traktor ok, copied my collection ok with all beatgrids and tags i set on my other laptop. This time as i have a larger hdd i have copied all my songs onto it so i dont have to use my wd external hdd. What i need to know now is how do i set traktor up now so that when i eject the wd hdd i can still read the songs off the mac hdd?? without losing all the tags ans beatgrids?
