I use an external hard drive to DJ with Serato Pro. Yesterday I plugged my hard drive into my new computer, cause I installed Serato to see if everything works on that computer. When I plugged my hard drive back into my old computer and opened up Serato my crates were not in alphabetical order it went from A to Z to a random order and half of my songs are gone. Is there any way I can fix this and bring back my original format?.. please, please someone help me.
