Just got a new external hardrive and had a big clear out of music, and for some reason I've loaded up my sets and a shit load of files are missing? I think the problem was the .asd files Live creates for a song were in my trash???? who knows why and then when I cleared them it can't find them. Also I did a manage library check and it said something like 13000 files Live uses were missing. I'm confused how this has happened in the course of backing up my hardrive? Any thoughts. Worried Lives program files have gone missing in the process but can't figure out why. Please advise!!!

Cheers
