I have a Mac Pro with a 4 drive RAID-0 (yeah I know, risky, but I keep a good backup). And since I upgraded to Snow Leopard, various files are: 1. Getting corrupted (movies go to 0KB or no longer play) 2. "Switching" with each other. I opened Donny Darko, and it played a DMX mp3 The other day I also played a Talib Kweli track, and heard some trance music I forgot I had. Wtf! Any ideas?
