I have this scary problem happening to me. My music keeps disappearing from my general media folder and it shows as an exclamation in iTunes. When I try to search for the file, it's gone from the media folder. I have a main OS SSD drive and a Scorpio Black in the optibay drive. All my iTunes media is on the Scorpio drive. I hope I copied it properly. Organize my media is checked? This has been happening, I thought I was suffering hd corruption/data loss, but it was only MP3 files. When I try to search for the files, sometimes they have been moved to an iTunes subfolder but the files are missing and corrupted. (for example there will be duplicates of track 1-4 and 10-14, and then 5-10 just will be gone) This is insane. Does anybody know why this is happening? I can't find a solution or cause anywhere.
