Something odd happened with my iTunes library. A few random TV shows seem to have disappeared. They're still listed in my library but they have the little ! icon to show that the file can't be found, and when I try to locate it I can't find it anywhere. It's like it has been deleted from my hard drive. It seems very random (2 episodes of Doctor Who, 1 episode of Futurama, etc), and seems to only affect TV shows (all my music, apps, and movies are intact). I'm not too worried about recovering the files because I keep a regular backup of my entire hard drive, but I am a little concerned. I only delete TV shows from iTunes after I've copied them to another drive, and even then I only do that with entire shows so random episodes would not be missing. Also, this problem seems limited to iTunes as I have not noticed any other missing files on my system (though that doesn't necessarily mean there aren't any). Any ideas what could be causing this? The hard drive is fairly recent (3 months old) and checks out in disk utility so I'm leaning towards ruling that out. I'm running iTunes 10.2.2 under Mac OS X Snow Leopard 10.6.7 on a 2GHz Intel Core Duo MacBook Pro.
