Hey guys... first post in this section of the forums. Hoping someone might have an idea of how to help me on this. The other night, I plugged my iPad2 into my MacPro to sync as I often do... when iTunes popped up a peculiar error message that said (something like) "Your iTunes Library file is not valid. It has been renamed iTunesLibrary.old and we've created a new library for you..." then taking me into a blank, completely empty iTunes library. I checked the Drobo where my library lives, and all the media files are still in place. I also maintain a backup on another physical drive in my system... so I have all of my media. After tons of forum reading, I can't find anything on how to "fix" the supposedly corrupt library file. So I resigned myself to having to copy all of my media back in. I did a giant batch copy from the old library into the new library's "Automatically Add to iTunes" folder and let it run overnight. When I fired up iTunes the next day it started "ingesting" all the content. At the end of the day, though, I wound up with 19,646 songs (or "items") which is shy of the 20,100 or so I know I have. And while that's "pretty good" where recoveries go, I can't help but wonder where the other 450'ish items have gone. Someone mentioned that online radio links wouldn't be there anymore, that might account for 15-20 of what I'm missing, but the rest is a mystery. I have no idea how to tell what is missing... any ideas?? Is there a different way I should handle this? Thanks in advance for any ideas and help!
