I have nearly 2TB of Movies and TV Shows copied to iTunes on an external hard drive. Last night, I was unplugging a cord behind my desk and I accidentally unplugged my HD. Well, when I plugged it back in and tried to open iTunes, it said that it was corrupted.
I couldn't figure out a work around for this so I made a new iTunes Library and pointed it to my media. I still couldn't get it to recognize my movies etc. This morning I tried to manually open one of the movies with Quicktime player and it says that it is not a movie file. HELP!!! This was days and days of work to transfer my DVD collection over.
