Running on Windows 7, latest version of iTunes. I transferred all 20gb of my music to an external hard drive the other day. I changed my iTunes Media folder to a folder on my external and had iTunes consolidate all of my files to the new folder, then deleted the originals on my laptop because I needed the space. Worked perfectly fine. So, my boyfriend unplugged the external hard drive from my computer. When I plugged it back in, the music played fine, but after I updated my iPhone software, I began getting the "!" next to all of my songs, indicating that the file path is no longer valid. iTunes then proceeded to delete all of my music, none of which is in my recycle bin. The strange part is, in my external hard drive, all of my folders and files are still there, but no matter what I do, none of the files show up in my iTunes library. And yet, they are still on the external hard drive. Any ideas as to what is going on and how I can get my music back onto iTunes...? p.s. - sorry for the long explanation.
