I backed up my HD, but itunes lost songs. Help?

On HD #2 itunes has exclamation points. I pointed itunes to the new hard drive in "advanced." Based on internet advice (CNET), I configured the library - no improvement. I can find one song at a time, but there has to be a faster way?

Thanks in advance.

Clear your library and reload it from the file that contains all of your music.
The exact same thing just happened to me...exactly. Before I began to search for a solution, I downloaded the latest versions of iTunes and some Microsoft updates and the problem just went away. I don't know why. I don't know how. That's about all the help I can provide.
Are you using Mac or Windows?

If you are using Mac, please read my post in this thread


Don't follow CNET on this one. They don't know what they are talking about.

If you are using Windows, there is a similar solution but it will take a bit more work. If you are interested, I can walk you through but I need to know which version of Windows you are using first.

I have been using external HD with iTunes on both OS/X and Windows XP Pro for over 3 years, never lost a file.
