I have a itunes installation where several (hundred) tracks are missing, you can't tell this until you come to play them. This is all basically due a crashed HDD and what would appear to be a duff itunes index. How do I go about getting itunes to see an accurate picture of all the music I have? I thought of deleting the itunes directory (the music is located in a different disk area) and reinstalling itunes and getting it to scan of music - anyone dones this? any problems?
