Quick iTunes Question

[The Toon Master]

when you plug your iPod in the computer, it scans your iTunes file ,and occassionally it will pop with stuf f that can't be found on your iPod. I was wondering how i can do that without plugging in my iPod so i can fix those before i update my iPod

Well I haven't found a definite way of finding out which files are missing/broken.. but when my iPod tells me that error in iTunes, i just jot it down and then i find them manually...
i know it sounds like a pain.. but i dont know any other way to do it...
maybe someone else does?
