Hi,
I've been working on upgrading the harddrive in a friends laptop for the sole purpose of adding another 30-40gb of music into his database. After getting the drive cloned successfully, I added a folder (55gb) of music into the the library with the "Add folder to Library" menu item. It took over 8 hours to process/convert the wma's into whatever they get converted too. However, it only added 2gb of music (400 tracks) into his collection. Is there any type of log / diagnostics for figuring out why the heck it's broken?

Or should I just remove iTunes and reinstall and let it scan again?

He does have a few playlists which have taken hours to setup for their bar, and if i loose them i'll be screwed.

His iTunes Music folder is 55gb currently, with 7500 songs, but iTunes only sees 4400 songs totally 33gb. Which is quite puzzling.
