I’ve been struggling with a syncing problem for a week.  I have a 60GB iPod and run iTunes 8.01 on a Mac Pro with Leopard 10.5.5.  I’d plug in the iPod and before it could sync the first file I’d get the error:

Attempting to copy to the disk <name> failed.  You do not have enough access privileges for this operation.  iTunes could not save to your Music Folder because you do not have write access.  Check the permissions on your Music Folder and folders in your Music Folder, then try copying this file again.

iTunes would then disconnect (not eject) the iPod and several other errors and warnings would pop up.  I searched and searched and tried many solutions but finally figured it out.  I needed to change read/write permissions on the iTunes Library file and iTunes Music Library.xml file — not for me, but for staff and everyone.  I did both at once so not sure which file did the trick or which role.

I documented my troubleshooting with a mind map.  It shows all of the things I tried and what eventually worked.  Hope it works for you, too.
