you are getting it to work on a mac yet its formatted for a pc?? doesn;t make sense if thats the case
if you still have a pc or you are getting the "mixed results" on a pc - good
hook it up to a pc and set it to show hidden folders, drag and drop the folder from the iPod onto the pc desktop
reformat on the mac
burn a dvd of the music folders on the desktop
rip the folders on the mac from the dvd
import to iTunes

if on a mac try "senuti"
