With my iPod Classic 80 giga (I have about 40 giga of podcast and 40 giga of music) I unchecked Sync in the podcast Tab (and clicked apply) . The podcast icon disapperad from under the iPod. If i want to sync podcast again I have the warning message : you don't have enough space on your iPod to sync the checked podcast! This happens because the podcast are still on my iPod but not in the podcast library. 40 giga of the iPod are occupied by podcast but i don't find them!!!!!!!!!!
