hi, i have a 4th gen 32 gb ipod touch. Everytime that i plug it in to my computer and itunes poppes up, an error message comes up too that says something like "this device has been synced with another itunes account. do you want to erase and sync with this itunes account? so i click yes, and it starts the sync. then it says all of the info could not be recovered.... so i hit okay. then it continues syncing but after it is done, i only have 229 songs but in my library i have over 300 songs. I have plenty of space left, so memory isnt an issue. I have also gone to the music tab under my ipod and made sure that sync all songs was checked, then i synced again and still had same problem. hopefully someone can help me out! thanks.
