Syncing an iPod may cause iTunes to freeze. That iPod is recognised and you get a set up iPod screen. When you select "Done", that iTunes program freezes.
You can download and install a most recent version of iTunes from Apple.
Click on an appropriate software version radio button. You can also uncheck those boxes next to an "Email me" and "Keep me up to date with" options, if you don't want email from Apple. Try to sync your iPod and hopefully that will resolve your problem.
If that does not work then you can try another option which is to reformat your iPod. In order to do this make sure all your files and songs on your iPod are already backed up. If your ipod is empty then please reformat your iPod.
Connect your iPod to your PC or Mac and iTunes will run and try to sync your ipod. It will freeze again. This time kill that iTunes software process, either by continually hitting an "X" to close that program or pressing your "Ctrl", "Alt", and "Delete" keys at same time.
A processes menu will open after pressing ctrl, alt, and delete. Highlight iTunes and select "End Process". Once iTunes is closed then go to "My Computer".
In my computer you will see a separate drive and letter for your iPod. Right click that drive and select format. This will erase everything on your iPod so please make sure you have all your files off your iPod backed up first if you have any.
Once your iPod is re formatted please try to sync it again with iTunes. These proceeding instructions were for a Windows computer. Substitute these appropriate commands and actions for your Mac.
