iPod touch syncing problem

[iMore Question]

When I try to sync my iPod touch, the computer tries to download my entire library again not just the changes that I have made causing the message 'iPod needs more space'. It's a new problem? Been syncing for years OK.

When you open the device page in iTunes, go to the music section and make sure "Sync entire library" isn't checked
