This is correct, you can only synch new music from iTunes to the iPod, not the other way around.

It's pretty easy though, just don't auto synch, mount the iPod as a hard drive, navigate through the folders. Just pull all the music to your hard drive and reimport into iTunes. You can then resynch to your iPod.

The music is stored in weird folder names on the iPod and they'll really make no sense, just just grab the top level. I'm sure this is documented on "unofficial" sites.

In the future, remember that iTunes is the master, not the iPod and don't reformat until you pull your music off.
