Ipod and Itunes

[kfc469]

My computer died and I lost everything that was on my hdd. I have copied all of my music back to my computer from my ipod by showing hidden folders and then copying and I imported them into itunes. But, none of my ratings or playlists are there. My question is: If I sync my ipod with my computer now, will it update all of my ratings/ playlists on the computer, or will it erase them from the ipod?

Thanks
