Hi Terry. Thanks for getting back to me and confirming the number of disks in your N120 package. Make sure you don't make the same mistake I did and as soon as possible create a recovery snapshot of your netbook using the Samsung Recovery Solution software. If something goes wrong, you won't be able to reinstall the operating system as the disk you've got like mine only contains drivers and utilities that come preloaded with windows. All the best and I hope you like the netbook.
