blkid command will display the UUID of all your partitions.

You have to edit the /etc fstab file on your new partition, not the old :).

You also have to fix /boot/grub/menu.lst (because you are changing the
root drive)

And finally, you will then have to run grub-install on your new drive,
then you should be ready to remove the old hard drive and verify that
your system can boot with the new one by itself.
