My two favorite procedures are:
1) Do a complete disc clone, swap the drives, and boot from the installation CD. Do a Repair Install and that will fix the drives.
2) Do an image backup to an external drive with a tool like EASEUS ToDO Backup. Put the HDD in and restore the image to it with the option to Restore To Dissimilar Hardware checked. It will fix the drivers for you.
Thanks! I'll give method #1 a try (with my Win 7 USB instead of CD/DVD since this is a netbook, lol).
