I started a thread in the G75/G55 user forum with the steps to use the ASUS Recovery DVDs. Rather than double post, here's the link:
Step-by-Step: Using ASUS Recovery DVDs to Restore G75
Update: After serious testing across multiple G75VW users, we can confirm that the ASUS Recovery DVDs do NOT work on 1TB drives (regardless of manufacturer) if they are burned with the base AI Recovery Utility version that ships with the G75VWs. Make sure you install the latest version (1.0.24) BEFORE creating your Recovery DVDs.
