The Compatibility Test requires two high-density diskettes, either 5.25-inch or 3.5-inch. It will perform a short backup operation to confirm that your computer's hardware and the Norton Backup are 100-percent compatible with each other. It is highly recommended that you perform the Compatibility Test to ensure safe and reliable backups. After the Compatibility Test is complete, the Advisor will return you to the main menu.
