Load a DVD-ROM into the DVD drive before running this test or the test will fail.
When a DVD-ROM is loaded in the drive, SunVTS uses the dvdtest to test the drive. When a CD (non-DVD type) is loaded, SunVTS uses the cdtest to test the drive. Whenever you change the media in the drive you must perform a reprobe (refer to the SunVTS User's Guide for details) so the SunVTS kernel will associate the correct test (dvdtest or cdtest) based on the media that is loaded in the drive.
