Tip T5304 - your drive is HD DVD capable. To test its performance, use a test HD DVD disc.
Fix: Use the Sandra test DHD VD or a compatible disc.
NB. Commercial HD DVD discs (movies, etc.) cannot be used in general as they are encrypted thus cannot be read. If you do not have the Sandra test HD DVD you will need to burn yourself one.
