I got the Hitachi HDT725040VLA360 dvd writer with my new vista computer http://h10025.www1.hp.com/ewfrf/wc/document?docname=c00821657&lc=en&cc=us&dlc=en&product=3339301. For some reason, it won’t read a lot of dvd-r and label them as new dvdr even though there are data on it. It also had trouble burning the ridata 16x dvd-r and hp 8x dvd-r, only the smart buy 8x dvd-r works on it. Is there any firmware that I can flash it with to fix this?
