Hi, the model of the DVD-burner comes with my HP pc is HL-DT-ST DVD+-RW GSA-H21L W515, and I think the w515 refers to its firmware version.
some days ago, I just let my dvd-burner read a DVD video disc which has not been read sucessfully in many other dvd-rom drives or dvd-burners. then my dvd-burners keep reading all the time and the system was frozen. I had to shut down the power.
now I encounter a problem, the dvd-burner seems can only burn at 1X speed, despite of the setting speed of the burning tools, BTW I use nero 7. the time used before for burning a DVD at 8X speed is about 10 minutes, now the time is more then 40 minutes. I have observed the status light of the burner, it does not always keep on as before, now it will light on for a while then off for a while and on and off..... something like a buffer underrun, but I'm sure it's not due to buffer underrun. I have burned some cd-rs, and the speed is correct.
then I want to do something to its firmware. but to my surprise, all the firmware modulating tools tell that no target device found or model mismatched. HP's offical site has a update for model gsa-h21l, but the firmwire version is L702, the correspinding updating tool can't find target device either. strange!!!
has anyone encountered such a model? what can I do to my burner?
thanks in advance.
