Try uninstalling your burning software and then re-installing it.
Try uninstalling your drive, restart, and let Windows install it.

Hello leslaw176, Your problem in your burning of DVD will be solve by just using other burning application like Nero DVD burner (which is the most stable and user-friendly software) software and by lowering your burning speed. There's an drop down menu before you burn you DVD which tells you what speed will be using try 16x in DVD. Its better to write normally than writing in full burst.
Their could be several possible reasons and solutions for the above error, basically what is happening is for some reason the CD/DVD burning software is unable to determine the Optimum Power Calibration rate (a small pre-burn test to determine optimal laser power for writing), resulting a disk burn failure. There is no easy way to pinpoint the exact reason, so try all the possible fixes from top to bottom (easy to hard) and see what works:
Try using different brands of quality blank media, most common reason for such error's is cheap blank media.
Try burning at lower speeds (Highly effective).
If this fails try a different burning software
Can you specify what these particular errors in question are? Assuming that these are read/write speed errors, changing the write speed settings to the slowest speed is your best option and is usually recommended for CD/DVD Authoring for less write errors.
Unlikely that there is a problem with the drive itself, most likely cause is software settings - which burning software are you using? if it is nero 6 then once you click burn after arranging the files for burning, the burn info page should pop up. click on the burn tab and make sure that "determine maximum speed" is checked and that write speed is set to maximum. hopefully this should solve it, if not try setting write speed to one of the slower settings listed and see if you get a better result. Sometimes dvd drives can slow right down when you are trying to push them to go at maximum.
if you want to check what it should be able to do, try http://www.pcpro.co.uk/reviews/87363/sony-dru820a.html
also worth trying is updating the drivers
to make sure you have the most recent version.
Another thing worth trying if you haven't already is try a different brand or type of disc - just occasionally there can be clashes with certain types and burners - if this seems to solve it, don't throw your pack of discs away, give them to someone with a different burner.
The final possibility is a power supply problem. If your PC's power supply unit has spare connectors for a drive then try a different one - possibly your supply doesn't have enough guts to run a more modern drive - take the drive out and try it in another pc with a higher power supply wattage rating.
Hope this helps :)
