How can I test my PX-810SA in DiscSpeed?

I have bought a Plextor PX-810SA two weeks ago.
But,when I tried to test Disc Quality,no disc quality check capability~
I can’t choose the title…And ,when I remove the registry
“HKEY_LOCAL_MACHINE\SOFTWARE\ahead\Nero Toolkit\CD speed\CD Quality”
then remove all the value in “Blocked” ,disc quality check was still blank~~

How can I solve my queston :sad:
Please help me,thanks a lot :flower:

Even if you can get it working, it won’t be of much use as the 810SA is just a rebadged Pioneer DVR-212, and Pioneers aren’t very reliable for error checking.

The Pioneer DVDR-212B and the Plextor PX-810SA (OEM-212) do not support quality checks.

Those DVD burners don’t support disc quality checks…ok
Thank you all…
