Write Error…
How can a solve that?
I have tried to upgrade the firmware to the newest… but it’s not useful…
Please help.~!!

Try better media. AML media is generally very poor and variable in quality.

I using 451 w/GS07/09 firmware
it is very good to write at 2.4X only. Write at 4X with nero / Sonic RN always can’t read TOC after write.

So AML only can be write at 2.4X on 451S, and pi/po is very high (~200/100) at the end of disk most of time (normal levle of pi/po on my sample is 20/5)
