Спасибо! 

Действительно, при
cdrdao simulate --device 0,0,0  --driver generic-mmc data.toc
и при
cdrdao simulate --device 0,0,0  --driver generic-mmc --speed 8 data.toc
симуляция прошла успешно.


Запись диска на 8 скорости -- тоже успешно. 
Команда:
cdrdao write --device 0,0,0  --driver generic-mmc --speed 8 data.toc
диск CD-R TDK.

  Write speed # 5:  1411 kB/s CLV/PCAV (CD   8x, DVD  1x)

---------------------

Т.е., как я понимаю, 8x - минимально возможная скорость записи CD-R
для этого привода.


Так что да, cdrdao на Plextor PX-800 диски на скорости 8x
записывает, а cdrecord -- нет.
