If you look at Jorg Schillings page for cdrecord you will note that there is 
a firmware upgrade for the Plextor PX-W8432T
http://www.fokus.gmd.de/research/cc/glone/employees/joerg.schilling/private/firmware.html

It is also referenced on the Plextor Technical support page
http://www.plextor.be/english/technical/download2.html

and the README for the upgrade specifically mentions this drive
http://makecd.core.de/ftp/FlashROM.readme

The only thing not mentioned is what the upgrade actually does?

I think we can probably conclude that you need to upgrade the firmware of the 
drive before it will work  :(
