Plextor 716A CDRW read failure

Plextor 716A 1.04

New drive from RMA. Poor read with CDRW media and with some DVDRW media
I test it on two different machines. Some Idea

what kind of media

CDRW Verbatim - Philips
DVDRW Creation

Some of them with nero incd format and some other with normal write (single session)

I test 2 TDK DVDRW (one incd and one normal write) and it reads them.
