Plextor drives are known for providing quality measurements with the aid of the Plextools professional utility (the PX-740A is an exception to the rule), which as with all Plextor drive retail packages, comes as bundled software. We installed the bundled version of Plextools Pro version 2.19 on our system and tried to use the quality measurements features of the drive.

Unfortunately, the PI/PO Q-check feature is not supported by the drive, as well as all the advanced quality checks of the Plextools Professional Utility. The Plextools professional in this case, offers Digital Audio Extraction and Read Transfer Rate functions with this drive. Of course, you could use the EAC utility to extract from audio media, which would render the Plextools Professional in this case, unnecessary.
