PowerRec on Mac?

My computer: PowerMac G4,
My plextor: PX-W5224TA
My OS: MacOS X 10.2.8

How can I know whether my plextor’s PoweRec is ON or OFF? When I installed the drive on PC for firmware update, I have confirmed PoweRec was ON(default). I never touched anything.

So, PoweRec is enabled on mac?

By default PoweRec is enabled for the drive. I see no reason why it should be different for the Mac.
