Answers & Comments
Are you actually getting a message regarding OPC?
I'm not sure we can determine which CD drive is exhibiting the problem from what is given, if that's what your Question #1 is about.
Answer #2: If the problem appears at initial calibration of the new disc, try a different (or cleaner) disc. BTW: did you start using a different brand or type of disc in the middle of this?
These links lead to some technical info about what OPC is.

Running Optimum Power Control (Running OPC)
A technique used by recorders for monitoring and maintaining the accuracy of all the
mark and land lengths across a CD-R disc.

The CD Recorder does some sample write testing at the beginning of a disc to get a bead on how much laser power it needs to use to make reliable 'ones and nones" on the media. It records the settings in memory. Throughout the recording it monitors surface relectivity and compares it against the test data and in many cases can compensate on the fly for changes.
My read on this is that it may be trying to tell you on any given recording that it has reached or surpassed its effectiveness limit.
Appreciate the feedback and any other details you can provide later. I learned something in this, too.
As the article states, even within a given pristeen disc there can be variations that require modifications to its operating spec. Sometimes the machine will even reduce its speed to get back in spec. What brand are we talking about?
