Vista - Insert blank CD/DVD, get numerous Event ID 51's?

I noticed that whenever I insert either a blank CD or DVD that the System
Log fills with, respectively, either 5 or 10 of these:

Event ID: 51
"An error was detected on device \Device\CdRom0 during a paging operation."

The Event Viewer help indicates it's just an informational message and no
action is required, but I'd like to know what's causing it since it's
filling up the log. It's obviously bogus, since there's not even any data on
the media and there can be no paging related to blank media.

The messages almost never appear any other time than when inserting media.

Burns do work (internal NEC/Sony AD-7170 on DMA and no PIO).

I did see a message long ago tying it to thumb drives or thumb drives used
with ReadyBoost, but I'm not using one.

I tried changing Vista's Autoplay behavior to "None" for blank media but it
had no effect on this problem.

I verified this before and since SP1 (Ultimate).

I get these same event messages - both before and after SP1. My CD drive seems to burn OK, but I've never been able to discover the cause of these events. Any ideas?

It's time to bring this topic back to light.

I'm getting this exact error. Thousands of them. There is nothing wrong with my hardware or device drivers at all. DMA is on and functioning, not PIO. CDs burn perfectly fine. Event Viewer just reads that Event ID 51 for no reason when inserting a blank CD.

Can anyone shed light on this? Thanks.

I'm getting the same issues. Insert a blank DVD+R in either of my 2 Pioneer DVD burner drives and hey presto, I get 4 paging operation warnings. They read and burn fine. Just live with the annoying alert log warnings I suppose. Doesn't appear to be faulty hardware at all.
