I'll do this tonight and send updated logs, thanks.

My power supply is well over-sized for my machine (Antec 480W), so that
shouldn't be a problem. I double checked all my SATA data and power cables.
I also tried switching from SATA-power to PATA-power cables (my drives
support both) to see if that made a difference (it didn't). I've reseated my
cables, switched cable order, etc. to see if I had a bad cable, but no
evidence I do.

Understandable. I saw several reports like that on the list, and hence tried
the above.

Thanks for your time, I'll get you updated logs tonight.
