Thanks to all for looking.
Apparently it is not a wide spread defect.
Doug - The shot of the defect is from a Tiff that was made directly from the
RAW capture (DNG).
On other images, the black line (column) is constant in width & color.
I've printed off the mailing label & boxed the body - I'll mail it tomorrow.

That is really, really weird.
That is really strange. Is the lower crop from PEF or JPG? Is it full
one-for-one-pixel resolution from the original? The circular white part
looks entirely too circular. There's some curious artifacting inside the
black spot that's inside the white spot.
The black column seems to fade back almost to normal colors by the bottom
of the image, but to be about "full strength" at the top edge. If you zoom
in enough (like 10:1) you can see that the black line fades completely
away as it intersects with the white spot. The black could be from the
effects of a failure at one pixel on the pixels around it at either the
hardware or the software.
Can you shoot something like a Chromakey background (pretty uniform color
across the frame)? Can you provide an 800% or so zoom of the original
resolution that only includes that white spot, in GIF or PNG format to
avoid JPEG's machinations?
