I would agree with this. Though, it is possible through mental exercises
like meditation to focus attention and raise some of the lower level data
up to a more conscious level.

It may be that you know, but you don't know that you know.
At least some people working on the brain believe that those "magical"
feats (super-arithmatic, pictographic memories, etc.) may be present
in each of us. There may be no *meaning* behind the computation of the
square root of 2^79-1 or having a perfect mental image of a telephone
book page and being able to recall any of the numbers. If the above
interpretation of qualia is correct, then zombies, like idiot savants
are lacking the conscious image of self that makes them the central
player of the "movie in the mind".
However, if I recall, don't zombies experience pain or something
equivalent? If they do, even if it is much more slowly than normal
humans, then it would seem that they do have "qualia". Idiot savants
certainly feel pain. On the other hand profoundly depressed or
abused people, may be so desensitized that they may essentially
"feel" nothing. I suspect this may occur in some individuals
who undergo interrogation as prisoners of war. They certainly have
qualia but have detached the "movie in the mind" (and themselves)
from them.
I'm not sure that the filling in of incomplete pictures could be
treated as qualia. That is simply a difference mapping (a mental
"diff" for the computerphiles) of a sensory experience and a
collective built-in image of what one expects the image (sound,
feeling, etc.) to be. Since "differences" in some circumstances
may be very dangerous, this should be happening at a very unconscious
level with your conscious mind only seeing someone raising the red
warning flag.
