I have talked to Symantec about the D1 and they seemed very familiar.
(Meaning I didn't even need to finish describing the problem) Anyway,
the D1 seems to be a "bad block"-type error--he recommended Disk First
Aid straight off the Apple disks.  And sure enough, DFA found a
problem, fixed it and TuneUp-Optimize worked perfectly.

FYI-TuneUp from SUM has two types of tuning up: Defragmenting all
fragmented files and "optimizing" up the volume which involves making
all space used/unused contiguous.  (This is where a D1 can come from)

And a note the person who asked if DFA ever did anything--it sure 
did here...
