Harry's mind doesn't seem to work this way.  Hermione has to remind 
him that he's already heard of Fenrir Greyback (from Malfoy in Borgin 
& Burke) when he tells her about the werewolf.  

The day in 12GP that Harry saw the locket, he also saw a number of 
other objects, some of which actually tried to 'attack', for example, 
the music box that put them all to sleep until Ginny slammed the lid 
shut.  These objects would probably stand out more in Harry's memory 
than one which did nothing.

Also, it was a year (more or less) since he saw the locket.  And Harry 
has not yet connected RAB to Regulus Black.  Once he makes that 
connection, he is sure to return to 12 GP.

Didn't Kreacher take the locket back to his nest when he 'saved' some 
of the items?  I think that Kreacher will be instrumental in finding 
and destroying this particular horcrux, whether or not he wants to...
