I have two drives which report the same "firmware revision", but one has the -6 in the model number and the other doesn't. The one with the -6 reports 4096B sectors, the other does not. I think WD is simply using the wrong field for firmware revisions, as there are other apparent firmware differences between my two drives, despite them having the same "firmware revision" numbers. Gotta love WD.
