Don't be ridiclous, there's no reason for it to be a memory wipe, they got dumped in the middle of the desert with no prior knowledge of where they were. There is no doubt billions of deserts on billions of worlds.
If you were suddenly dumped in a desert following a terrifying battle i doubt you could tell the diffrence between the Sahara Desert and the Gibson Desert for example
to why Owen doesn't recognise 3PO... there are probably millions of protocol units with the same annoying voice. besides, 3PO had silver plating and now gold.
And perhaps he DOES recognise him. He says "you, I take it you're programmed to ...", of course, he did it a few movies earlier but perhaps he knew 3PO had the wipe and thought it was save to buy him (hey, he does need someone who speaks Bocce)

ahhh but what alot of ppl missed is that when owen purchases 3po he says his first job was programing the same type of machines, alot of ppl thought they would see that in ep III, but wouldnt his first job have been when he and shmi went to work for cliegg w/primary load lifters, maybe it was not a complete memory wipe
