1. So no one has duplicated techvslife's corruption issue? (though i believe it's real). How about uninstalling Intel's drivers to rule out? 2. As an aside: As a non-Mac owner I've heard Apple does use Samsung 830 SSDs in their recent laptops, and that Apple supports some form of GPT. Wouldn't that combo present with problems? 3. I'm glad I haven't gone ahead to play with GPT on my 830.... (though I'll look into whether Plextor has done better).
