Yesterday I read another analysis of what seems to be the same drive which tried to verify the real capacity, but the issue was that the drive was throttled to a low-speed connection so that validating it by writing and re-reading the full volume of data would take something like 250 days. So it's kind of obvious that it was bad, but you can't easily prove it in a reasonable time.
