Guys, skip 1.5 TB HDDs, nearly all of them are problematic, 1.5 TB is not such a "stable" (not sure how to put it that it would sound right...) manufacturing size for HDDs (unlike e.g. 640 GB which is so stable). Either stick to 1 TB or jump directly to 2 TB, although the current 2 TB HDDs aren't that good either...
