It's just simply a matter of Windows XP, being really ancient, doesn't create properly alligned partitions by default. And how often are we going to see Windows XP systems with these new 4k physical sector drives anyway, where the first OS to touch the partition is Windows XP? And in the case where this does happy, the resulting partition will be result in terribly performance for Windows XP as well as Linux. What's the specific scenario which you are trying to solve, and how likely is it to occur in real life? - Ted
