I think you will find that I said that some time ago... Everything has
been 4K aligned since the dawn of Vista, and whatever kernel release of
Linux was current about that time.


My own experience came with XP, which doesn't align partitions and
starts the first partition at sector 63. This pre-dates SSDs and AF
drives with the 4k block size.

The XP install I had was ok on a (non-AF) hard drive until I upgraded it
to Win7 and migrated the original hard drive contents to SSD by doing a
sector by sector copy using dd under a Linux boot CD.

This meant that I had a Win7 system on SSD with misaligned partitons
inherited from XP, incurring a performance penalty.

Hence my interest in correcting the misalignment by moving partitions to
a 4k boundary, which GParted did for me.
