Why? Because early versions of MS-DOS couldn't load IO.SYS if the first
couple of sectors crossed a track boundary. That, plus it was a way to
improve performance back when tracks actually meant something.
Note that there is a lot of braindead software, including Grub2, which
makes assumptions that the first N sectors after the MBR are free.
These days we should align to a large enough power of two, 32K minimum.
