Unfortunately there is no simple solution given that we can't go back in time and fix legacy DOS/XP behavior. The 1-alignment jumper (that some drives have) fixes things for the first partition but will mess up our alignment for subsequent ones unless the firmware actually reports the shift. So no matter what we do the user will have to have a bare minimum of knowledge about 512-byte LBS/4 KB PBS drives. That sucks. But even Windows users are presented with extra documentation and alignment utilities during the transition. Having a 1 MB alignment by default and hoping that devices that lie will be 0-aligned is the best we can do, I think. -- Martin K.
