No, it's older versions that use 63, while the new fdisk uses 2048. This
way the new 4K sectors of huge drives are aligned well. It does not
need to be 2048, as long as it's dividable by 8. But fdisk apparently does
not allow smaller values.

I thought this would work, but I'm not sure now. But why do you want to
change the partition start anyway?
