That's a requirement in ancient DOS systems that use CHS addressing (physical CHS, no less), isn't it (so you can properly convert a within-partition address to a within-disk address)? While I would guess most people still partition disks that way (Even linux-util fdisk seems to do it by default), they don't have to. Doesn't matter for this discussion, though. As Doug demonstrated, even when you do start at cylinder boundaries, half your partitions start on an even sector, because typical cylinders have an odd number of sectors. - To unsubscribe from this list: send the line "unsubscribe linux-fsdevel" in the body of a message to majordomo@xxxxxxxxxxxxxxx More majordomo info at http://vger.kernel.org/majordomo-info.html
