I don't think anyone has an issue w/native 4KB sectors and operating
system support for it. That would have been the big win. What folks
have issue with is the hybrid 512/4096 drives which has created the
alignment offset problems.
The industry (BIOS/firmware), commercial and FOSS OSes, should have
worked together to migrate directly to 4KB native sectors. I don't know
why this didn't happen, usual suspects I guess. It seems, from my
limited POV, that the Linux partition tool people and kernel folks
simply don't care at this point.
I've not paid recent attention. Have fdisk, cfdisk, parted, etc, all
come up to speed now, and automatically handle offsets correctly for
hybrid sector size disks?
