I wish it was left to people like myself. Realistically when it comes
to disks with 4096-byte logical sectors it going to matter how the
firmware chooses to expose it.
Most likely, the universe will explode at this time, since very few
bootloaders can deal with a sector size other than 512 bytes, and
virtually every partition table format contains a sector size
dependency, which also means you'll break any mechanical imaging solution.
It's going to hurt :(
