Of course you are not the only one. But the real answer was to be found in another random stackoverflow forum: When you have 512 octets logical sectors and 4096 octets physical sectors, you really have eight logical sectors in a physical one, it matters to align the small ones inside the big ones. But with blocks of flash memory, there is not constant nor regular mapping of sectors to blocks, so the information about the block size is not useful outside of the disk controller.
