gpart add -a 4096 vs 4k

[Irjohn Junus]

Hello,

Relatively new to FreeBSD and learning, I'm trying to partition my HDD and
align it to 4k sector.

I do apologize if this has been answered before, I have Googled and read
gpart(8) man page to no joy. Can anyone please advice why gpart add '-a
4096' doesn't yield the same result with '-a 4k'? Many thanks and captures
are below.

Regards,
Ronjns
