fdisk for [[Mach (kernel)|Mach Operating System]] was written by Robert Baron. It was ported to [[386BSD]] by Julian Elischer,<ref>{{cite web|url=https://www.freebsd.org/cgi/man.cgi?fdisk|title = Fdisk}}</ref> and the implementation is being used by [[FreeBSD]],<ref name=f>{{cite web |url= http://bxr.su/f/sbin/fdisk/ |title= fdisk — PC slice table maintenance utility |website= BSD Cross Reference |publisher= [[FreeBSD]]}}

For native partitions, BSD systems traditionally use [[BSD disklabel]], and fdisk partitioning is supported only on certain architectures (for compatibility reasons) and only in addition to the BSD disklabel (which is mandatory).
