https://bugs.freebsd.org/bugzilla/show_bug.cgi?id=3D274312 --- Comment #4 from Andrew "RhodiumToad" Gierth <andrew@tao11.riddles.org.u= k> --- Incidentally the 2014 discussion seems to be claiming that that the spec doesn't give a hard lower bound on the table size. This is incorrect: the s= pec (UEFI version 2.9, section 5.3.1 "GPT Overview") says: A minimum of 16,384 bytes of space must be reserved for the GPT Partition E= ntry Array. If the block size is 512, the First Usable LBA must be greater than or equa= l to 34 (allowing 1 block for the Protective MBR, 1 block for the Partition Table Header, and 32 blocks for the GPT Partition Entry Array); if the logical bl= ock size is 4096, the First Useable LBA must be greater than or equal to 6 (allowing 1 block for the Protective MBR, 1 block for the GPT Header, and 4 blocks for the GPT Partition Entry Array). --=20 You are receiving this mail because: You are the assignee for the bug.=
