After formatting an external hard drive with OS X's diskutil, the disk is automatically split into 2 partitions like so:
Finished partitioning on disk1 /dev/disk1 #: TYPE NAME SIZE IDENTIFIER 0: GUID_partition_scheme *500.1 GB disk1 1: EFI 209.7 MB disk1s1 2: Apple_HFS Milosz Pass 499.7 GB disk1s2
Now, since this is my external HDD that's not using for firmware upgrades/booting or whatever the EFI partition might be used for, I assume I might as well delete it and use the extra 200MB for something else. But how do I do that?
Using diskutil partitionDisk and explicitly stating that I only want 1 partition to be created, it still creates the EFI partition alongside the other one. Any hints I was able to find so far described how to do this under Windows, but surely there must be a way to do this on OS X as well.
