Hi, Don. Thanks for getting back to me.
I have a drive which I use to install macOS 10.14 containing an HFS+ volume and a FAT32, custom EFI volume. I have an image of that installer drive which I'd like to restore onto a USB drive. I was able to accomplish a partial restore by using Disk Utility on my Mac to format and partition the USB drive. I then manually restored the HFS+ volume from the disk image, but received an error when trying to restore the FAT32 volume saying the volume couldn't be repartitioned. And that's as far as I've been able to get.
Using dd only restores the HFS+ volume and seems to ignore the FAT32 volume.
I'd like to use the command line to do a byte-for-byte restore of the image to the disk to accomplish my goal in one step, but I haven't been successful in finding such a method.
Let me know if you need more information. Thanks!

NAME
partx - telling the kernel about presence and numbering of on-disk partitions.
SYNOPSIS
partx [-a|-d|-l] [--type TYPE] [--nr M-N] [partition] disk
DESCRIPTION
Given a block device ( disk ) and a partition table type , try to parse the partition table, and list the contents. Optionally add or

This is not an fdisk - adding and removing partitions is not a change of the disk, but just telling the kernel about presence and numbering
of on-disk partitions.

-a add specified partitions or read disk and add all partitions
-d delete specified or all partitions
-l list partitions. Note that the all numbers are in 512-byte sectors.
--type TYPE
Specify the partition type -- dos, bsd, solaris, unixware or gpt.
--nr M-N
Specify the range of partitions (e.g --nr 2-4).
SEE ALSO
addpart(8), delpart(8), fdisk(8), parted(8), partprobe(8)
AVAILABILITY
The partx command is part of the util-linux-ng package and is available from ftp://ftp.kernel.org/pub/linux/utils/util-linux-ng/.
