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!

HMOUNT(1) General Commands Manual HMOUNT(1)
NAME
hmount - introduce a new HFS volume and make it current
SYNOPSIS
hmount source-path [partition-no]
DESCRIPTION
hmount is used to introduce a new HFS volume. A UNIX pathname to the volume's source must be specified. The source may be a block device or
a regular file containing an HFS volume image.
If the source medium is partitioned, one partition must be selected to be mounted. If there is only one HFS partition on the medium, it
will be selected by default. Otherwise, the desired partition number must be specified (as the ordinal nth HFS partition) on the command-
line. Partition number 0 can be specified to refer to the entire medium, ignoring what might otherwise be perceived as a partition map,
although in practice this is probably only useful if you want this command to fail when the medium is partitioned.
The mounted volume becomes "current" so subsequent commands will refer to it. The current working directory for the volume is set to the
root of the volume. This information is kept in a file named .hcwd in the user's home directory.
If the source medium is changed (e.g. floppy or CD-ROM disc exchanged) after hmount has been called, subsequent HFS commands will fail
until the original medium is replaced or a different volume is made current. To use the same source path with the different medium, reissue
the hmount command.
EXAMPLES
% hmount /dev/fd0
If a Macintosh floppy disk is available as /dev/fd0, this command makes the floppy current for other HFS commands such as hls(1),
hcd(1), hcopy(1), etc.
% hmount /dev/sd2 1
If a SCSI disk is available as /dev/sd2, this command finds the first HFS partition on the medium and makes it available for other
HFS operations.
NOTES
hmount does not actually mount an HFS partition over a UNIX directory in the traditional mount(8) sense. It is merely a "virtual" mount, as
a point of convenience for future HFS operations. Each HFS command independently opens, operates on, and closes the named source path given
to hmount.
