Yes, there is, but one that Windows doesn't understand because it is not
expecting it. The "mkisofs" early in the process. Linux is way more

oh yes, but it only copy the test hyerarchy in the iso, if this is an
linux file system, windows cat read it.

I think you misunderstand.

You create an iso image file on Linux somewhere. Then you dd that image
file to some other raw device, via dd to dev/sdg. This "dd" creates a
filesystem on sdg, same as if you'd run mkfs.iso on sdg directly.

Only that "mkfs.iso" does not exist, because of the particularities of
the iso "filesystem".

Compare with:

mkfs.ext4 somefile.img
dd if=somefile.img of=/dev/sdg

which is basically equivalent to:

mkfs.ext4 /dev/sdg

So the procedure Lew used effectively formatted his /dev/sdg as a DVD.
Only that Windows doesn't handle it, or not directly. It might via
acetoneiso or whatever.

If it doesn't, the procedure would be something like:

mkisofs -o test.iso <test-hierarchy>
mkfs.ntfs /dev/sdg
mount /dev/sdg /mnt/somewhere
cp test.iso /mnt/somewhere/test.iso
