Clem,
Thanks for your help. You’ve correctly interpreted my question.
Is the disk image independent from the disk hardware? I’d assume that
different disks may have different block sizes etc, so the disk type may be
important.
The target system is LSX, a cut-down version of V6 designed to run on the
LSI-11. There are very few system utilities in the standard build (no mount
for example). The second floppy is permanently mounted at boot time. I’m
interested in making source file floppies on my modern system to use on the
LSX, so I want to be able to create an image file from a source folder tree.

Is there a Windows or Linux utility to create a
disk image in any of the
above formats, from a local folder tree?
What I think you are asking, is there a utility for a modern OS that will
walk a local folder tree on my OS and create a new file whose structure is
that of the file system for OS <insert yours here>.
The issue is not the device as much as the OS and disk file layout. As
far as UNIX (or simh at the OS level) is concerned, the disk is just a
linear array of bytes, addressed by blocks. The physical format is not
seen by UNIX.
There are numerious utilities, as well as 'foreign file systems' that are
available. For instance, many Unix's can write RT-11 and MS-DOS format
with standard utilities. It really depends the OS. That said,
if the target OS is modern enough to support NFS or Samba, the easiest way
might be export the file system from local system, and then running a
simulated OS, 'mount' the file system.
