If you can dig up a DOS PC (FreeDOS should be fine but not an emulated or
virtualized DOS) with a SCSI adapter that's old enough to have a DOS ASPI
driver available, my PUTR.COM *should* be able to do it.  (Never tested
with non-512-b/s sectors, but it uses the sector size reported by the drive
rather than hard-coding for 512 so it should work.) and
the commands would be something like:

mount x: scsi1: /foreign
copy /file /dev x: image.dsk
