I love kyroflux for the 300 rainbow floppies I just did. But you'll need a
supported drive, and the more exotic formats are dicier on main-stream
drives, though even the flippies work. And you can store it as flux
transitions, raw track data or arrays of sectors when reading data. I
thought I'd need that for the rainbow disks, but only the 123 disks had any
kind of odditiy as copy protection, but there's patches to cope with that.

There's a MFM emulator that also reads MFM hard disks.
https://www.pdp8.net/mfm/mfm.shtml is what I've used to image a couple of
MFM hard disks that I have. It also emulates MFM drives, which makes it
easy to switch between Venix and MS-DOS on my Dec Rainbow.
