I'm trying to preserve my Acorn ADFS 3.5"
discs. To this end, I've purchased a KryoFlux "Pro" board and a
new-old-stock ALPS floppy drive.
I've hooked it all up to a Windows 8.1 VM and everything *seems* to be working.
However, the .adl images I create are all 0KB in size.
A 0kb file - or one smaller than expected - means that the DTC program
was not able to make sense of some (or in this case, all) of the flux
transitions in terms of the format you selected. If I don't know what
I'm dealing with, I found it useful to read the disk in "raw" mode
first (where it makes a large file for each track) and then set DTC
against those flux files until I found the right combination of
settings to produce an image. A lot less wear on the disk and drive
vs. attempting to translate on the fly and failing a lot. You'll want
to get to know the command line options intimately - the GUI can't do
it all.
Their forums are very useful for sorting out disk format details -
whatever you're reading, there's usually someone who has tried before
and gotten help. Here's a post on Acorn ADFS:

(I know nothing of Acorn, so that may not be what you're trying to do.)
All DTC settings matter. In many cases, the order of the settings
matter, a lot. I've spent many hours banging my head against the
desk, only to find I had switched to flags around.
