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: http://forum.kryoflux.com/viewtopic.php?t=849 (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.
