Trying to Create LDOS Model III Diskette

[toml_12953]

I use HxC to convert DSK images to SCP files. When I load an LDOS 5.31 for TRS-80 Model III into HxC, HxC correctly shows it as a 40 track single sided disk. When I convert it to an SCP file and load it into SuperCard Pro, it shows as a 20 track, double-sided disk. If I write it to a real floppy, it won't boot on a Model III. Is there a better way to convert DSK files to SCP? There are many cases where HxC doesn't create the output SCP expects.
