can't convert DDI image to RAW correctly

[roytam1]

console shows:

Error: The data after the header is in a wrong format!

sample:
1.zip

old good unddi.exe source may help?
unddi104.zip

EDIT: maybe just removing JMP check is good enough, when the image is not FAT-formatted disk.

Hey @roytam1, thanks for reporting this. Does removing the jump instruction check (Lines 71-72) gives you a working image?
You are right, maybe it is better to give a warning and write out whatever is there after the header if the image does not seem to be FAT.
What image do you have there? Does it have signature bytes, so that it can be recognized? If yes, an additional check can be done. Then ddi2raw can inform the user which filesystem it actually found.

seems so.

What image do you have there?

some kind of old unix disks, so file system/BPB check is unuseful to these.

sure, DDI signature bytes are there.
