Generate IPF from raw KF stream ("Failed to probe input file")

[TiBeN]

Hi,

I would like to convert a raw KF stream image to IPF. I just discovered this tool which seems to handle this but can't make it works. I have a set of Kryoflux track*.*.raw files which seems to be supported by disk-analyze.

I tried the dumb approach of executing:

$ disk-analyze ./track00.0.raw ./myoutput.ipf

but disk-analyse outputs:

Failed to probe input file: ./track00.0.raw

Source is an IBM PC floppy image (fetched somewhere from archive.org, i can give links if needed).

I'm sure i don't use the tool like it is supposed. How this tool is supposed to work with KF raw images as input ? I can't really find any examples or documentation.. I tried with ./*.raw as input file as well with same result. I tried another set of raw files. These files are correctly read using DTC (Kryoflux tool), HxC Soft, Aufit tools, so they are not corrupted.
I compiled myself disk-analyse with capsimage and tried the Arch Linux AUR package version as well (i'm on Arch.)

EDIT: Tried using "-f ibm_mfm_dd" as well

Thanks in advance

Sorry, with disk-analyse you specify the KF stream filename "stem". In this case ./track

But the tool will only generate a useful IPF if the disk format is fully understood. That's okay if your disk is a regular PC disk (say 720k or 1.44M for example). But if it's copy protected you're out of luck because disk-analyse doesn't know any PC copy protections -- it's a quite an Amiga-centric tool.

For a regular non copy-protected disk this should work for you

$ disk-analyse --format=ibm ./track ./myoutput.ipf

Okay , i was pretty convinced it was an cmd input issue. Its works now. Thank you for your quick answer.

Yeah you are right that's pretty what i'm trying to do: reproducing a copy protected IBM PC disk. I'm really discovering this wonderful world and i may be completelly wrong as i'm far from mastering every aspects. But if i know that a specific sector has "weak bits", is it possible to tell to disk-analyse that a specific sector is weak ? (it seems IPF specification supports this).

Sorry if what i say is wrong , i'm in the learning process to understand floppy storage..

There is a better tool for copy-protected "IBM sector" formats, and that is SAMdisk. Unfortunately it can't generate IPF, but it can generate EDSK, which is a useful format itself for some applications. Yes it would be great if disk-analyse grew some general knowledge about a few of the common types of IBM-sector-based copy protection, but it doesn't have that currently and the only development on the tool currently is really filling in the gaps for Commodore Amiga.

ok. I'll take a look at SAMdisk. Thank you for your feedback.
