Disk Utilities

A collection of utilities for ripping, dumping, analysing, and modifying disk images. All code is public domain (see the COPYING file).

Targets Linux, Mac OS X, and Windows (using Cygwin or MinGW), and should be very POSIX portable. amiga-native/ targets classic Amiga m68k, tested with SAS/C 6.50.

Prerequisites: You need at least Make and a C compiler (GCC; for Clang you'll have to edit CC in Rules.mk). On Mac OS X, the Xcode Command Line Tools include this. On Windows, you need Cygwin/MinGW, Make, and a C compiler.

Building & Installing:

  # make clean
  # make
  # sudo make install

Tomse has made a beginners' guide for building Disk-Utilities on Windows 10 using the Linux Subsystem.

IPF & CT Raw support: The CAPS/SPS IPF support library

If you wish to read IPF and CT Raw images with disk-analyse then you must explicitly configure support by specifying caps=y in the build process.

  # make clean
  # caps=y make
  # sudo caps=y make install

Your build may now fail with an error similar to "caps.c:12:28: fatal error: caps/capsimage.h: No such file or directory". This error occurs if you do not have the CAPS library header file in /usr/include/caps. In this case you must download and install as follows:

  # wget -O ipflib42_linux-x86_64.tar.gz http://www.softpres.org/_media/files:ipflib42_linux-x86_64.tar.gz
  # tar xf ipflib42_linux-x86_64.tar.gz
  # cd x86_64-linux-gnu-capsimage
  # sudo cp -a include/caps /usr/include

You must also have v4 or v5 of the CAPS library installed (v5 is required for CT Raw image support). Failure to install the library will result in an informative error message when you attempt to read a CTR or IPF image. You can download, build and install v5 of the support library as follows:

  # wget http://www.kryoflux.com/download/spsdeclib_5.1_source.zip
  # unzip spsdeclib_5.1_source.zip
  # unzip capsimg_source_linux_macosx.zip
  # cd capsimg_source_linux_macosx/CAPSImg
  # chmod u+x configure
  # ./configure
  # make
  # sudo make install
  # cd /usr/local/lib
  # sudo ln -s libcapsimage.so.5.1 libcapsimage.so.5

Library search path ("error while loading shared libraries: libdisk.so.0"):

Note that libdisk.so will need to be on the run-time linker's search path for many of these tools to run. There are a few ways to ensure this:

  1. Use LD_LIBRARY_PATH on Linux, DYLD_LIBRARY_PATH on Mac OS X, or PATH on Windows. This environment variable specifies a set of paths for the linker to search. So, to run disk-analyse without running 'make install', you could run it as follows:
  # LD_LIBRARY_PATH=libdisk disk-analyse/disk-analyse # Linux
  # DYLD_LIBRARY_PATH=libdisk disk-analyse/disk-analyse # Mac OS X
  # PATH=$PATH:`pwd`/libdisk disk-analyse/disk-analyse # Cygwin
  1. Install to a location on the system-wide search path. If the default install location for libdisk (/usr/local/lib) is not searched by default then you will need to add the path to /etc/ld.so.conf (or to a file in /etc/ld.so.conf.d/ in some Linux distros). For example:
  # echo "/usr/local/lib" >>/etc/ld.so.conf
  # ldconfig

You should now be able to run disk-analyse and other tools just fine.

Brief Descriptions:

disk-analyse/ Disk image conversion tool.

  • Read-only support: * Kryoflux STREAM * DiscFerret (.DFI) * Amiga diskread (.DAT) * SPS/CTRaw
  • Read/write support: * SPS/IPF * ADF, Extended ADF * LibDisk (.DSK) * Supercard Pro (.SCP) * ImageDisk (.IMD) * Sector Image (.IMG) * HxC Floppy Emulator (.HFE) (orig,v3)

libdisk/ A library for converting and manipulating disk images. It can create disk images in a range of formats from Kryoflux STREAM and SPS/IPF images (among others), and then allow these to be accessed and modified.

adfbb/ Read/modify/write ADF boot blocks. Mainly I use for stuffing bootblock sectors and recomputing the checksum.

adfread/ Read file contents of an ADF and optionally dump into local host filesystem

adfwrite/ Stuff data into selected sectors of an ADF image

amiga-native/diskread Dumps a disk to a (large, 20MB!) file. Really you need an Amiga equipped with PCMCIA-CF for this to be useful.

m68k/ m68k/ M68k disassembler/emulator library. amiga/ Amiga emulator (very limited, sufficient to run track loaders and protection routines). disassemble Example utility for disassembling raw binary files copylock Run a given RNC Copylock routine in emulated environment, copying decrypted code to a shadow buffer for subsequent disassembly and dump

ipfinfo/ Dump information about an SPS/IPF image file.

scp/ Dump floppy flux data from Supercard Pro to a .SCP image file.
