Due to AFFLIB, I have to mention that:
This product includes software developed by Simson L. Garfinkel and Basis
Technology Corp.
1.0 What is xmount? - A short description
xmount allows you to convert on-the-fly between multiple input and output
harddisk image formats. xmount creates a virtual file system using FUSE
(Filesystem in Userspace) that contains a virtual representation of the input
image.
The virtual representation can be in raw DD, Apple's Disk Image format (DMG),
VirtualBox's virtual disk file format (VDI), Microsoft's Virtual Hard Disk
Image format (VHD) or in VmWare's VMDK file format.
Input images can be raw DD, EWF (Expert Witness Compression Format) or AFF
(Advanced Forensic Format) files.
In addition, xmount also supports virtual write access to the output files
that is redirected to a cache file. This makes it for example possible to boot
acquired harddisk images using QEMU, KVM, VirtualBox, VmWare or alike.
2.0 Input image support
Starting with version 0.7.0, input image support has been moved into external
libraries. The following chapters list the officially supported ones. They
might not all be available on your system though.
2.1 libxmount_input_raw
Supports raw DD images ("--in raw" or "--in dd").
2.2 libxmount_input_ewf
Supports EWF (Expert Witness Compression Format) images ("--in ewf") using
Joachim Metz's libewf (https://code.google.com/p/libewf/).
2.3 libxmount_input_aewf
Supports EWF (Expert Witness Compression Format) images ("--in aewf")
generated with Guymager (http://guymager.sourceforge.net/). This library
uses an EWF implementation written by Guy Voncken. It consumes much less
memory than libewf when mounting big (>1TB) images.
2.4 libxmount_input_aff
Supports AFF (Advanced Forensic Format) images ("--in aff") using Simson
Garfinkel's afflib (https://github.com/simsong/AFFLIBv3).
2.5 libxmount_input_aaff
Supports AFF (Advanced Forensic Format) images ("--in aaff") using an AFF
implementation written by Guy Voncken. In essence, it is a lot faster than
afflib.
3.0 Morphing support
Also starting with xmount version 0.7.0, a new concept of input image morphing
has been added. Morphing is a process which is applied to the data of all
specified input images and produces a single virtual image which can then be
converted into an output image. The following chapters list the currently
officially supported morphing libraries. As with the input image libs, not all
might be available on your system.
3.1 libxmount_morphing_combine
Using "--morph combine", data from all input images is concatenated into
a single image. Images are appended in the same order they are specified on
the command line. This morphing type is also the default if no "--morph"
option is specified.
3.2 libxmount_morphing_raid
This morphing library supports emulation of hardware / software raid.
Currently, only RAID0 ("--morph raid0") is supported. The used chunk /
stripe size in bytes can be specified with "--morphopts raid_chunksize=XXX".
All input images are treated as member disks of the original raid.
3.3 libxmount_morphing_unallocated
Using "--morph unallocated" it is possible to extract unallocated sectors
from a filesystem. For this to work, your input image must start with the
volume you want to extract unallocated sectors from. If you have an image of
a whole disk, you might need to use xmounts "--offset" parameter to move the
start of the data to the start of the volume. Currently, unallocated
sectors from HFS and FAT can be extracted.
4.0 Output image
4.1 Emulated RAW file
This is the standard data representation used by xmount. It is a file
containing the raw data contained in the input image file. Except for OSx
(see 4.2) this is the default output format when no --out option is
specified.
4.2 Emulated DMG file
This is also a file containing the raw data contained in the input image
file but with a .dmg file extension. On OSx, this is the default output
format when no --out option is specified.
4.3 Emulated VDI file
When using the "--out vdi" command line parameter, a VirtualBox disk file
is emulated. This means that xmount builds a virtual VDI header and prepends
it to the raw data contained in the input image. The VDI file can be used in
VirtualBox as a virtual disk file.
4.4 Emulated VMDK file
When using the "--out vmdk(s)" command line paramter, a VMWare virtual disk
file will be emulated. This mainly consists in building a VMDK descriptor
file that will access an emulated RAW file. You can use this VMDK file to
add your input image as virtual disk to a VMWare virtual machine. "vmdk" is
a VMWare disk attached to the IDE bus and "vmdks" is attached to the SCSI
bus.
When emulating VMDK files to be used in VMWare, you have to enable
"user_allow_other" in /etc/fuse.conf or run xmount and VmWare as root.
WARNING: VMDK support should be considered experimental and currently the
VMDK descriptor file isn't cached.
4.5 Emulated VHD file
When using the "--out vhd" command line parameter, a Virtual Hard Disk Image
file is emulated by appending to the raw data a valid VHD footer. Valid here
means as described in Microsoft's Virtual Hard Disk Image Format specs v1.
5.0 Virtual write access
By using the "--cache <cache_file>" command line parameter, xmount allows
you to change data in the emulated image files. All changes are written to a
separate cache file. No data will ever be written to the original input
image files! Write access is limited to change existing data. It isn't
possible to change the emulated image's file size (no append or truncate)!
The same cache file can be used with different output image formats without
loosing changed data.
6.0 Installation instructions
To install xmount, you can use a prebuild package for your distribution or
you can build xmount from source. The two methods are described in the
following sections.
6.1 Prerequisits
SYSTEM:
- Linux: Some sort of Linux with a recent kernel (2.6.x or above).
- OSx: OSx 10.6 or above
FUSE:
Your OS must support FUSE and have the appropriate libraries installed.
(See http://fuse.sourceforge.net/ for more informations). On OSx, you can
use OSXFuse (https://osxfuse.github.io/) as replacement. To be able to
install from source, you also need the FUSE header files.
LIBEWF:
To enable EWF input image support. Get it from
http://sourceforge.net/projects/libewf/
LIBAFF:
To enable AFF input image support. Get it from http://www.afflib.org/
6.2 Install from a package
Chances are I provide prebuild binary packages for Debian / Ubuntu and OSx.
In this case, you only have to fire up your distribution's package manager
and install xmount. See https://www.pinguin.lu/xmount for more information
and download links.
6.3 Install from source
After having checked the prerequisits, you should be able to compile and
install xmount by simply issuing the following commands:
$ mkdir build
$ cd build
$ cmake -DCMAKE_BUILD_TYPE=Release ..
$ make
$ sudo make install
7.0 xmount usage examples
To xmount an EWF harddisk image from your acquired disk as a raw DD image
under /mnt, use the following command:
xmount --in ewf ./acquired_disk.E?? /mnt
To xmount the same ewf image as vdi file, you would use a command like this:
xmount --in ewf ./acquired_disk.E?? --out vdi /mnt
And to enable virtual write support on a raw DD input image xmounted as VDI
file:
xmount --in raw ./acquired_disk.dd --out vdi --cache ./disk.cache /mnt

/*
----- Change log -----
20090131: v0.1.0 released
* Some minor things have still to be done.
* Mounting ewf as dd: Seems to work. Diff didn't complain about
changes between original dd and emulated dd.
* Mounting ewf as vdi: Seems to work too. VBox accepts the emulated
vdi as valid vdi file and I was able to mount the containing fs
under Debian. INFO: Debian freezed when not using mount -r !!
20090203: v0.1.1 released
* Multiple code improvements. For ex. cleaner vdi header allocation.
* Fixed severe bug in image block calculation. Didn't check for odd
input in conversion from bytes to megabytes.
* Added more debug output
20090210: v0.1.2 released
* Fixed compilation problem (Typo in image_init_info() function).
* Fixed some problems with the debian scripts to be able to build
packages.
* Added random generator initialisation (Makes it possible to use
more than one image in VBox at a time).
20090215: * Added function init_cache_blocks which creates / loads a cache
file used to implement virtual write capability.
20090217: * Implemented the fuse write function. Did already some basic tests
with dd and it seems to work. But there are certainly still some
bugs left as there are also still some TODO's left.
20090226: * Changed program name from mountewf to xmount.
* Began with massive code cleanups to ease full implementation of
virtual write support and to be able to support multiple input
image formats (DD, EWF and AFF are planned for now).
* Added defines for supported input formats so it should be possible
to compile xmount without supporting all input formats. (DD
input images are always supported as these do not require any
additional libs). Input formats should later be en/disabled
by the configure script in function to which libs it detects.
* GetOrigImageSize function added to get the size of the original
image whatever type it is in.
* GetOrigImageData function added to retrieve data from original
image file whatever type it is in.
* GetVirtImageSize function added to get the size of the virtual
image file.
* Cleaned function mountewf_getattr and renamed it to
GetVirtFileAttr
* Cleaned function mountewf_readdir and renamed it to GetVirtFiles
* Cleaned function mountewf_open and renamed it to OpenVirtFile
20090227: * Cleaned function init_info_file and renamed it to
InitVirtImageInfoFile
20090228: * Cleaned function init_cache_blocks and renamed it to
InitCacheFile
* Added LogMessage function to ease error and debug logging (See
also LOG_ERROR and LOG_DEBUG macros in xmount.h)
* Cleaned function init_vdi_header and renamed it to
InitVirtVdiHeader
* Added PrintUsage function to print out xmount usage informations
* Cleaned function parse_cmdline and renamed it to ParseCmdLine
* Cleaned function main
* Added ExtractVirtFileNames function to extract virtual file names
from input image name
* Added function GetVirtImageData to retrieve data from the virtual
image file. This includes reading data from cache file if virtual
write support is enabled.
* Added function ReadVirtFile to replace mountewf_read
20090229: * Fixed a typo in virtual file name creation
* Added function SetVirtImageData to write data to virtual image
file. This includes writing data to cache file and caching entire
new blocks
* Added function WriteVirtFile to replace mountewf_write
20090305: * Solved a problem that made it impossible to access offsets >32bit
20090308: * Added SetVdiFileHeaderData function to handle virtual image type
specific data to be cached. This makes cache files independent
from virtual image type
20090316: v0.2.0 released
20090327: v0.2.1 released
* Fixed a bug in virtual write support. Checking whether data is
cached didn't use semaphores. This could corrupt cache files
when running multi-threaded.
* Added IsVdiFileHeaderCached function to check whether VDI file
header was already cached
* Added IsBlockCached function to check whether a block was already
cached
20090331: v0.2.2 released (Internal release)
* Further changes to semaphores to fix write support bug.
20090410: v0.2.3 released
* Reverted most of the fixes from v0.2.1 and v0.2.2 as those did not
solve the write support bug.
* Removed all semaphores
* Added two pthread mutexes to protect virtual image and virtual
info file.
20090508: * Configure script will now exit when needed libraries aren't found
* Added support for newest libewf beta version 20090506 as it seems
to reduce memory usage when working with EWF files by about 1/2.
* Added LIBEWF_BETA define to adept source to new libewf API.
* Added function InitVirtualVmdkFile to build a VmWare virtual disk
descriptor file.
20090519: * Added function CreateVirtDir implementing FUSE's mkdir to allow
VMWare to create his <iname>.vmdk.lck lock folder. Function does
not allow to create other folders!
* Changed cache file handling as VMDK caching will need new cache
file structure incompatible to the old one.
20090522: v0.3.0 released
* Added function DeleteVirtFile and DeleteVirtDir so VMWare can
remove his lock directories and files.
* Added function RenameVirtFile because VMWare needs to rename his
lock files.
* VMDK support should work now but descriptor file won't get cached
as I didn't implement it yet.
20090604: * Added --cache commandline parameter doing the same as --rw.
* Added --owcache commandline parameter doing the same as --rw but
overwrites any existing cache data. This can be handy for
debugging and testing purposes.
* Added "vmdks" output type. Same as "vmdk" but generates a disk
connected to the SCSI bus rather than the IDE bus.
20090710: v0.3.1 released
20090721: * Added function CheckFuseAllowOther to check wether FUSE supports
the "-o allow_other" option. It is supported when
"user_allow_other" is set in /etc/fuse.conf or when running
xmount as root.
* Automatic addition of FUSE's "-o allow_other" option if it is
supported.
* Added special "-o no_allow_other" command line parameter to
disable automatic addition of the above option.
* Reorganisation of FUSE's and xmount's command line options
processing.
* Added LogWarnMessage function to output a warning message.
20090722: * Added function CalculateInputImageHash to calculate an MD5 hash
of the first input image's HASH_AMOUNT bytes of data. This hash is
used as VDI creation UUID and will later be used to match cache
files to input images.
20090724: v0.3.2 released
20090725: v0.4.0 released
* Added AFF input image support.
* Due to various problems with libewf and libaff packages (Mainly
in Debian and Ubuntu), I decided to include them into xmount's
source tree and link them in statically. This has the advantage
that I can use whatever version I want.
20090727: v0.4.1 released
* Added again the ability to compile xmount with shared libs as the
Debian folks don't like the static ones :)
20090812: * Added TXMountConfData.OrigImageSize and
TXMountConfData.VirtImageSize to save the size of the input and
output image in order to avoid regetting it always from disk.
20090814: * Replaced all malloc and realloc occurences with the two macros
XMOUNT_MALLOC and XMOUNT_REALLOC.
20090816: * Replaced where applicable all occurences of str(n)cpy or
alike with their corresponding macros XMOUNT_STRSET, XMOUNT_STRCPY
and XMOUNT_STRNCPY pendants.
20090907: v0.4.2 released
* Fixed a bug in VMDK lock file access. glob_vmdk_lockfile_size
wasn't reset to 0 when the file was deleted.
* Fixed a bug in VMDK descriptor file access. Had to add
glob_vmdk_file_size to track the size of this file as strlen was
a bad idea :).
20100324: v0.4.3 released
* Changed all header structs to prevent different sizes on i386 and
amd64. See xmount.h for more details.
20100810: v0.4.4 released
* Found a bug in InitVirtVdiHeader(). The 64bit values were
addressed incorrectly while filled with rand(). This leads to an
error message when trying to add a VDI file to VirtualBox 3.2.8.
20110210: * Adding subtype and fsname FUSE options in order to display mounted
source in mount command output.
20110211: v0.4.5 released
20111011: * Changes to deal with libewf v2 API (thx to Joachim Metz)
20111109: v0.4.6 released
* Added support for DMG output type (actually a DD with .dmg file
extension). This type is used as default output type when
using xmount under Mac OS X.
20120130: v0.4.7 released
* Made InitVirtImageInfoFile less picky about missing EWF infos.
20120507: * Added support for VHD output image as requested by various people.
* Statically linked libs updated to 20120504 (libewf) and 3.7.0
(afflib).
20120510: v0.5.0 released
* Added stbuf->st_blocks calculation for VHD images in function
GetVirtFileAttr. This makes Windows not think the emulated
file would be a sparse file. Sparse vhd files are not attachable
in Windows.
20130726: v0.6.0 released
* Added libaaff to replace libaff (thx to Guy Voncken).
* Added libdd to replace raw dd input file handling and finally
support split dd files (thx to Guy Voncken).
20140311: * Added libaewf (thx to Guy Voncken).
20140726: * Added support for dynamically loading of input libs. This should
ease adding support for new input image formats in the future.
* Moved input image functions to their corresponding dynamically
loadable libs.
* Prepended "glob_" to all global vars for better identification.
20140731: * Added --offset option as requested by HPM.
* Began massive code cleanup.
20140803: * Added correct return code handling when calling input lib
functions including getting error messages using GetErrorMessage.
* Added input lib specific option parsing.
* Re-implemented InitVirtImageInfoFile() using input lib's
GetInfofileContent() function.
* Further code cleanups.
20140807: * Further code cleanups.
* Renamed GetVirtFileAttr() to FuseGetAttr()
* Renamed CreateVirtDir() to FuseMkDir()
* Renamed CreateVirtDir() to FuseMkNod()
* Renamed OpenVirtFile() to FuseOpen()
* Renamed GetVirtFiles() to FuseReadDir()
* Renamed ReadVirtFile() to FuseRead()
* Renamed RenameVirtFile() to FuseRename()
* Renamed DeleteVirtDir() to FuseRmDir()
* Renamed DeleteVirtFile() to FuseUnlink()
* Renamed WriteVirtFile() to FuseWrite()
* Fixed bug in CalculateInputImageHash() where always HASH_AMOUNT
bytes were hased even if input image is smaller.
* Fixed a newly introduced bug in FuseRead() and GetVirtImageData()
returning -EIO when trying to read behind EOF. The correct return
value is 0.
20140811: * Renamed CheckFuseAllowOther() to CheckFuseSettings() and added a
check to see if user is part of the fuse group.
20140814: * Replaced cuserid() with getpwuid(geteuid()) in CheckFuseSettings()
as it is deprecated on Linux and not available on OSx.
* Only build fuse group checks from CheckFuseSettings() on Linux.
20140820: * Added libxmount_morphing handling.
* Renamed LoadInputLibs() to LoadLibs() and added code to find and
load morphing libs.
* Added FindMorphingLib() function.
20140821: * Changed command line syntax to support specification of multiple
input images of different types.
* Added code in main() to initialize and open multiple input images.
* Added GetMorphedImageSize() and GetMorphedImageData().
20140822: * Removed GetInputImageSize() as it isn't needed anymore.
* Quick test showed morphing using libxmount_morphing_combine seems
to work.
20140825: * Added InitResources() and FreeResources() functions.
20140926: v0.7.0 released
20140930: v0.7.1 released
* Fixed bug with --sizelimit command line option.
20141001: v0.7.2 released
* Fixed bug in FreeResources(). Do not free vdi.p_vdi_block_map as
it is part of vdi.p_vdi_header.
20141113: v0.7.3 released
* Fixed minor bug in ParseCmdLine() which was not checking upper
argc bounds correctly.
20150820: v0.7.4 released
20150901: * Improved the way fsname is built

\f0\fs26 \cf0 xmount allows you to convert on-the-fly between multiple input and output harddisk image formats. xmount creates a virtual file system using FUSE (Filesystem in Userspace) that contains a virtual representation of the input image. \
\
The virtual representation can be in raw DD, Apple's Disk Image format (DMG), VirtualBox's virtual disk file format (VDI), Microsoft's Virtual Hard Disk Image format (VHD) or in VmWare's VMDK file format. \
\
Input images can be raw DD, EWF (Expert Witness Compression Format) or AFF (Advanced Forensic Format) files. \
\
In addition, xmount also supports virtual write access to the output files that is redirected to a cache file. This makes it for example possible to boot acquired harddisk images using QEMU, KVM, VirtualBox, VmWare or alike.}]]>
