ImDisk Virtual Disk Driver

Current version 2.1.1 built 30 October 2021 packaged 16 November 2022

ImDisk is a virtual disk driver for Windows
NT/2000/XP/Vista/7/8/8.1/10 and Windows Server 2003/2003 R2/2008/2008 R2/2012/2012 R2, 32 and 64 bit editions. It can create virtual hard disk, floppy
or CD/DVD drives using image files or system memory. The install
package installs a console-mode control program called
imdisk.exe and a Control Panel
applet
. After install is
finished, type
imdisk
without parameters for syntax help or double click the
ImDisk icon in the Control
Panel. It also adds a menu item in Windows Explorer so that you can
right-click on a file to mount it as a virtual disk drive. Users of
mdconfig in FreeBSD will
probably be familiar with the command line syntax of
imdisk.exe. The driver, service
and control program can be uninstalled using the Add/Remove programs
applet in the Control Panel. No reboot is required for installing or
uninstalling.

An additional driver, awealloc, in this install package supports memory
allocation beyond 4 GB limit on 32 bit Windows through address window extension,
AWE.

The
ImDisk driver supports forwarding I/O requests to third-party image file format
handlers or to services on other
computers on the network. This makes it possible to boot a machine
with NTFS partitions with a Live-CD and use the included 
devio tool to let
ImDisk on another computer
running Windows on the network mount the NTFS partition on the
machine with a faulty NTFS partition. This way you can recover information and
even run chkdsk on drives on machines where Windows does not boot. There are also instructions about how to use
devio under Windows on
Claus Valca’s blog.

About the install package

The install package is created using 7-zip sfx stubs and includes an
.inf install script. No reboot is required after installing or
uninstalling. The install package works on Windows NT 4.0, Windows 2000, Windows XP,
Windows Server 2003, Windows Vista, Windows Server 2008, Windows 7, Windows 8 and Windows 8.1, on both 32-bit and 64-bit
versions.

Compatibility

ImDisk Virtual Disk Driver is designed to be a small, simple and yet powerful virtual disk driver. It runs on very old versions of Windows NT as well as modern Windows versions. However, because of this compatibility design and because it emulates disk volumes rather than complete disks, it is not always compatible with all applications and drivers. For instance, you cannot manage things like mount points, drive letters and similar for ImDisk drives using mountvol command line tool or in Disk Management in Windows. As another example, you cannot create or access shadow copies on ImDisk drives. So, applications that use similar Windows features as Disk Management dialog to enumerate disks and disk volumes to find disk properties like sector sizes and similar, might possibly not work as expected with ImDisk drives.

Arsenal Image Mounter — If you need full disk emulation support

If you need full disk emulation, including integration with Disk Management, Volume Shadow Copy Services, mountvol and diskpart command line tools as well as better compatibility with applications, we provide another open source virtual disk project, called Arsenal Image Mounter. It is published together with Arsenal Recon and is available for download here. It is available for non-commercial use under AGPL license. Commercial license options available, please contact Arsenal Recon for more information. Source code, command line tools, driver setup packages and similar for Arsenal Image Mounter are available on GitHub. The directory structure is desribed in
this document.

ImDisk Toolkit

The ImDisk Toolkit is a complete package that adds a more modern and intuitive user interface to ImDisk. ImDisk Toolkit offers features like automated creation of memory disks at system startup and mounting many different image file formats. It is developed and maintained by «v77». It is available for
download here.

CPU architecture compatibility

Almost all of the source code is identical for all supported CPU architectures. Currently supported architectures are x86, ia64, x64, arm32 and arm64. All
features and most limitations are the same in the 64-bit and 32-bit
versions. One difference however, is that the 64-bit versions
do not have any practical size limits for virtual disks backed by memory.

Driver files are digitally
signed with a certificate trusted by Microsoft.

This means that ImDisk works on Windows Vista and later
without running in testsigning mode.

Special note for Windows NT 3.51

The .inf file used in the install process is not compatible with
Windows NT 3.51. To install on NT 3.51 you can extract the files in
the packages using 7-zip and then manually create the driver keys in
the registry or using a SCM control tool like
sc.exe in the Windows NT
Resource Kit. On later versions of Windows you just run the package
and it will install everything automatically.

Source code

Source code for all of ImDisk Virtual Disk Driver,
including the devio server-side tool, API libraries etc is available as a Github repository. Different parts of the source tree are built in different environments:

• The Windows drivers, command line tool and Control Panel applet parts of the source code are built with WDK 7.1.0. There is a Makefile in the source tree root that builds imdisk.sys, awealloc.sys, imdisk.cpl, imdisk.exe and imdsksvc.exe when ran with nmake in WDK 7.1.0 command prompts.
• The devio server side tool used with ImDisk clients in proxy mode, can be built with most *nix C++ compilers like gcc and similar. It can also be built in most Visual Studio/C++ command prompts. In all cases the devio binary you get supports listening for a tcp/ip connection and serving either a raw image file or a Microsoft vhd image file and parsing MBR partition tables to find offsets and sizes. When built with Visual Studio/C++ compilers, you will get a devio.exe that also supports listening for shared memory connections, the —dll switch to load custom dlls for accessing custom image file formats and features for auto-finding sizes of a physical devices.
• The .NET library located in ImDiskNet subdirectory can be built using Visual Studio 2017 or higher or any recent version of .NET SDK.
• There is also a Visual Studio solution with some project files for the driver, Control Panel applet, imdisk.exe and devio.exe. It is particularly useful to build for architectures not supported by the old WDK 7.1.0 environment, such as arm and arm64.

API

API functions are available for C/C++, COM and .NET clients. If you want to call functions for
creating/removing/querying virtual disks from your own program you
can #include the file inc\imdisk.h in your C/C++ source files and
link the cpl\i386\imdisk.lib library.
Read inc\imdisk.h in source archive for documentation about C/C++ usage. If you would like information
about how to write compatible server-end software in C/C++ you can take a
look at the I/O packet structures in inc\imdproxy.h.

A class library DLL for COM and .NET developers is available as separate wrapper DLLs,
published at NuGet.
LTRData.ImDiskNet and
LTRData.DevioNet, it can be used with .NET Framework 2.0 or later.

Look here
for on-line documentation about .NET API. There are also, as usual, xml
files with method/parameter descriptions available to each assembly file.

There is also a .NET application, DiscUtilsDevio, that combines image file format support in DiscUtils libraries with ImDisk.

License

I have received some e-mails with questions whether or not it is
okay to include this driver in a commercial product. The answer is
yes, just like all other tools I publish here. However, note that a few lines of code are under the GNU GPL license. More specifically, the driver code related to floppy
emulation. Some of the driver code is also ported to Windows NT from
the FreeBSD ‘md’ driver.

This means that if you modify the code and/or include it in and/or redistribute it along with your own product, all of the modified/integrated/redistributed product that you distribute needs to be redistributed under GPL, including source code. If you wish to avoid GPL requirements, such as the need to redistribute source code, you would therefore need to remove all floppy emulation related code from the driver. I
will be happy to do such modifications for you to make the code comply with your license requirements. Just send me an e-mail!

Zero and Random device driver — updated
16 November 2022

The Zero and Random device driver creates two device objects,
\Device\Zero and
\Device\Random and a symbolic
link to each of these under
\DosDevices
so that they are reachable from Win32 applications using the syntax
\\.\zero and
\\.\random. The devices work
like /dev/zero and /dev/random in *nix like environments.
Zero produces zero characters
and
Random produces random
characters in the read buffers. When written to both of the device
objects act like a
Null
device, that is just accepting and ignoring the data in the write
buffer. The drivers can e.g. be used with the classic
dd tool or with my
rawcopy tool to fill files,
devices etc with zero or random characters, e.g. to wipe out the
contents of a hard drive.

Beginning with version 1.1.0.3 different versions are installed on different versions of Windows. On Vista and later, random numbers are generated by system cryptographic random number generator. On earlier versions random numbers are generated by
RtlRandom or
RtlRandomEx API functions with a time based seed.

The install package installs the driver and loads it into the kernel
and setup for automatic load when Windows starts up. The driver can
be uninstalled using Add/Remove programs applet in the Control
Panel.

• Download the install package
  — 172,9 KB. Works on both 32-bit and 64-bit versions of Windows. Security Notice: Always download setup packages to a new empty directory. To run a setup package from a directory with other unrelated files could be dangerous!

About the install package

The install package is created using 7-zip sfx stubs and includes an
.inf install script. No reboot is required after installing or
uninstalling. The install package works on Windows NT 3.51/NT
4.0/2000/XP/Server 2003/Vista/Server 2008, both 32-bit and 64-bit
versions.

Drivers are now digitally signed with a certificate
trusted by Microsoft.

This means that this driver now works on Windows Vista and later even without running it testsigning mode.

Special note for Windows NT 3.51

The .inf file used in the install process is not compatible with
Windows NT 3.51. To install on NT 3.51 you can extract the files in
the packages using 7-zip and then manually create the driver keys in
the registry or using a SCM control tool like
sc.exe in the Windows NT
Resource Kit. On later versions of Windows you just run the package
and it will install everything automatically.

Source code

Source code for 
this driver is available on
GitHub. The source
code can be built both with legacy Makefile-based WDK build environments and with modern Visual Studio integrated WDK.

Small native Windows command line utilities

Works on Windows NT/95/98/ME/2000/XP/2003 unless the description
says something else. Some of them also run on Windows 3.x with
Win32s but then without displaying anything because Win32s on
Windows 3.x has no console support.

32 bit versions are compiled with Microsoft Visual C++ 7 (2003) compiler. They are not linked with the standard C or C++
libraries that comes with this compiler. Instead, most of them are linked
with a dynamic library I call minwcrt (Minimal Windows C Run-Time
Library) linking them to crtdll.dll instead of msvcrt.dll. This
makes them run in all versions of Win32 without additional dll
files. This is also the reason why the exe files are very small.
Source for this library is available as part of the source archive
mentioned in the top of this document. Some other tools are linked to msvcrt.dll to support formatting 64-bit integers and similar features not available in crtdll.dll. This means that some such tools may require updated MS VC++ runtime dll files on Windows NT 3.51, Windows 95 or Win32s.

64 bit versions are compiled with Microsoft Visual C++ 8 (2005) compiler. They are linked to msvcrt.dll and are compatible with all x86-64 (previously known as AMD64) Windows versions from Windows XP/Server 2003 and onwards.

ARM versions are compiled with Microsoft Visual C++ 12 (2013) compiler. They are linked to msvcr120.dll which is installed on both Windows RT and Windows 10 IoT editions by default.

ARM64 versions are compiled with Microsoft Visual C++ 14.1 (2017) compiler. You need Visual C++ Redistributable package to run these versions. It is available
here.

  statistics to some company. After removing such spyware Winsock
  APIs may fail for all applications because there are registry
  references to LSP modules that no longer exists. In Windows XP
  SP2 you can reset LSP chain using the command netsh winsock reset but
  with earlier versions it was almost impossible without
  reinstalling the TCP/IP protocol, as described in KB892350 or
  KB817571.

  Reads and writes files and devices.
  (Cannot read/write disk devices in Windows 95/98/ME or Win32s.)
  For example useful to write a floppy image file on a hard disk
  to a physical floppy in Windows NT. (This can also be done by
  using various Win32 ports of the *nix dd program. But unlike my
  rawcopy, they usually do not unmount/lock physical devices or
  partitions during the read/write which makes them quite
  dangerous to use if anything else is using the device
  meanwhile…) From version 1.2.1 it can also create sparse
  output files with a new -s command line switch. Version 1.3.0 supports
  differential copying.

  Shows total size on disk for files
  or directories. For directories it shows total for all files in that directory, it
  uses backup privileges (if avaiable) to count all files, regardless of whether
  the current user can access them or not. It also shows compressed or sparse size
  rather than virtual size for such files. This tool counts one file only once,
  even if there are several hard links to the same physical file. There is also an
  option to skip reparse points (to let subdirectory search stay within one

  A console backup/archive tool
  for all versions of Windows NT from NT 3.51 up to Windows 10. It uses the same
  backup methods as the ntbackup
  or robocopy programs
  and thus backs up all information and meta data on an NTFS
  volume. The main difference is that strarc is free and open
  source and produces stream archives you can store on tapes,
  disks or anywhere else or it can create the archive stream to
  stdout so that it can be compressed easily using stream
  compression tools like gzip
  or bzip2. The command
  line switches and parameters are quite similar to the *nix tar utility and it can
  easily be used to clone an entire NTFS volume including
  everything, files, directories, their time stamps, attributes
  and security information, compression attribute, alternate data
  streams, junctions, hard links etc. It is now even possible to backup the registry database files of a
  running Windows system. An information file called strarc.txt describing usage
  and including how-to:s and other documentation is included in
  this zip file. The documentation is also available here.

• xcopynt.zip — 14,6 KB (32 bit, compiled 2025-02-13)
  Copies a complete directory tree to
  another location. This tools copies files, directories (even
  empty ones), all attributes, extended attributes, time stamps,
  security information including access permissions (except in
  some cases owner and auditing information). Requires Windows NT
  4.0, Windows 2000, XP or Server 2003. The Windows NT 4.0 version
  of xcopy.exe did not have all this functionality. Note!
  The development of this tool has now come to an end. It has
  several limitations, especially under newer Windows versions (it
  lacks correct support for hard links, compression attribute,
  junction points, etc) and it does not work at all under Windows
  NT version prior to 4.0. I recommend all users of this tool to
  use the new strarc
  instead. If you previously typed xcopynt d:\dir\ you may now use strarc and
  type
  strarc -c | strarc -x
  -d:d:\dir\
  instead.

Small native Windows utilities with
graphical user interface (or with no user interface at all)

Works on all versions of Win32 unless the description says something
else. This includes at moment Windows 95/98/ME/NT/2000/XP/2003 and
Windows 3.x with Win32s installed.

32 bit versions are compiled with Microsoft Visual C++ 7 (2003) compiler. They are not linked with the standard C or C++
libraries that comes with this compiler. Instead, most of them are linked
with a dynamic library I call minwcrt (Minimal Windows C Run-Time
Library) linking them to crtdll.dll instead of msvcrt.dll. This
makes them run in all versions of Win32 without additional dll
files. This is also the reason why the exe files are very small.
Source for this library is available as part of the source archive
mentioned in the top of this document. Some other tools are linked to msvcrt.dll to support formatting 64-bit integers and similar features not available in crtdll.dll. This means that some such tools may require updated MS VC++ runtime dll files on Windows NT 3.51, Windows 95 or Win32s.

64 bit versions are compiled with Microsoft Visual C++ 8 (2005) compiler. They are linked to msvcrt.dll and are compatible with all 64 bit Windows versions from Windows XP/Server 2003 and onwards.

ARM versions are compiled with Microsoft Visual C++ 12 (2013) compiler. They are linked to msvcr120.dll which is installed on both Windows RT and Windows 10 IoT editions by default.

ARM64 versions are compiled with Microsoft Visual C++ 14.1 (2017) compiler. They are linked to vcruntime140.dll and related libraries, which are installed with Windows 10 ARM64 editions by default.
