SUMMARY

Dumpchk is a command-line utility you can use to verify that a memory dump file has been created correctly. Dumpchk does not require access to symbols.

You can download debugging tools for Windows products from the following Microsoft Web site:
http://www.microsoft.com/whdc/DevTools/Debugging/default.mspx
Dumpchk is located in the following locations:
  • Windows NT 4.0 CD-ROM:
    Support\Debug\<Platform>\Dumpchk.exe
  • Windows 2000 CD-ROM: Install the Support Tools by running Setup.exe from the Support\Tools folder on the CD-ROM. By default, Dumpchk.exe is installed to the Program Files\Support Tools folder.

MORE INFORMATION

Dumpchk has the following command-line switches:
   DUMPCHK [options] <CrashDumpFile>

     -? Display the command syntax.

     -p Prints the header only (with no validation).

     -v Specifies verbose mode.

     -q Performs a quick test. Not available in the Windows 2000.
				
Additional switches that are only available in Windows 2000 Dumpchk.exe version:
    -c Do dump validation.

    -x Extra file validation. Takes several minutes.

    -e Do dump exam.

    -y <Path> Set the symbol search path for dump exam. 
       If the symbol search path is empty, the CD-ROM
       is used for symbols.

    -b <Path> Set the image search path for dump exam.
       If the symbol search path is empty, <SystemRoot>\system32
       is used for symbols.

    -k <File> Set the name of the kernel to File.

    -h <File> Set the name of the hal to File.
				
Dumpchk displays some basic information from the memory dump file, then verifies all the virtual and physical addresses in the file. If any errors are found in the memory dump file, Dumpchk reports them. The following is an example of the output of a Dumpchk command:
   Filename . . . . . . .memory.dmp

If there is an error during any portion of the output displayed above, the dump file is corrupted and analysis cannot be performed.

In this example, the most important information (from a debugging standpoint) is the following:
   MajorVersion . . . . .free system
   MinorVersion . . . . .1057
   MachineImageType . . .i386
   NumberProcessors . . .1
   BugCheckCode . . . . .0xc000021a
   BugCheckParameter1 . .0xe131d948
   BugCheckParameter2 . .0x00000000
   BugCheckParameter3 . .0x00000000
   BugCheckParameter4 . .0x00000000
				
This information can be used to determine what Kernel STOP Error occurred and, to a certain extent, what version of Windows was in use.
