Getting information out of corrupt minidump files?

[harald.de...@med.ge.com]

Is there a way to get at least some information from a minidump file
that WinDbg can not load because of "The file or directory is corrupted
and unreadable."

The first part of the file is looking not too bad, so I am hopeing that
at least a little bit of information is still there.

This is the output of dumpchk.exe:

C:\Program Files\Debugging Tools for Windows>dumpchk.exe
c:\Mini060205-01.dmp
Loading dump file c:\Mini060205-01.dmp

Microsoft (R) Windows Debugger Version 6.3.0017.0

Loading Dump File [c:\Mini060205-01.dmp]
Could not open dump file [c:\Mini060205-01.dmp], Win32 error 1392
"The file or directory is corrupted and unreadable."
**** DebugClient cannot open DumpFile - error 80070570
DumpFile is corrupt

Alternatively it might also help if there is a "common reason" for
broken dump files - maybe that gives a clue why the system is crashing.

I've had some success in opening a dump in a hex editor and changing the
signature at offset 0. With corrupt dumps you'll typically see PAGEPAGE as
the signature. If you change that to PAGEDUMP Windbg will happily open it
up. I've only done this with full dumps, so I'm not sure how it will work
for you.
