Hello Aaron and Michael, This is a machine with a very interesting file corruption case which is most likely malware. I used moonsol's DumpIt to acquire the image from a Win7 64bit SP1 machine with 8 gigs of ram. Here's the output of bin2dmp: bin2dmp - 1.0.20100405 - (Professional Edition - Single User Licence) Convert raw memory dump images into Microsoft crash dump files.

Thank for joining the mailing list. Is the machine you are trying to analyze part of an investigation or a test machine? A physical machine or a virtual machine? Does it have any unusual devices connected to it? If you convert the sample to windbg format using the MoolSols tools, will it load in windows debugger?
