Hello all, I have posted this twice because the decompression issue should be moved to vol-dev as Aaron suggested. yesterday Andreas did provide a hiberfil.sys for decompression testing. Thanks a lot again. I have processed it twice with X-Ways-Forensics 15.3 SR3 and Volatility (SVN-release). The good news: Both result files are identical. The bad news: I don’t have any clue why the decompression of my case relevant hiberfil.sys did not properly work with volatility but did with XWF. If anyone other needs a hiberfil.sys decompressed with XWF for testing, do not hesitate to ask me. We have the most recent releases here. (I am back on the 29th of July) I did compare the vol and the XWF-version of my case files but I can’t interpret or explain the differences. What should I look for?
