I'm beginning to understand there are three different words for a given partition type, that is, MBR=Windows=Intel, and one can deduce it is the choice that has been made to run the analysis based on "Your screen is filled with found partitions in CHS (cylinder, head, sector) adresses." This level of guesswork maybe suitable for some people, but for me it just contributes to a feeling of helplessness. Is it such hardship for the software developer, to add "You are running Analysis using partition table type=..."? In case it sparks any comment towards the resolution of my problem, here's the new analysis (the third) that I started x hours ago. It was before going to bed, and I don't remember what partition type it is. The log file is 207GB in size, which is insane.
