Now you might know why we introduced "dangerously dedicated mode" ages ago, where there is no true fdisk table, but instead the BSD disk label right away in block #0. (There's a fake fdisk table still, but nobody cares about that.) That way, the disk is portable between whatever "geometry" the BIOS implementation might believe into, since the very first 15 or so blocks are basically always located at the same coordinates, irrespective of the "geometry" imposed. I'm surprised that even different Adaptec controllers now start to experience that geometry mishmash. Previously, this was only a known symptom when migrating a disk from a Symbios Logic based controller to an Adaptec one. -- cheers, J"org .-.-. --... ...-- -.. .
