You repeated that statement, so I am picking on you :-) Can someone show me how/where exactly modern drives fakes CHS geometry? Let me specifically ask that question about modern (S)ATA drives directly connected to a system (controller). My impression is at least since ATA-7 there is no mentioning of anything CHS-related in the specification. The fact that we keep reading and interpreting some historically defined bytes that are now marked as unused/reserved doesn't mean that those bytes actually mean anything. -- Andriy Gapon
