We agree. I'm glad also. So what actually [cs]fdisk do with the CHS entries in the partition table? Ignore them? Might they convert a given partition start to different CHS units if the partition entry was deleted then recreated at the same cylinder? AFAIS, parted tries hard not to break these [IMHO correctly], right Andrew?
