You could use ICKDSF to format e.g. a 101 cylinder "work" MDISK, then use DDR to copy that work Mdisk from *cyl 1 to 101 reorder to 100* onto the extended Linux MDISK. Notes: - We do not copy cylinder 0 of that work mdisk: cylinder 0 contains not all 4K records - Beware: destroying the target Linux MDISK is very easy: in your example you tell to format cyl 99 to 199. you would have destroyed the last cylinder of the "old" linux disk. - If you extend by more than 100 cylinders, the "work" mdisk doesn't need to be bigger, you can repeat the DDR and change the reorder every iteration.
