It's technically accurate becaues a disk with 65520 cylinder is still a 3390-9. Not that anyone calls them those... Bigger than those will be called 3390-A and can go to something like 262,000 cylinders.

Maybe the table in the documentation should say "3390-9 or bigger" .. -- Bruce Hayden Linux on System z Advanced Technical Support IBM, Endicott, NY
