The MD21 controller needs 4 cylinders (I don't remember the reason). But the cyl parameters should be: ncyl + acyl + 4 = pcyl I was told from my distributor that the total number of physical cylinders was 1931, rather than the 1949 listed here, probably because he has a 1.5GB version rather than my 1.2GB drive (the model number on my drive is 94601-12G). Call your dealer and ask for some of the parameters, such has the number of physical cylinders, the number of heads, the number of bytes per track, the rpm of the drive. Go figure from there.
