We have had different results with different drives and controllers, most of the time the M24 works fine with interleave 4 (where i/l 3 results in 17 revolutions to read a single track), but sometimes we have to use interleave 7 (resulting in 5 revolutions to read a track, when i/l 3, 4, 5 or 6 doesn't do any good for that specific machine).(Erasmus Universiteit Rotterdam, ApparatuurBeheer Fac.Econ.Wet.)
