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).
