There was some discussion on this in comp.sys.atari.st and .ibm.pc 
about this some time ago.  Seems that older versions of the drive 
either won't do 1:1 interleave, or will fail in nasty ways if you 
try it.  The last message I have indicates that returning the 
drive to get it upgraded to ROM version 8 and RAM version 12 will 
make it work properly.  This is in a message from Sept 6 1989...

It might be the controller, if you're using an ST-01 controller.
I seem to recall that they max out at about 700-800 kB/s, which 
is somewhere close to the data rate on a ST-296N.
