	The best answer is YOU DON'T!  Definetly don't low-level your
	IDE drive.  Seagate and Conner won't even guarantee they can do
	it at the factory, if you manage to do it yourself you'll just
	end up with a very expensive paper weight.  As far as the interleave,
	it's set for the drive.  Changing it won't increase performance, if
	you change it from 3:1 to 1:1 or 2:1 you'll end up degrading 
	performance by requiring the drive to make an entire pass around
	the cylinder to get to the next sector.  IDE's is what they is and
	they ain't what they ain't.  :-)
