Are you sure of that, do you have some tech doc on this, datasheet for a 
particular model ?

This would explain a lot of things, but I think I read on the contrary 
that many drives (not 3.5'') had internal index, while the 3.5'' relied 
on the one present on the floppy (and as far as I understand their code, 
the IPF library that emulates the WD1772 also assumes index on the floppy)
