Could it be the case the the sectors you try to read have a length <> 512 ?
I can very well imagine a situation where a PC-based floppy disk controller
cannot handle off-size sectors very well. It will then probably have to do
some error recovery (or whatever), and might miss the start of the next
sector.
Have your tried Octopus ? It has a very powerful dump routine. IIRC you can
also specify the sequence in which the sectors are to be read.
