The failure is in the IDE core layer. In a nutshell, we've never *actually* supported PIO r/w for nsectors > 1, I just started testing it as a spec compliance item (and because it was easy to just swap out DMA with PIO commands in my test framework.) It looks like my tests passing on LE are just an unfortunate coincidence. I'll prepare some patches tomorrow. Thanks, --js
