Thank you for this explicit encouragement. Knowing that you have heard me without speaking tells me my guesses at least appear sane at first glance. I deeply enjoy the learning, I only hesitate over how much of it to broadcast here. I can switch over to a less prominent blog whenever you like. I think next: I will begin again in 2.6.6-bk8 without the auto sense patch of this thread. Rather than branching on when auto sense is appropriate, I will try the simpler, intermediate step, of rudely adding an unsolicited auto sense to every command, by way of adding fragments of your auto sense patch. That should let me see which fragment (or combination of fragments) first causes trouble. I happen to know I have a robust PATA device: I believe often enough it will survive such abuses as unsolicited sense, reading x1F0 Data while BSY:DRQ != 0:1, etc. Pat LaVarre
