That's not how it works.. the 'physical' stop is always used to reference cylinder zero, whether it's dos or x-copy. Now, you could have a borderline alignment problem that will show itself when switching the stepping direction, or a mechanical problem that causes misalignment in the same situation. Under those circumstances, ROC is right in the sense that reading the whole disk from cylinder zero to 79 might work, while random access won't.
