yes. >I thought someone responded with the statement that the controller >controls the mapping out, and doesn't see partitions. yes. Me. The engine doesn't care about the road. Likewise only the tires know the road and don't care what the driver is doing. >The answer then seemed to be yes ... zeroing a partition would cause >the controller to map out any bad sectors.
