Summary:Various embodiments for data error recovery in a tape storage system, by a processor device, are provided. In one embodiment, a method comprises, in a tape storage system using an iterative hardware decoder and an iterative microcode decoder, modifying erasure control configuration settings upon rereading a buffered dataset having passed through at least one microcode-initiated iterative decode cycle.
