Due to current sophisticated disk storage devices and interfaces, the underlying disk system performs many error detection steps, bad sector re-mappings, and retry attempts. There is little chance that a deterministic set of steps can be performed to work around the failure if a physical error propagates to the Swarm software level. Additionally, there is no guarantee the extent of the error can be isolated or the continued use of a failing device allows the node to continue operating normally with its peripheral storage devices.
