Abstract: Systems and methods are disclosed, including maintaining an error recovery data structure for a set of codewords (CWs) in a storage system and performing error recovery for the set of CWs using a set of error handing (EH) steps until each CW of the set of CWs are indicated as correctable in the error recovery data structure. The error recovery can include determining if each CW of the set of CWs is correctable by an EH step, storing indications of CWs determined correctable by the EH step in the error recovery data structure, determining if one or more CW in the set of CWs are not indicated as correctable in the error recovery data structure, and, in response to determining that one or more CW in the set of CWs are not indicated as correctable in the error recovery data structure, incrementing the specific EH step.
