  • receiving, by a controller, an indication that a memory management table loaded to a random-access storage device and associated with a non-volatile storage device is in a corrupted state;

    retrieving one or more error recovery parameters of a memory unit stored in metadata of a physical block of a plurality of physical blocks of the non-volatile storage device;

    examining the one or more error recovery parameters to determine whether the one or more error recovery parameters indicate the memory unit is fresh or stale;

    updating the memory management table with logical-to-physical translation information of the metadata for the memory unit that is determined to be fresh; and

    writing the updated memory management table to the non-volatile storage device.
