Abstract
Systems and methods for improving read failure tolerance during read-modify-write operations of data storage systems accommodating a host that uses a logical sector of a size smaller than the physical sector size of the data storage system. In one embodiment, the data storage system can perform sector indirection in response to a read error during a read-modify-write command.
