    Abstract: A process, apparatus, and system stores data check information on an electronic storage medium that uses standard sector data field sizes. The check information may include a cyclic redundancy check (CRC), a logical block address (LBA), a longitudinal redundancy check (LRC), state information, a sequence number, or other information to identify data state, misplacement, or corruption. The check information, instead of being appended to the data within the data sector, may be stored in an independent check sector. The check information corresponding to multiple data sectors may also be aggregated and stored in a single check sector. The process or apparatus may be incorporated in a storage system controller, a RAID controller, a software SCSI stack in a computer, an operating system, a storage device driver, or another appropriate application that interfaces with standard and commodity storage system components.

    Abstract translation: 处理,装置和系统将数据检查信息存储在使用标准扇区数据字段大小的电子存储介质上。 检查信息可以包括循环冗余校验(CRC),逻辑块地址(LBA),纵向冗余校验(LRC),状态信息,序列号或用于识别数据状态,错位或损坏的其它信息。 检查信息而不是附加到数据扇区内的数据,可以存储在独立检查扇区中。 对应于多个数据扇区的检查信息也可以被聚合并存储在单个检查扇区中。 该过程或装置可以并入与计算机中的存储系统控制器,RAID控制器,软件SCSI堆栈,操作系统,存储设备驱动器或与标准和商品存储系统组件接口的另一适当应用。
