Zusammenfassung:This disclosure relates to validating data written to logical blocks on a storage subsystem adapted so that during write operations an additional sequence code is written to each logical block of data, where the sequence code remains constant for each write operation batch and where the sequence code is incremented for each new write operation batch. A sequence code verification system may comprise a data reader, a validity engine, and an error notifier. The data reader may read sequence codes from consecutive logical blocks. The validity engine may invalidate write operations in response to checking data validity by applying comparison operations to sequence codes and block offsets of batch write operations. The error notifier may notify a user of an error for each invalidated write operation batch.
