Abstract
A sequence code verification system can be designed to include a data reader, a validity engine, and an error notifier. The data reader can read sequence codes from consecutive logical blocks. The validity engine can 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 can notify a user of an error for each invalidated write operation batch. The system can validate 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. The sequence code can remain constant for each write operation batch and the sequence code can be incremented for each new write operation batch.
