When errors occur on a read operation such as reading diskette files, retries are attempted until the record is recovered or the retry count is reached. If an error exists after the retry count has been reached, the error is considered hard and the record is unrecoverable. As illustrated in the drawing, a read verify operation is performed after the writing of data on diskette to validate the integrity of the data record and the cyclic redundancy check (CRC) bytes.
