Abstract
Data transferred from a host system to magnetic tape storage are divided into blocks that are converted, written to storage and read. An error checker determines whether errors in each block exceed a predetermined number. The result is output with corresponding header identifying information. Information, including header identifying information corresponding to each block written to storage, is stored in a history store. Header identifying information output by the error checker is compared with the header identifying information to identify the data block relating to the error checking output. The marked data block associated with the matching header identifying information is indicated as being good or bad according to the error checker. Selected parts of the header identifying information are masked to compare only the remaining portion of the information with the corresponding history store information.
