Zusammenfassung:	DATA INTEGRITY CHECKING WITH FAULT TOLERANCE Fault tolerant apparatus for generating error correcting code and, simultaneous therewith, checking the correctness of the generation, for blocks of data with which the error correcting code is associated and transmitted to a storage medium. The apparatus includes a pair of programmable control devices configured to selectively operate in one of two modes: A first mode in which data being transferred to the storage medium is monitored for generation of an error correcting code to be associated and stored with each data block, and a second mode in which the data being transferred is monitored for detecting errors that may be contained in the data. During data transmissions to the storage device, one of the control devices operates in the first mode, while the other control device operates in the second mode to check operation of the first device. When data is retrieved from the storage device, both control devices operate in the second mode to check the correctness of the data being transferred, and the operability of each other.
