In a system having multiple hard disks for electronic storage, for example, an electronic reprographic system having three hard disks for software and image storage, it is desirable to have the disks and associated reaawrite control logic maintain the integrity of the stored data at all times. Unfortunately, systems of this type occasionally, for whatever reasons, are suspected of corrupting data stored therein. For this reason, it is necessary to provide a diagnostic test, capable of running on such a system, to verify the ability to write and read data from each of the disks.
