Abstract
An array disc memory apparatus connected to a computer and including disc drive modules for storing divided data. The apparatus provides means for confirming whether identification information read from disc drive modules installed in the equipment coincides with reference identification information read from disc drive modules previously installed in the same position every time the disc drive modules are replaced, increased or decreased, and produces either an alarm signal for stopping the computer sending a data write or read command to the array disc memory equipment or a data path instruction for allowing the divided data to be correctly written or read from the disc drive modules when the identification information does not coincide with the reference identification information.
