<p>A storage module device - data link processor (200d, FIG. 1) manages data transfers between a main host computer (10) and up to eight disk drive units (D0 - D7, FIG. 1). The data link processor (200d) provides a host access unit (FIG. 2.) to the host computer (10) and connects to a Formatter Unit (FIG. 3) which establishes the protocol for accessing a particular sector of a selected disk drive unit and for transferring data to-from a selected disk drive (D0 - D7) via an Interface Circuit Unit (FIG. 4) which insures that only one particular disk drive is selected at a given time. The data link processor (200d) initiates a self-test operation to verify integrity of the host access unit (FIG. 2) and the Formatter Unit (FIG. 3) before data transfer operations can take place.</p> |
