    NOTE:

        THIS PROGRAM CAN DESTROY CUSTOMER DATA.  BE SURE TO HAVE ALL
        VALUABLE DATA BACKED UP AND VERIFIED BEFORE CONTINUING!

    FUNCTIONAL DESCRIPTION:

            This is a Low-Level format utility designed to help you
            maintain GROWN DEFECTS on your WESTERN DIGITAL Intelligent
            Storage Peripheral.

    DRIVE SELECTION:

            The user must select drive 0 or 1 and the model type.

    LOW-LEVEL FORMAT:

            Performs a LOW-LEVEL FORMAT, pre-existing defects are
            mapped out.  ESC will abort back to the main menu.  If
            aborted the user will be warned that previous defects will
            not be updated.

    QUICK-FORMAT/SURFACE ANALYSIS:

            First LOW-LEVEL format is performed then a short SURFACE
            analysis writes and read_verifies the entire surface of
            the disk with two critical patterns.  This function can be
            useful in a production environment.  All pre-existing and
            surface analysis defects will be automatically mapped out.
            ESC will abort back to the main menu.  If FORMAT is aborted
            the user will be warned that previous defects will not be
            updated.

    SURFACE ANALYSIS:

            Ten critical patterns are used to write and read-verify the
            entire surface of the disk.  This function is an in-depth
            check for GROWN defects.  All pre_existing and surface
            analysis defects will be automatically mapped out.  ESC
            will cause an abort back to the main menu, defects are not
            updated.  IF a previous VERIFY updated the grown map,
            SURFACE updates to the map will not occur.  FORMAT or
            UPDATE DEFECTS will clear this condition and allow updates
            to occur.

    VERIFY:

            This function performs a read-verify of the entire disk.
            Any new defects are presented to the user.  Upon exit of
            the defects display the user is asked if the newly found
            defects should be added to the defect list.  Yes will
            append these defects to the GROWN defects map on the drive.
            A subsequent VERIFY will not allow more defects to be marked
            until FORMAT is run.  A subsequent FORMAT or UPDATE DEFECTS
            will then map out these defects along with any previous
            defects.  No will exit without updating the defect list.
            ESC will cause an abort back to the main menu.

    UPDATE DEFECTS:

           This function will update all defects on the drive selected.
           The factory and grown defect lists will be used to update
           defects on the drive.  This will clear a previous VERIFY
           update to the grown defect map and allow SURFACE ANALYSIS
           and VERIFY to update the maps.

    EXIT:

            Any drive in CMOS mother-board setup will be re-established.
            If drive 0 or drive 1 is attached and powered up it will be
            PARKED.  Some systems and drives will not respond after
            this operation.  The user is cautioned to WARM or COLD boot
            the system to GUARANTEE proper operation.

    ERROR LOG DESCRIPTION:

            Drive, Model number and the Function that was executed is
            shown.  Each physical location of a GROWN defect is shown
            once with cylinder, head, sector, status, error, and
            pattern/window information.  The status and error display
            information is from the first error occurance.  The pattern
            and window information are shown from left to right in order
            of occurance.  Each pattern has a letter designation:

             a  d6b5ad6b5a ----------------- Isolated ones WD
             b  c6319c6319                   Isolated ones IBM
             c  cf3cf3cf3cf3 --------------- Isolated ones WD & IBM
             d  492492492492                 HI frequency IBM all ones
             e  0101010101 ----------------- Isolated zero's WD
             f  136b31136bb3                 Mixed all frequency WD
             g  c086043021800c086043021800   WD worst case pattern
             h  5ab6b5ab6b                   Max jitter
             i  3333333333 ----------------- Low frequency
             j  0000000000                   Hi frequency

            The window information has a letter designation:

                E   Early  read
                L   Late   read
                N   Normal read
                W   WRITE  only

            Four pattern/window entries for a designated sector would
            be displayed:

            PATTERN/WINDOW

            aEaLcEcL

            Patterns a and c failed during read-verify with both EARLY
            and LATE window.
