日本电子维修技术 希捷11代12代硬盘固件门F3修复指令详解

1) ASCII Diagnostic Mode
    This mode is enabled by Control-Z. In this mode, the drive will respond to all ASCII commands described in this document. It will not respond to ESLIP encoded packets received over the serial port interface. In this mode, the native interface (SATA, SCSI, SAS, FC) is not alive.  

        - Entering a Control-Z character from YASPP (or any similar host serial port program) while the drive serial port is in ESLIP mode or ASCII Online mode will switch the serial port to ASCII Diagnostic mode.  

        - Entering a Control-R character while the drive serial port is in ASCII Diagnostic mode will switch the serial port to ASCII Online mode. In this mode, the native interface (SATA, SCSI, SAS, FC) is alive.

        - Entering a Control-T character while the drive serial port is in ASCII Diagnostic mode will switch the serial port to ESLIP mode.

(2) Initialize Defect List (Level T 'i')

  Description:This command initializes the Defect List to contain no defects.

  Quick Help:

    "InitDefectList, i[DefectListSelect],[SaveListOpt],[ValidKey]";

   Input Parameters:  

    0 - List Selection.      

        This parameter is a bit significant value that specifies which defect lists are to be initialized.  Setting a bit indicates that the corresponding defect list is to be initialized.      

             bits 31-3:  Reserved for possible use for additional lists

             bit 2:      User Alt List

             bit 1:      Reserved (ignored)

             bit 0:      User Slip List

             Type:    Unsigned 32-bit value

             Range:   1 or 4 or 5

             Default: None

    1 - Action      

       0 - defects will be cleared in the current, volatile, copy of the defect            list(s) in RAM , but lists won't be written to disk, modification is TEMPORARY .

       1 - modified ( cleared ) versions of defect lists will be written

           to disk, defects are PERMANENTLY cleared.

       2 - the defect list will be read from non-volatile memory, overwriting

           any changes in volatile memory.

           Type:    Unsigned 32-bit value

           Range:   0 to 2

           Default: 0

    2 - Valid Command Key.      

        This parameter must be equal to 22 Hex.  If this parameter is not equal to 22 Hex, the command will not be executed.      

          Type:    Unsigned 8-bit value      

          Range:   0x22      

          Default: None     

  Output Data:  

    If an error occurred, the following information will be displayed.

          "DiagError aaaaaaaa " where aaaaaaaa is the Diagnostic Error Code  

   Examples:  

    Example #1:

    To initialize the slip list to zeros:     

      T> i1,,22  

    Example #2:

    To initialize the alt list to zeroes and save the zeroed list to disk:  

      T> i4,1,22  

    Example #3:

    To reread the alt list from disk:  

      T> i4,2,22  

  (3). SMART Control (Level 1 'N')

          0x05: DUMP_SMART_ATTRIBUTES - retrieves SMART's attributes.

          0x06: DUMP_SMART_THRESHOLDS - retrieves SMART's thresholds.

          0x08: DUMP_CE_LOG - retrieves the critical event log.

          0x23: CLEAR_PERSISTENT_INFO - clears persistent information.

          0xFF: NO_COMMAND      

          Type:    Unsigned 8-bit value      

          Range:   0x00 to 0x23      

          Default: None      

    1 - Variable Parameter      

        Multi-purpose parameter. Used in command 01 to initialize Fast Flush and Media cache. Used in command 03 as the number of the attribute to change.      

          Type:    Unsigned 16-bit value

          Range:   0 to 0xFFFF

          Default: None      

    2 - Boolean Bit Value.   

        Used in command 03 to set/clear the boolean value for the bit.      

          Type:    Boolean value

          Range:   0 to 0x1      

          Default: None  

  Output Data:  

    If an error occurred, the following information will be displayed.      

          "DiagError aaaaaaaa " where aaaaaaaa is the Diagnostic Error Code      

     N1 - initialize Smart data

     N5 - display attribute values

     N6 - display threshold values

     (4). Format Partition (Level T 'm')

  Description: This command formats the specified partition.

   Quick Help:  

  "FormatPartition, m[Partition],[FormatOpts],[DefectListOpts],[MaxWrRetryCnt],[MaxRdRetryCnt],[MaxEccTLevel],[MaxCertifyTrkRewrites],[ValidKey],[DataPattern]";  

  Input Parameters:  

    0 - Partition Number.      

        This parameter specifies the media partition to be formatted.      

             0 = User Partition

             1 = System Partition     

          Type:    Unsigned 8-bit value     

          Range:   0 or 1     

          Default: 0

        1 - Format Options.      

        This parameter is a bit significant value that selects the following options:

            Bits 31-6: not used      

            Bit 5: Enable SeaCOS XF Space Format.     

                   This bit is only valid when the User Partition is selected.  If this bit is equal to 1, the the Format Partition command will only format                    SeaCOS Extended File (XF) space.

            NOTE: This feature can be enabled or disabled at compile-time.  Use the quick help to determine whether your code supports this feature.      

            Bit 4: Enable Zone Re-format Skipping.

                   If this bit is equal to 1, then the Format Partition command will enable the zone re-format skipping mode during the format operation.                    With this mode enabled, the format operation will not re-format                   a zone if grown defects were found in the zone.

                   NOTE: This feature can be enabled or disabled at compile-time.  Use the quick help to determine whether your code supports this feature.  

            Bit 3: Enable Event-based Format Logging.  

                  If this bit is equal to 1, then the Format Partition command will display information about error events that occur during the format                    operation.  This information will be displayed as interim status as                    these events occur.

                   NOTE: This feature can be enabled or disabled at compile-time.  Use the quick help to determine whether your code supports this feature.      

            Bit 2: Disable User Partition Certify.

                   This bit is only valid when the User Partition is selected.  If this bit is equal to 1, media certification and defect deallocation will                    be disabled.

            Bit 1: Disable User Partition Format.      

                   This bit is only valid when the User Partition is selected.  If this bit is equal to 1, the User Partition sectors will not be written                    with a constant data pattern.      

            Bit 0: Corrupt User Partition Primary Defects.      

                   This bit is only valid when the User Partition is selected.  If this bit is equal to 1, the primary defective sectors will be corrupted.      

          Type:    Unsigned 32-bit value      

          Range:   0 or 0xFFFFFFFF      

          Default: 0 (Enable User partition Certify,

                      Enable User Partition Format,

                      Don't Corrupt Primary Defects)
