    This command spins the drive down.

  Input Parameters:
    None

  Output Data:


    If an error occurred, the following information will be displayed.
    
          "DiagError aaaaaaaa"
    
       where
    
          aaaaaaaa is the Diagnostic Error Code
    
    
    In addition, one of the following strings will be output to indicate the current Spin
    State.
    
          "Spin Down Complete"                      or
          "Spin Up held prior to Unlatch"           or
          "Spin Up held prior to Demod Sync"        or
          "Spin Up held prior to Track Follow"      or
          "Spin Up Complete"                        or
          "Spin Error"                              or
          "Invalid Spin State"
    
    The elapsed time for the spin operation will be displayed as follows.

    
       "Elapsed Time a mins b secs"  or
       "Elapsed Time b.c secs"       or
       "Elapsed Time c.d msecs"
    
    where
    
       a is minutes
       b is seconds
       c is milliseconds
       d is microseconds
    
    If a spin error occurred, the following additional information will be displayed.
    
          "R/W Status c R/W Error dddddddd"
    
       where
    
          c is the status returned by the R/W subsystem
    
                0 = R/W request completed successfully with error recovery
                1 = R/W request completed successfully (no error recovery performed)
                2 = R/W request failed
    
          dddddddd is the error code returned by the R/W subsystem
    
    If a spin error occurred and the Verbose Formatted ASCII Data Output Mode is selected,
    the Verbose Mode option bits will enable the following data to be output when set.
    
       Bit 0-6:    NA
       Bit 7:      Enable the Servo Event Log to be displayed
       Bits 31-8:  NA
    
    If Bit 7 is set, the contents of the Servo Event Log will be displayed as follows.
    

    The Servo Event Log Information will be displayed as follows.
    
          "Servo Event Log"
          "cccc cccc cccc ... cccc" (repeated until all entries have been displayed)
    
       where
    
          cccc is a 16-bit Servo Event Log entry
