README - WDDIAG


PROGRAM SUMMARY:

    This program searches for and verifies the status of specific 
    Western Digital drives. Also, if errors are found, it provides
    an option to return the drive to defect-free status.
    

PROGRAM RUNNING TIME:

   For most computers WDDIAG takes 4-15 minutes to test one drive.  
   Larger drives take longer to test. The performance of the computer
   also affects the test time.

   If the drive has defects that WDDIAG can repair, then the repair
   and rescan of the drive takes an additional 4-16 minutes.


TO RUN THE PROGRAM:

    BACK UP DATA: Before running the program, it is recommended that
    users back up all data for all hard drives. The WDDIAG test 
    does not overwrite any data on the drives and if used properly 
    should not result in data loss, but the regular backing up of 
    data is always recommended. 

    STORE THE PROGRAM ON FLOPPY DRIVE: The program must be run
    from a floppy drive, so copy the file WDDIAG.EXE to a formatted 
    bootable floppy diskette in A:.  Running this program from the 
    target hard drive while using certain operating systems can 
    result in data loss and an inaccurate scan of the target drive.

    START THE PROGRAM: To start the program, type WDDIAG at the
    A:\ DOS prompt.
    
    TEST EACH DRIVE: 
    Pick the 'Select Drive' option to see a list of all drives 
    installed and the current status of each drive.

    For each drive that shows a status of 'TEST THE DRIVE', select
    the drive by using the up/down arrows until the desired drive
    is highlighted, then from the main menu pick the 'Test Drive'
    option to test the drive.

    The 'Test Drive' option will take several minutes to complete
    depending on the size of the drive and the speed of the computer).
    At the end of the test a status is displayed. Also, the status for
    all drives is always available by choosing the 'Select Drive' option
    from the main menu.
      
    If errors are detected during the 'Test Drive' option, the user
    will be given the option to attempt to repair the errors.

    Use the 'Select Drive' and 'Test Drive' and 'Repair Drive' options 
    to select and test and repair each drive until the status for 
    each drive is one of the following:

         "DRIVE HAS NO ERRORS" - The drive has passed the test and is
                                 error-free.

         "CONTACT WD TECH SUPPORT" - The drive has not passed the test
                                     and the user should contact WD 
                                     Technical Support for additional
                                     information.

         "NON-WD DRIVE DETECTED" - The drive is not a WD drive and no
                                   additional testing is supported.

      Pick QUIT from the main menu to quit the test. At this point 
      a message will inform you that the system should be reset to 
      reinitialize the BIOS and hard drive(s). Hit CTL-ALT-DEL or
      cycle power to restart the system.

      When rebooting, remove the floppy diskette so the system boots
      to C: instead of A:.


REPAIRING A DRIVE:

In some cases the status of a drive will be set to 'Repair The Drive'
following the Test Drive option. In this case the user should run the 
Repair Drive option and rescan the drive to verify that it has been 
returned to defect-free status.

When repairing a drive, user data is not lost when sectors are relocated,
but user data is lost when tracks are relocated. 

When relocating a sector, the data is read from the sector if possible and
written to the new sector. However, in most cases if a sector needs to
be relocated the data is not recoverable from the damaged sector and the
new sector is filled with zeros. No additional data is lost during the
relocation since the data was already unreadable.

A warning message is displayed whenever tracks will be relocated. Tracks 
should only be relocated on a drive if the data for the drive has been 
backed up to another storage device since all data for the drive will 
have to be restored by the user after finishing with WDDIAG.

Early-model WD drives are not repairable:
        AC140, AC160, AC280, AC2120, AC2170, AC2200


TO CONTACT WD:

      In some cases the user may be requested to contact Western 
      Digital Technical Support. You may contact Western Digital
      Technical Support at (949) 932-4900 or (800) 275-4932 in the
      U.S., or (31) 20.446.7651 in Europe, or consult your drive 
      manual for further information. Alternately, you may contact 
      the OEM or its warranty service provider who can support your 
      needs.


MAIN MENU OPTIONS:

    The following menu options are available:

    Select Drive            select drive and view status for all drives
    Test Drive              test the selected drive
    View Test Results       display results for last drive tested
    Print Test Results      print results for last drive tested
    Log File Open/Close     store results for all drives tested - WDDIAG.LOG
    Repair Drive            repair errors found during the Test Drive option
    Write Zeros To Drive    write zeros to the drive
    Enter & Print RMA Info  enter and print RMA when returning a drive to WD
    Quit


LOG FILE:

    The test results for all drives tested during the last run of
    WDDIAG are stored in the file WDDIAG.LOG.

    By default, the log file is created. It can be disabled using
    a command line option. It is also disabled if the test is run 
    from a write-protected floppy. And it is disabled if the log 
    file is being stored on a hard drive and the hard drive under 
    test required a Set Parameters command (this avoids corrupting 
    the data on the hard drive since the drive being tested may be 
    the drive containing the log file, and the test drive may no 
    longer be set to the parameters assigned by the BIOS).


COPY OF LOG FILE IN MEMORY (SHOWN WITH MAIN MENU 'VIEW TEST RESULTS' OPTION):

    The copy of the log file that is shown on the screen only 
    contains results from the last test. Every time a new test 
    is selected from the main menu, the log file in memory is 
    cleared. The log file on the disk captures the results from 
    all the tests as they are run.


LOG FILE OF ALL TESTS:

    The file HISTORY.LOG contains all of the previous WDDIAG.LOG
    files.  The file HISTORY.LOG should be deleted periodically if
    WDDIAG is being run repeatedly to conserve disk space.


COMMA FILE:

    The test results are stored in comma file WDDIAG.CS1. A new 
    record is appended to the file each time a test is run. The 
    comma file is disabled whenever the log file is disabled. A 
    record has the following fields:
    
        A16     serial number
        A14     model 
        N       model id byte
        A16     firmware string
        A12     dcm string (will be 'UNKNOWN' if unknown)
        A14     build date (format MM-DD-YYYY) (01-01-1980 if unknown)
        N       final error code
        N       test complete  (0 = incomplete, 1 = complete)
        A10     date  (format MM/DD/YY)
        A10     time  (format HH:MM:SS)
                     
        
COMMAND LINE OPTIONS:

    The following command line options are supported:

       -A      Disables error code for SMART failures (ignores SMART)
               This option can be used to allow scanning of drives 
               when SMART is failing before the scan.
               
       -C      Disables output to comma file WDDIAG.CS1.

       -DX     Selects drive X (used with the -V option)

                 X       Baseport       Drive

                 0       1F0            0
                 1       1F0            1
                 2       170            0
                 3       170            1
                 4       1E8            0
                 5       1E8            1
                 6       168            0
                 7       168            1

       -H      Disables appending of log file to the file HISTORY.LOG.

       -K      Keeps the log file open even after a Set Parameters 
               has been issued. This option should only be used if
               the log file is being stored on a drive other than
               the test drive.

       -L      Disables output to log file. This option takes priority
               over the -K option.

       -R      Scan/repair/rescan the drive without showing the menu. The
               drive to be tested is specified with the -D option.
               
       -S      Skip the rebooting of the system after a Set Parameters
               has been issued. This option should only be used if
               the drive being tested is not one of the system drives.
               See additional info in the section titled Additional 
               Program Info.
                 
       -V      Read Verify Entire Drive without showing the menu. The
               drive to be tested is specified with the -D option.

               For example, to run without menus and Read Verify 
               drive 0 at baseport 170, type

                     WDDIAG -V -D2


ADDITIONAL PROGRAM INFO:

    When the program exits to DOS there is a message explaining
    that the system needs to be reset. The Set Parameters 
    command may change the setup of the drive and cause the system 
    BIOS to access the drive incorrectly. So the reset is issued to 
    be sure the drive is re-initialized by the BIOS. There is a command 
    line option to disable the reset. This option can be specified if 
    the user is sure that the drive being tested by WDDIAG is not one 
    of the system drives accessed by the BIOS.
