Western Digital Data LifeGuard Diagnostics - WinDlg (DLGDIAG for Windows)
 

PROGRAM DESCRIPTION:
This MODULE of the Data Lifeguard Tools program searches for and verifies
the status of specific Western Digital drives. By accessing the Data Lifeguard
information stored on the hard drive, the program is able to quickly and
efficiently verify the status of the drive. If any errors are logged or found,
it provides an option to return the drive to a defect-free status through an 
extended test or repair option. WinDlg runs under Win9x/Me/NT/W2K/XP/Vista/Win7 
and offers several options for verifying the defect-free status of your hard 
drive.


QUICK TEST:
The Quick Test is designed to intelligently gather and verify all of the Data
Lifeguard information contained on the drive. The Quick Test can determine with
a high level of confidence that a drive is defect-free in a short amount of time.
For maximum confidence, the Extended Test is recommended. The Quick Test option
may not be available on earlier IDE drives, SCSI drives and external drives.

The Quick Test checks the SMART status and performs SMART QUICK Drive Self-Test 
if the SMART feature is supported by the drive and detected by the program.  
Otherwise, it performs a partial disk scan test - 10% in the OD (Outer Diameter) 
zone and 10% in the ID (Inner Diameter) zone.
 

EXTENDED TEST:
For most computers, the WinDlg Extended Test takes anywhere from 30 minutes to many 
hours to test one drive. Larger drives take longer to test. The performance of the 
computer also affects the test time. If a bad sector is detected under Win9x/Me 
environments, the test may stop responding for a few minutes and then continue. By 
default, this is a non-destructive test. The test is destructive only when the user 
selects the repair function and bad sectors are detected.

The EXTENDED Test scans the entire disk media from LBA #0 to the maximum LBA.  When 
a bad sector is detected, the user is prompted to repair it. If the user chooses to 
repair, the program writes zeros to the bad sector which invokes the drive firmware 
to relocate the bad sector and return the sector to a defect-free state.


WRITE ZEROS:
This option can be used to erase operating systems and file systems. QUICK ERASE 
writes zeroes to the first and last million sectors. FULL ERASE writes zeroes to 
the entire drive and may take hours to complete (depending on the drive size and 
system performance).
 

VIEW TEST RESULT:
This function displays the current test results. Test results are overwritten once 
a new test is started.
 

TO RUN THE PROGRAM:
 
BACK UP DATA:
Before running DLGDIAG, it is recommended that users back up all data for all hard 
drives.  This utility may write to the drive during the re-certification process.  
As with all utilities that write to a drive, it is recommended that you back up your 
data before proceeding. 


TO TEST EACH DRIVE: 
Double click on one of the physical drives in the list to display the test menu. 
Select a test and click the Start button to start the test. At the end of the test, 
a status is displayed. For the EXTENDED TEST, if bad sectors are detected, a repair 
option is provided to fix any correctable errors. However, data stored in the 
bad sectors will be lost, thus this function must be used very cautiously. WD also 
offers a DOS version of DLGDIAG which provides a better repair function. It can be 
downloaded from WD's web site and used to repair certain errors that cannot be 
corrected in the Windows environment. 

The drive's SMART status is queried and displayed when the program starts. The SMART 
status can be PASS, FAIL or Not Available. Click on the SMART status column to view 
detailed SMART disk information.
