DATA LIFEGUARD DIAGNOSTICS (DLGDIAG)
INTRODUCTION – 1
USER MANUAL
Introduction
The Data Lifeguard diagnostic utility (DLGDIAG) is designed to test WD hard drives
for errors. If DLGDIAG reports errors, you can use the program to attempt to restore
the hard drive to a defect-free status.
DLGDIAG supports WD external and SATA hard drives. It also supports EIDE hard drives
installed on both primary and secondary IDE ports (either the motherboard or a controller
card). DLGDIAG must be run separately to test each WD hard drive in the system.
Depending on your hard drive model and diagnostic requirements, you can use either the
Windows or DOS version of DLGDIAG. Windows and DOS versions of the DLGDIAG
software are available at support.wdc.com/download.
DLGDIAG Options
Windows
Quick Test — performs a quick S.M.A.R.T. self-test to gather and verify the Data
Lifeguard information contained on the drive.
Extended Test — performs a Full Media Scan to detect bad sectors. Test may take several
hours to complete depending on the size of the drive.
Write Zeros — writes zeros to the drive using the Full Erase or Quick Erase option.
Erases all data on the drive by writing zeros to each sector – file system and data will be
lost.
View Test Results — displays results for the last hard drive tested.
DOS
Select Drive — selects the hard drive to test and displays status for all hard drives.
Quick Test — tests the drive quickly for any major physical problems.
Extended Test — checks the drive thoroughly for any major physical problems.
Write Zeros To Drive — wipes any and all data off the drive. Use this option when your
data is no longer usable or recoverable.
View Test Results — displays results for the last hard drive tested.
Print Test Results — prints results for the last hard drive tested (USB printers not
supported).
Log File Open/Close — stores results for all hard drives tested (DLGDIAG.LOG)
Enter & Print RMA Information — enters and prints RMA information for returning a
hard drive to WD.
Help — brief descriptions of each option and explanations of error codes.
Quit — reboot your system once you have completed the selected tasks.

USER MANUAL
When to Use DLGDIAG
If the hard drive reports errors, if you are unable to access files on the hard drive, or if another
diagnostic utility such as SCANDISK, CHKDISK, DEFRAG, or Norton Utilities reports
errors on the hard drive, run DLGDIAG to determine if they are hard drive-related.
DLGDIAG does not report errors associated with the system BIOS, controller card, or
motherboard of your system.
DLGDIAG can be used at any time to test for hard drive errors. If you experience problems
accessing files or encounter other apparent hard drive errors, you can safely run the Quick
Test option to confirm your hard drive integrity.
DLGDIAG’s Repair Drive feature allows the user to restore any errors found during the
Extended Test scan of your hard drive without destroying all data on the drive.
DLGDIAG does not resolve mechanical damage such as noisy drives or drives that do not
spin up. Contact WD technical support (see “Service and Support” on page 19) if you have a
hard drive that exhibits the above difficulties.
Before using DLGDIAG
If used properly, DLGDIAG does not overwrite data on the hard drive during the scan and
will not result in data loss. However, you should always back up your data before running any
diagnostic utility. Back up all data on your hard drives(s) before using DLGDIAG.
CAUTION: Back up all data on your hard drive(s) before using DLGDIAG. You
will erase all data if the Write Zeros To Drive option is invoked.
