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.
