WD Data LifeGuard Diagnostics

WD Data LifeGuard Diagnostics is a Windows utility for examining Western Digital storage devices connected inside or outside a PC. It can help users investigate a disk error, review a drive’s reported condition, or identify a device before maintenance. For each listed drive, it presents details such as its model, serial number, and capacity.

Short and extended checks help users assess a drive when they suspect a disk problem.

Users select a drive from the list and choose either a short diagnostic check or a longer examination of the disk surface. The utility also presents SMART readings and partition details. An overwrite option fills a selected drive with zeroes, removing its existing contents; users should confirm which disk they have selected before starting that operation.

Features:

• Lists connected Western Digital drives
• Shows model, serial number, and capacity
