Western Digital Data Lifeguard Diagnostics 1.31.0 + Portable

Western Digital Data Lifeguard Diagnostics for Windows is a simple tool from Western Digital that displays the model, serial number, partitions, capacity, and S.M.A.R.T. data of any Western Digital hard disk drives that support Data Lifeguard that are attached to your system. It can also test your disks and display the results.

We extracted and clicked the executable file, and the program quickly opened and scanned our system, displaying our three WD physical drives in the upper view and the logical drives by letter in the lower view. We could initiate a test or view S.M.A.R.T. data by clicking a small icon. We selected a disk for testing, which consisted of three options: Quick Test, which verifies Data Lifeguard information; Extended Test, which performs a Full Media Scan and can take hours on a large drive; and Write Zeros, which essentially erases the drive by overwriting the data with zeroes. Another control displays test results. We selected Quick Test, pressed Start, and a pop-up warning advised us to close any open files and programs on the drive to prevent data loss. We clicked OK to proceed, and the program displayed a small pop-up with a progress bar, an estimated time of 2 minutes, and an Elapsed Time counter, which showed 1:57 when the test finished, beating the estimate by three seconds. Clicking a drive’s entry under S.M.A.R.T. called up its S.M.A.R.T. data. Clicking Help called up a typically clean and concise WD documentation sheet. Other than a Web link and Close button, that’s about it.

Western Digital is one of the major suppliers of hard drives to the computer industry, and a lot of WD drives are spinning away as we speak. If you use WD drives, either in desktop or laptop or Blue, Green, or Black, Data Lifeguard Diagnostic can help you keep them spinning happily for many years.

Features of Western Digital Data Lifeguard Diagnostics

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.

Extended Test:
• For most computers the DLGDIAG Extended Test takes 30 minutes to an hour 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. This is not a destructive test unless users select repair function when bad sectors are detected.

Write Zeros:
• This option can be used to erase operating systems and file systems. The QUICK ERASE writes zeros to the first and last million of sectors and the FULL ERASE writes zeros to the entire drive and may take hours to complete depending on the drive size and system performance.

View Test Results:
• The current test results can be displayed with this function. Test results will be overwritten once a new test is started.
