Western Digital Data Lifeguard Diagnostics
Western Digital Data Lifeguard Diagnostics is free hard drive testing software designed for Western Digital branded hard drives. Data Lifeguard Diagnostic will also run diagnostics on hard drives from other manufacturers as long as the primary drive is Western Digital.
The Western Digital Data Lifeguard Diagnostic software installs on Windows operating systems and allows for a number of hard drive tests. See the installation instructions from Western Digital in the link below for details.
How can you use Windows Data Lifeguard Diagnostics to do the following:
1. Perform a quick test on a drive for problems
2. Get the serial number of a drive
3. Write zeros to a drive
4. Peform a full media scan on the drive for bad sectors
* 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.
The Windows version of the Data Lifeguard Diagnostics utility can perform drive identification, diagnostics, and repairs on a Western Digital FireWire, EIDE, Serial ATA, and USB drive. In addition, it can provide you with the drive's serial and model numbers.
