• Quick Drive Test
Each device drive has a built-in Data Lifeguard™ diagnostic utility that tests the
drive for error conditions. The quick drive test checks the drives for major
performance problems.
The result of a quick drive test is a pass or fail evaluation of the drives’ condition.
• Complete Drive Test
The most comprehensive drive diagnostic is the complete drive test. It checks
every sector for error conditions, and inserts bad sector markers as required.
The best time to run the drive diagnostics and status checks is on a regular basis, before
you encounter any problems with your drives. And, because they are so fast, running the
S.M.A.R.T. status check and the quick drive test provides a high level of assurance with
minimal inconvenience. Then, run all three whenever you encounter disk error conditions
when writing or accessing files.
To run drive diagnostics and status checks:
1. Click Go > Applications > WD Drive Utilities to display the WD Drive Utilities screen
(see Figure 3 on page 9).
2. If you have more than one supported drive or storage device connected to your
computer, select the one that you want to check.
3. Click Diagnostics to display the Diagnostics dialog:
4. On the Diagnostics dialog, click the button for the test that you want to run:
