The files on your My Book drive are important to you. The WD SmartWare software has
several built-in diagnostic tools to help make sure that your drive is performing well. Run
the following tests if you are concerned that your drive is not operating properly:
Diagnostic Tool
Quick S.M.A.R.T.
Status Check
Quick Drive Test
Complete Drive Test The most comprehensive drive diagnostic is the complete drive test. It
The best time to run the drive diagnostics and status checks is on a regular basis, before
you encounter any problems with your drive. And, because they are so fast, running the
quick 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 backing up or retrieving files.
To run drive diagnostics and status checks:
1.
On the Drive Settings screen (see Figure 17 on page 27), click Diagnostics to display
the Run Diagnostics dialog:
2. Click the button for the test that you want to run:
• Quick SMART Status

Description
S.M.A.R.T. is a failure-prediction function that continuously monitors key
internal performance attributes of the drive. A detected increase in drive
temperature, noise, or read/write errors, for example, can provide an
indication that the drive might be approaching a serious failure condition.
With advanced warning, you could take precautionary measures, like
moving your data to another drive, before a failure occurs.
The result of a quick S.M.A.R.T. status check is a pass or fail evaluation of
the drive's condition.
The S.M.A.R.T. status check completes within a second or two.
Your My Book drive has a built-in Data Lifeguard diagnostic utility that
tests the drive for error conditions. The quick drive test checks the drive
for major performance problems.
The result of a quick drive test is a pass or fail evaluation of the drive's
condition.
The quick drive test can take several minutes to complete.
methodically tests every sector for error conditions, and inserts bad-
sector markers as required.
The complete drive test can take several hours to complete, depending on
the size and data configuration of your drive.
