Checking Drive Health
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:
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.
Diagnostic Tool Description
Quick S.M.A.R.T. Status Check 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.
Quick Drive Test 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.
Complete Drive Test The most comprehensive drive diagnostic is the complete
drive test. It methodically tests each 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.
