Checking Device Health
The WD Drive Utilities software provides three diagnostic tools to help make sure that
your device is performing well. Run the following tests if you are concerned that your
device is not operating properly:
SMART Status Check
SMART is a failure-prediction function that continuously monitors key internal
performance attributes of the device drives. A detected increase in drive
temperature, noise, or read/write errors, for example, can provide an indication that
the drive is approaching a serious failure condition. With advanced warning, you
could take precautionary measures, like moving your data to another device, before
a failure occurs.
The result of a SMART status check is a pass or fail evaluation of the drives’
condition.
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 device diagnostic is the complete drive test. It checks
every sector of each device drive 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 device. And, because they are so fast, running
the SMART 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.
