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 and 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.
