When I run the Smart Data Self-Test disk utility the result indicates Smart Self Test Failed. Yet when I look at the individual test, they all say OK. Did the test itself fail or did the disk fail the test? Running version 12.10 .....
Certain SMART details could have been triggered in the past, this would cause it to pass or fail, but still report everything is fine now. If this is a multi-disk system, pull it and run the manufacturers scripts.
If this is a single disk, continue to test, it is likely an intermittent failure that will appear in full soon enough
