Excerpts from Helxis' Drive Health Help:
Q: What is T.E.C.?
A: T.E.C. is "Threshold Exceeded Condition" and basically it means a disk failure. When your Drive Health software reports a "Nearest T.E.C." you should consider it as a "Failure date".
Q: What is the meaning of the "Nearest T.E.C. unknown" disk status? Is it good or bad?
A: If Drive Health shows you unknown T.E.C. date this means your disk drive is healthy! You only need to continue monitoring of this disk to prevent possible unexpected failure in future.
Q: I've installed Drive Health and it predicted a very close T.E.C. date after a few hours of usage. What should I do?
A: The T.E.C. date prediction is based on a analysis of the parameter degradation history. This means that DH is unable to accurately predict the failure if still there is not enough data accumulated in history about previous parameter state. In our experience it requires at least two weeks of daily disk monitoring, to make accurate failure predictions. Just continue disk monitoring - the T.E.C. date will be changed after a day or two.
