Are Drive Health predictions accurate?
Drive Health can only predict a gradual degradation of the disk. It cannot and it does not predict catastrophic events, including but not limited to head crashes, power spikes and so on. There is a general rule to follow when interpreting Drive Health results: If Drive Health reports a close T.E.C. date , it’s time to begin backup of critical data.

A: “Spin up time” describes amount of time it took to spin the platters up to their rated rotation speed (usually 5400 or 7200 RPM). Values above 80 should be considered good. Values between 70 and 80 are still acceptable. There is a known issue with Quantum (Maxtor) hard drives – out-of-the-box new drives drop “Spin up time” to 70 within first two weeks of use, causing program to predict failure within a month. This is usually a false alarm. After some initial “burn-in” period “Spin up time
