Volitans has published v2.0 of SMART Utility, a diagnostic tool for hard drives. The software taps into the SMART monitoring technology built into hard drives, and presents status information in a more convenient and legible form. The app additionally attempts to warn users about impending disk failures, with the aim of allowing time to transfer material to a different location.
New to v2.0 are the ability to run built-in self-tests, and preferences that can limit alerts to the discovery of new problems.

SMART Utility requires Mac OS X 10.4 or better, and costs $25.
