摘要： A thermally compensated fluid dynamic bearing motor includes a stationary member and a rotatable member rotatable about the stationary member. A hub is coupled with the rotatable member and includes ceramic material with a first coefficient of thermal expansion, wherein the hub is operable to be coupled with a data storage disk. Further the first coefficient of thermal expansion is substantially equal to a second coefficient of thermal expansion of the data storage disk.

摘要： A method of performing predictive failure analysis (PFA) for a disc drive includes maintaining at least two primary error counts during operation of the disc drive. The primary error counts each correspond to disc drive errors associated with different attributes of the disc drive and are potentially indicative of disc drive failure. Imminent disc drive failure is predicted based upon a combination of the primary error counts.
