Abstract: Method and apparatus for predicting data storage device failures using adaptive failure prediction modeling. In some embodiments, monitored parameters are used to predict a potential imminent failure of a first data storage device using a first copy of a first failure prediction model (FPM). Data associated with the predicted potential imminent failure are transferred by the device across a computer network to a host device. The host device generates an updated, second FPM responsive to the transferred data as well as from data from at least a second data storage device transmitted across the computer network having a second copy of the first FPM. A first copy of the updated, second FPM is transferred, via the network, for use by the second data storage device.

Abstract: Zones of a magnetic recording medium are allocated as a respective plurality of distributed media caches arranged in in a predetermined order. For each of a plurality of caching events, cache data is written to one or more of the distributed media caches. A next of the media caches in the predetermined order is selected for the next caching event if the selected caches are not a last in the predetermined order. Otherwise a first media cache is selected in the predetermined order.

Abstract: Method and apparatus adaptively adjusting power levels of a data transducer in a data storage device. In some embodiments, an initial power value is applied to a powered element of a transducer to write user data from a host device to a rotatable data recording medium. An exception condition is declared responsive to a measured parameter. The transducer is used to read data from an evaluation track using a range of different input power values for the powered element. A different, new power value is selected for the powered element responsive to an error rate associated with each of the range of different input power values, with the new power value being lower than the initial power value. Thereafter, the new power value is applied to the powered element during a subsequent writing of user data to the rotatable data recording medium.
