Abstract
An apparatus and associated method are disclosed for optimizing the data transfer performance of a disc drive in which user data is stored in data blocks arranged on tracks of at least one rotating disc. When a selected, uninterrupted amount of time passes since the most recently performed disc drive operation, the disc drive enters an idle mode and selectively evaluates the data blocks for uncorrected read errors. During the idle mode, at such time that a selected data block is found having an uncorrected error, a sequence of corrective operations are performed in an attempt to resolve the error and the selected data block is reallocated when at least selected one of the corrective actions are unsuccessful.
