Abstract
The embodiments described herein generally relate to methods and systems for using an extended patching procedure for correction or repair of logical data portions, pages, or sectors of a computer data storage device. The extended patching procedure targets for repair not only the page(s) appearing to be defective or unusable based on a failed read operation for a data transfer request, but also additional pages. Determining the additional pages to include for automatic patching is based on: statistical distribution analyzes to include pages within the physical or logical vicinity of the original page, information about the underlying storage device technology or Input/Output (I/O) subsystem, and/or historical data about error conditions for areas related to the original page. Preemptively patching pages based on extended page lists improves system performance by reducing the total number of costly repair processes and by avoiding situations involving correction actions that fail to resolve.
