Abstract
A method and apparatus for error recovery in various computer data storage devices that are associated with a host computer operating system includes an error recovery module that is coupled to each device driver in the host operating system. When one of the devices reports an error in the form of sense bytes to its associated device driver, the device driver sends the sense bytes and device type identification to the error recovery module. In turn, the error recovery module generates an action token based upon the sense bytes and device type, and then correlates the action token with error recovery actions. The device driver then executes the error recovery actions. Thus, a common error recovery module can be used in conjunction with a large variety of data storage devices.
