Abstract:
Various embodiments are provided that enable a controller of a storage device having storage media to perform one or more error recovery operations on the storage media, and to convey, while performing the one or more error recovery operations, a message indicating a status of the one or more error recovery operations to a host processor in communication with the storage device. Storage devices implementing embodiments of the present invention include hard disk drives and solid state disk drives comprising a disk head having a magnetoresistive (MR) element configured to read and write data to and from the storage media, and coupled to an analog/digital (A/D) converter, and the error recovery operations are selected from a list of changing an automatic gain control of the A/D converter, positioning the disk head off-track in order to read the data, and adjusting a bias value of the MR element.
