Abstract
Various embodiments of the present invention that include arranging a first storage device and second storage device to store data in a mirrored configuration. Upon receiving a message indicating that the first storage device is in an error recovery mode, the host processor can convey a second request to read the data from the second storage device. The storage device is selected from a list comprising a hard disk drive and a solid state disk drive, and the hard disk drive comprises 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 wherein the error recovery operation is selected from a list comprising 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.
