Abstract:
A method of operating a disk drive is disclosed, the disk drive comprising a head actuated over a disk surface, and a first non-volatile semiconductor memory (NVSM). Calibrated parameters are stored in the first NVSM, wherein the calibrated parameters for accessing the disk surface. Prior to altering the disk drive, the calibrated parameters are uploaded from the disk drive to a host. After altering the disk drive, the calibrated parameters are downloaded from the host to the disk drive and the calibrated parameters are stored in a second NVSM.
