Abstract: A failure of a head is detected, the head reading from and writing to an affected surface of a disk of a disk drive. The failure prevents the head from writing to the affected surface but does not prevent the head from reading from the affected surface. In response to detecting the failure, a remediation is performed. The remediation involves determining spare capacity blocks on other surfaces of the disk drive different than the affected surface, and copying data from the affected surface to the spare capacity blocks via an internal copy function within the disk drive. The spare capacity blocks in place of the affected surface for data storage and retrieval subsequent to the failure.
