Abstract
A disk drive subsystem is disclosed that implements a process for metadata recovery. Certain embodiments relate to recovery of metadata containing information indicating the physical locations in the disk drive in which host data is stored. In an embodiment, the metadata to be recovered is disposed in sequence with, or in physical association with host data that it describes. Recovery is accomplished by identifying metadata that is valid, but is absent from one or more translation tables containing translation information. Metadata portion can include one or more identifiers that are sequentially related to identifiers included in one or more other metadata portions. Performance improvements can thereby be attained.
