    摘要: A disk is manufactured having a reduced capacity based on a quantity of addressable and non-addressable portions. The method of formatting the disk comprises identifying a first quantity of the storage portions; and labeling the first quantity of storage portions as non-addressable storage portions such that the non-addressable storage portions cannot be accessed by a user or a disk drive. The first quantity of storage portions may include addressable portions designated as non-addressable portions.

    摘要: Data on a master is read into a master image file, and the master image file is manipulated to include a benchmark comprising tracking and verification information tied to at least a portion of the master image file. Thus, a copied-to storage media as copied from the master image file also includes such benchmark, a data alteration of the master image file causes a mis-match with regard to the benchmark in such master image file, and a data alteration of the copied-to storage media also causes a mis-match with regard to the benchmark in such storage media as copied from such master image file. The benchmark may include a part identifier and a security identifier.

    摘要: Methods are provided for preventing data from being written to a data sector that has been identified as faulty on a disk in a disk drive system. It is first determined whether data of a data sector of a portion of a disk is recoverable. If the data is non-recoverable, an invalid logical ID is written to the logical block address (LBA) corresponding to the data sector thereby identifying the data sector as faulty and preventing data from being written at the data sector. The LBA is then reallocated to point to a different data sector if the data is non-recoverable. Thus, further data directed to the LBA will be written to the different data sector responsive to the reallocated LBA, thereby avoiding writing the new data to the data sector identified as faulty. Internal drive read re-tries can still take place on the faulty data sector even after the LBA has been assigned an invalid logical ID.
