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.

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.

A system and methods for providing offset information on a storage medium are provided by writing at least one unalterable mark on the storage medium during a manufacturing formatting process. The unalterable mark(s) are variably offset from a fixed position. The amount of offset represents a first source of unique information. The unalterable mark(s) themselves comprise a second source of information. Both sources of information are combinable and may be utilized in connection with the generation of a unique serial number for the storage medium or for other digital rights management purposes.
