Abstract
A tape drive apparatus has a data transfer apparatus for transferring data between a loaded tape medium and the tape drive apparatus. A data processing apparatus is coupled to the data transfer apparatus for formatting the loaded tape medium. The formatting of the tape medium is performed using an identifier of the tape medium. For example, the identifier is written together with the formatting information onto the tape medium for later reference.

A library for storing and retrieving removable information storage elements, the removable information storage elements having format information comprising an information storage element identifier, the library comprising:
- an array of storage cells for storing the removable information storage elements,
- at least one drive for reading the format information from the removable information storage elements,
- an accessor for transporting the removable information storage elements between the storage cells and the at least one drive,
- a controller operable to:
- a) direct the accessor to move one of the removable information storage elements from its storage cell to the at least one drive,
- b) direct the drive to provide the format information comprising the information storage element identifier,
- c) enter the information storage element identifier into a cartridge map,
- wherein each of the removable storage elements is formatted into fragments, the controller being operable to create the information storage element identifier for a removable information storage element when the controller determines the removable information storage element to be unformatted, the information storage element identifier being used to format the removable storage element.
A library controller for storing and retrieving removable information storage elements, the removable information storage elements having format information comprising an information storage element identifier, the library controller operable to:
