  • Publication number: 20120254264
    Abstract: Storage drive logic and a standalone tape file structure are described. File transfer logic transfers file data to and from a network according to a first protocol. Media access logic accesses a sequential-access storage medium associated with the drive according to a second protocol. Media management logic translates file-based commands received from the network according to the first protocol into sequential-access device commands according to the second protocol. The device commands control accessing of data by the drive. The storage medium may be a magnetic tape including a data region for storing data in a file format, and a table of contents (TOC) region for storing a table of contents that indexes the locations of files within the data region.

  • Publication number: 20070130477
    Abstract: Data stored on a removable storage medium such as a tape cartridge can be protected from unauthorized access by storing a password hash value in a protected manner on the storage medium, where the password hash value is generated from a password by a one-way hash function such as SHA-256, so that the password cannot easily be determined from the hash value. A media drive is then equipped with logic for blocking access to the data unless the password is provided. The password is protected from unauthorized access because the password hash value, not the password itself, is stored on the storage medium.
