摘要: A method of inhibiting inadvertent and unauthorized writing and reading of information to and from a storage medium comprises the steps of (a) writing a first code in a predetermined location on the storage medium, the first code being indicative of a first protection mode of the storage medium (112); (b) receiving a command to change the protection mode of the storage medium from the first protection mode to a second protection mode (118); and, in response to the command, (c) writing in the predetermined location on the storage medium, in place of the first code, a second code indicative of the second protection mode (136, 138). A protection mode can inhibit writing to the storage medium, both writing and reading to and from the medium, or neither. Changing of protection modes can also be password protected.

摘要: An apparatus and method for enabling/disabling selective features of a disk drive is provided. A data structure contained on a disk is read by the drive and based on this data structure, selective features of the drive are manipulated to improve the performance of the disk drive. The data structure is preferably disposed on a portion of the disk that is inaccessible to the host computer system. Additionally, the data structure preferably is read by the drive during disk insertion or activation and used to enable and/or disable features of the drive.
