摘要： The present invention relates to secure data storage on hard disk drives or other portable or fixed media for computer systems and computing devices. The present invention provides a method of securely storing data on a storage medium (130) storing data for a plurality of users and coupled to a computing device (100), the method comprising: executing firmware program instructions (110) associated with the computing device on powering on of the computing device, and which executing firmware program instructions perform the following: authenticate one of the plurality of users (210); determine (330) a user partition start and end address for the authenticated user from a user partition datastructure (145) which comprises user partition start and end addresses on the storage medium for the plurality of users, and incorporate (220) the determined user partition start and end addresses into a storage medium partition datastructure (125) associated with the storage medium; loading and executing (250, 255) software program instructions (133) for operating the computing device from the storage medium following incorporating of the determined user partition start and end addresses into the storage medium partition datastructure, and which software program instructions require the storage medium partition datastructure (125) for said execution.
