Abstract
A storage device restricts host access to data on the storage device. A controller on the storage device determines that a session protection feature is enabled on the storage device, initiates a session on the storage device, and sets a timer to an initial time. The controller obtains a session timeout value, calculates a session time, and stores the session time in a master index page. The controller further determines when a power reset has occurred and that the storage device is unlocked, initializes the timer with a session time value stored in the master index page prior to the power reset, and continues to calculate the session time. The controller compares the session time with the session timeout value and locks the storage device when the session time exceeds the session timeout value.
