Data are accessed securely in a data storage device that includes a non-volatile solid-state storage device integrated with a magnetic storage device. An identical copy of drive security data, such as an encrypted version of a drive access password, is stored in both the non-volatile solid-state storage device and in the magnetic storage device. In response to receiving a command from a host device that results in access to the magnetic storage device, access is granted to the magnetic storage device if the copy of drive security data stored in the non-volatile solid-state storage device matches the copy of drive security data stored in the magnetic storage device. Furthermore, encrypted drive-unique identification data associated with the drive may be stored in both the non-volatile solid-state storage device and the magnetic storage device, and access is granted if both copies of the encrypted drive-unique identification data match.

Secure data access in hybrid disk drive

A display unit is constituted by a passive matrix of independently controllable pixels characterized by an active area of n rows and m columns of discrete pixels and a pixel border. The pixel border has a predetermined width, in one embodiment two pixels. The border pixel color state is controlled herein by the frame buffer memory. The pixel border color state is controlled to correspond to information contained in a frame buffer memory locus. This locus may be, in various embodiments herein, a single pixel, a row of pixels, or a number of rows of pixels of frame buffer memory. Each row of pixels may be equal to m and/or n. In one embodiment, the frame buffer controls the border pixels directly via a liquid crystal display controller and drivers, without a timing generation mechanism, such as a timing ASIC.
