Abstract
A process, apparatus, and system are disclosed that allow information to be passed between software modules in different partitions in an environment for a predetermined operating system (OS) and an area hidden from the operating system (OS) in a storage device, such as hard disk drive (HDD). The computer system may include a hard disk drive (HDD) that meets a protected area run time interface extension services (PARTIES) specification and that has an access environment for an operating system (OS) and a PARTIES partition. The PARTIES partition is an area hidden from the operating system (OS). The computers system also includes a CMOS/NVRAM that provides a work area for communication between a user mode module, operating in the access environment for the operating system (OS) in a user data management application, and a management mode module, operating in an environment corresponding to the hidden area.
