    Abstract: Data-integrity protection of a cached storage device is provided in an alternate operating system (OS) environment by replacing an actual partition table for a disk with a dummy partition table and scrambling a predetermined amount of data on the cached storage device. The dummy partition table is designed to render data on the disk inaccessible when the dummy partition table is used by an OS to access the data. During operation, the data on the disk can be accessed using information based on the actual partition table. In response to receiving a request to disable caching, the dummy partition table on the disk is replaced with the actual partition table and any scrambled data is unscrambled, thus rendering the data on the formally cached disk accessible in an alternate OS environment where appropriate caching software is not present.

    Abstract translation: 通过用虚拟分区表替换具有虚拟分区表的磁盘的实际分区表,并在缓存存储设备上加扰预定量的数据,在备用操作系统(OS)环境中提供缓存存储设备的数据完整性保护。 当虚拟分区表被OS使用以访问数据时,虚拟分区表被设计为使得磁盘上的数据不可访问。 在操作期间,可以使用基于实际分区表的信息来访问磁盘上的数据。 响应于接收到禁用高速缓存的请求,磁盘上的虚拟分区表被替换为实际分区表,并且任何加扰的数据被解扰,从而使得在正式缓存的磁盘上的数据可在替代操作系统环境中访问,其中适当的缓存软件 不存在
