An invention is provided for protecting the data integrity of a cached storage device in an alternate operating system (OS) environment. The invention includes replacing an actual partition table for a disk with a dummy partition table. 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, thus rendering the data on the formally cached disk accessible in an alternate OS environment where appropriate caching software is not present. |
