Abstract
Processor-based systems may use more than one operating system and may have disk drives which are cached. Systems which include a write-back cache and a disk drive may develop incoherent data when operating systems are changed or when disk drives are removed. Scrambling a partition table on a disk drive and storing cache identification information may improve data coherency in a processor-based system.
