Abstract
A method is disclosed in a data processing system for prohibiting unauthorized access of data that is stored on storage drives. Multiple logical partitions are generated. A different unique randomizer seed is associated with each one of the logical partitions. In response to one of the logical partitions needing to access a storage drive, the logical partition transmits a seed to the storage drive. The transmitted seed is associated with the one of the logical partitions. A transmitting one of the logical partitions is unable to transmit a seed that is other than a seed that is associated with the transmitting one of the logical partitions. The storage drive utilizes the transmitted seed to randomize and de-randomize data for the one of the logical partitions. Data randomized for one of the logical partitions cannot be de-randomized for a different one of the logical partitions.
