Abstract
A method includes adding a key version tag to an encryption key store that stores encryption keys. The key version tag is inserted into a data stream. The data stream including the key version tag is written to media. The data in the data stream is erased by scrambling the encryption keys and incrementing the key version tag in the encryption store by a digit. The data stream is replaced with a replacement data pattern when the key version tag stored in the encryption store and the key version tag located in the data stream mismatch.
