12.7.1 Restricted/Unrestricted Secure Erase

For the Sanitize erase patterns (Overwrite, Block Erase, Crypto Scramble), the following erase methods are applicable if your drive supports the method:

  • Restricted: the drive will be unusable until the sanitize operation is completed successfully. If a restricted sanitize operation fails, you are only allowed to start another sanitize operation.

  • Unrestricted: the drive will be recoverable in the case that the sanitize erase operation fails. Data may still be present on the drive. Not all drives support this sanitize method.
