5.10REVERTSP
SED models will support the RevertSP feature which erases all data in all bands on the device and returns the contents of all SPs (Security Providers) on the device to their original factory state. In order to execute the RevertSP method the unique PSID (Physical Secure ID) printed on the drive label must be provided. PSID is not electronically accessible and can only be manually read from the drive label or scanned in via the 2D barcode.
5.11ATA SECURITY ERASE UNIT COMMAND ON SED SATA DRIVES
The ATA SECURITY ERASE UNIT command shall support both the Normal and Enhanced erase modes with the following modifications/ additions:
•Normal Erase: Normal erase shall be accomplished by changing the media encryption key for the drive followed by an overwrite opera- tion that repeatedly writes a single sector containing random data to the entire drive. The write operation shall bypass the media encryp- tion. On reading back the overwritten sectors, the host will receive a decrypted version, using the new encryption key, of the random data sector (the returned data will not match what was written).
•Enhanced Erase: Enhanced erase shall be accomplished by changing the media encryption key for the drive.
5.12SANITIZE DEVICE - CRYPTO SCRAMBLE EXT
This command cryptographically erases all user data on the drive by destroying the current data encryption key and replacing it with a new data encryption key randomly generated by the drive. Sanitize Device is a command field B4h and Feature field 0011h (CRYPTO SCRAMBLE EXT).
The drive shall support the Sanitize Feature Set as defined in ANSI/INCITS
The drive shall not support the OVERWRITE EXT and BLOCK ERASE EXT
Support of the SANITIZE FREEZE LOCK EXT command shall be determined on a
