In addition to providing a locking mechanism to prevent unwanted firmware download attempts, the drive also only accepts 
download files which have been cryptographically signed by the appropriate Seagate Design Center.

Three conditions must be met before the drive will allow the download operation:
1. The download must be an SED file. A standard (base) drive (non-SED) file will be rejected.

2. The download file must be signed and authenticated.

3. As with a non-SED drive, the download file must pass the acceptance criteria for the drive. For example it must be appli-

cable to the correct drive model, and have compatible revision and customer status.

The standard drive models and the SED drive models have identical hardware, however the security and encryption portion 
of the drive controller ASIC is enabled and functional in the SED models. This represents a small additional drain on the 5V 
supply of about 30mA and a commensurate increase of about 150mW in power consumption. There is no additional drain on 
the 12V supply. See the tables in Section 6.3 for power requirements on the standard (non-SED) drive models.

The SED models support the following two commands in addition to the commands supported by the standard (non-SED) 
models as listed in Section 8.9, "Supported commands":
• Security Protocol Out (B5h)
• Security Protocol In (A2h)

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 CRYPTOGRAPHIC ERASE is a SCSI 
CDB Op code 48h and selecting the service action code 3 (CRYPTOGRAPHIC ERASE)

The 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.
