The drive encrypts every write operation and decrypts every read operation without user intervention. The

encryption and decryption is done on the drive itself, so there is a near-zero performance impact when the

drive writes and reads data. The performance-optimized encryption and decryption engine performs at the

SATA interface speed.

The purpose of full disc encryption on the drive is to protect the data stored on the drive in the event that the

host system is lost or stolen. This data at rest protection assures the system owner that if their system is lost or

stolen, their data will not be accessible without the correct credentials.

Note.

The system reauthenticates the user on powerup and when awakening from sleep mode. It is not

necessary to power down to ensure that the system reauthenticates the user.

Having the encryption/decryption on the drive also provides the highest level of security for data because all

data, including the boot sector bytes, operating system, temp and even the swap files are encrypted at the

drive level.

1.2.1

Drive state upon shipment

Upon shipment from the Seagate factory, the ATA Security Interface is enabled and functioning. This is

referred to as operating in ATA Security mode. The following is the detailed state of the drive upon shipment.

•

Full Disc Encryption is active and functioning. All user data is encrypted on write and decrypted on read.

•

The user interface to the drive is active and all read and write commands are allowed.

•

The ATA user password is null (no value).

•

The ATA master password is set to the Security ID (SID).

•

ATA Security is set to the unlocked state. No password is required to access the drive.

Momentus 7200 FDE.2 SATA

drives may be integrated into the computer system in the same way you would

integrate a non-FDE Momentus drive.

The encryption key is enabled and operational when the drive leaves the Seagate factory. No user id is

required to access the drive, so the data on the drive is accessible to anyone possessing the drive.
