1.1 System requirements

The following hardware and software is required to use these drives. Host system requirements:

• Windows XP with Service Pack 2 (or later) when utilizing the Windows DriveTrust API.

• System/BIOS that supports ATA Security commands.

1.2 About Momentus 7200 FDE.2 SATA disc drives

Momentus® 7200 FDE.2 SA TA drives contain DriveTrust technology providing Full Disc Encryption (FDE) using proven Advanced Encryption Standard (AES) data encryption and decryption.

You can elect to use Momentus 7200 FDE.2 SATA drives in one of two different security modes:

1. The ATA Security mode

To operate in ATA Security mode, you only need a host system and operating system that supports the existing ATA Security Command Set. The drive is shipped to operating in this mode, ready to use.

2. The DriveTrust Security mode

To enable a robust enterprise-level security and management policy, you may elect to operate in DriveTrust Security mode. To do so, you will need to use a third-party security application to manage the DriveTrust features. Please contact your system or software provider for more details.

Refer to the table below to determine which mode is best for your particular solution.

FDE drive feature list

• Automatically encrypts (and decrypts) all data on the drive

• Operations are performed with no measurable performance loss

• All user data is encrypted on write operations and decrypted on read operations

FDE benefits

• Drive-level protection of data

• Drives that are stolen, taken out of service, or re-purposed remain fully protected

• Near instantaneous disposal and re-purposing of the drive (ensures that data from previous user is not accessible by the new drive owner)

• Able to be deployed within a trusted computing environment

2 Momentus 7200 FDE.2 SATA Product Manual, Rev. B

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 th at 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 sys tem re au th en tic at es th e us er.

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 posse ssing the drive.

2.7 Seek time

Seek measurements are taken with nominal power at 25°C ambient temperature. All times are measured using drive diagnostics. The specifications in the table below are defined as follows:

• Track-to-track seek time is an average of all

possible single-track seeks in both directions.

• Average seek time is a true statistical random average of at lea st 5,000 measurements of seek s between r

andom tracks, less overhead.

Typical seek times (msec) Read

Track-to-track 1.5 Average 11.0 Full-stroke 22.0 Average latency 4.17

Note. These drives are designed to consistently meet the seek times represented in this manual. Physical

seeks, regardless of mode (such as track-to-track and average), are expected to meet the noted values. However, due to the manner in which these drives are formatted, benchmark tests that include command overhead or measure logical seeks may produce results that vary from these specifications.

2.9.2 Conducted noise

Input noise ripple is measured at the host system powe r

supply across an equivalent 15-ohm resistive load on

the +5 volt line. Using 5-volt power, the drive is expected to operate with a maximum of 100 mV peak-to-peak square-wave

injected noise at up to 10 MHz. Note. Equ

ivalent resistance is calculated by dividing the nominal voltage by the typical RMS read/write

current.

2.9.4 Power-management modes

The drive provides programmable power management to provide greater energy efficiency. In most systems, you can control power management through the system setup program. The drive features the following power-management modes:

Table 4: Power management modes

Power modes Heads Spindle Buffer

Active (operating) Tracking Rotating Full power Idle, performance Tracking Rotating Self refresh—low power Idle, active Floating Rotating Self refresh—low power Idle, low power Parked Rotating Self refresh—low power Standby Parked Stopped Self refresh—low power Sleep Parked Stopped Self refresh—low power

• Active mode

The drive is in Active mode during the read/write and seek operations.

• Idle mode

The buffer remains enabled, and the drive accepts all commands and returns to Active mode any time disc access is necessary.

• Standby mode

The drive enters Standby mode when the host sends a Standby Immediate command. If the host has set the standby timer, the drive can also enter Standby mode automatically after the drive has been inactive for a specifiable length of time. The standby timer delay is established using a Standby or Idle command. In Standby mode, the drive buffer is in Self Refresh Low Power mode, the heads are parked and the spindle is at rest. The drive accepts all commands and returns to Active mode any time disc access is necessary.

•Sleep mode

The drive enters Sleep mode after receiving a Sleep comma nd from the host. In Sleep mode, the drive buffer is in Self Refresh Low Power mode, the heads are parked and the spindle is at rest. The drive leaves Sleep mode after it receives a Hard Reset or Soft Reset from the host. After receiving a reset, the drive exits Sleep mode and enters Standby mode with all current translation parameters intact.

• Idle and Standby timers

Each time the drive performs an Active function (read, write or seek), the standby timer is reinitialized and begins counting down from its specified delay times to zero. If the standby timer reaches zero before any drive activity is required, the drive makes a transition to Standby mode. In both Idle and Standby mode, the drive accepts all commands and returns to Active mode when disc access is necessary.
