Seagate BarraCuda Product Manual, Rev. A 7 www.seagate.com Introduction
1.1 About the SATA interface
The Serial ATA (SATA) interface provides several advantages over the traditional (parallel) ATA interface. The primary advantages include:
- Easy installation and configuration with true plug-and-play c onnectivity. It is not necessary to set any jumpers or other configuration options.
- Thinner and more flexible cabling for improved enclosure airflow and ease of installation.
- Scalability to higher performance levels. In addition, SATA makes the transition from parallel ATA easy by providing legacy software support. SATA was designed to allow users to install a SATA host adapter and SATA disk drive in the current system and expect all of the existing applications to work as normal. The SATA interface connects each disk drive in a point-to-p oint configuration with the SATA host adapter. There is no master/slave relationship with SATA devices like there is with parallel ATA. If two drives are attached on one SATA host adapter, the host operating system views the two devices as if they were both “masters” on two separate ports. This essentially means both drives behave as if they are Device 0 (master) devices. The SATA host adapter and drive share the function of emulating parallel ATA device behavior to provide backward compatibility with existing host systems and software. Th e Command and Control Block registers, PIO and DMA data transfers, resets, and interrupts are all emulated. The SATA host adapter contains a set of registers that shadow the contents of the traditional device registers, referred to as the Shadow Register Block. All SATA devices behave like Device 0 devices. For additional information about how SATA emulates parallel ATA, refer to the “Serial ATA International Organization: Serial ATA Revision 3.2” . The specification can be downloaded from www.sata-io.org. Note The host adapter may, optionally, emulate a master/slave environment to host software where two devices on separate SATA ports are represented to host software as a Device 0 (master) and Device 1 (slave) accessed at the same set of host bus addresses. A host adapter that emulates a master/slave environment manages two sets of shadow registers. This is not a typical SATA environment.

2.8.3 Voltage tolerance
Voltage tolerance (including noise):
- 5 V ± 5 %
- 12V +10% / -7.5%
2.8.4 Power-management modes
The drive provides programmable power management to provid e greater energy efficiency. In most systems, users can control power management through the system setup prog ram. The drive features the following power-management modes:
- A c t i v e m o d e The drive is in Active mode during the read/write and seek operations.
- Idle mode The buffer remains enabled, and the drive accepts all comm ands and returns to Active mode any time disk access is necessary.
- S t a n d b y m o d e The drive enters Standby mode when the host sends a St andby Immediate command. If th e 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 Id le command. In Standby mode, the drive buffer is enabled, the heads are parked and the spindle is at rest . The drive accepts all commands and returns to Active mode any time disk access is necessary.
- S l e e p m o d e The drive enters Sleep mode after receiving a Sleep command from the host. In Sleep mode, the drive buffer is dis- abled, 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 trans- lation parameters intact.
- Idle and Standby timers Each time the drive performs an Active function (read, wr ite or seek), the standby time r 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 St andby mode, the drive accepts all com- mands and returns to Active mode when disk access is necessary. Power modes Heads Spindle Buffer Active Tracking Rotating Enabled Idle Tracking Rotating Enabled Standby Parked Stopped Enabled Sleep Parked Stopped Disabled

2.10 Acoustics
Drive acoustics are measured as overall A-weighted acoustic sound power levels (no pure tones). All measurements are consistent with ISO document 7779. Soun d power measurements are taken under essentially free-field conditions over a reflecting plane. For all tests, the drive is oriented with the cover facing upward. operational levels.
2.10.1 Test for Prominent Discrete Tones (PDTs)
Seagate follows the ECMA-74 standards for measurement and iden tification of PDTs. An exception to this process is the use of the absolute threshold of hearing. Seagate uses this threshold curve (originated in ISO 389-7) to discern tone audibility and to compensate for the inaudible components of sound prior to computation of tone ratios according to Annex D of the ECMA-74 standards.
2.11 Electromagnetic immunity
When properly installed in a representative host system, the drive operates without errors or degradation in performance when subjected to the radio frequency (RF) environments defined in Table 5. Note For seek mode tests, the drive is placed in seek mode only. The number of seeks per second is defined by the following equation: (Number of seeks per second = 0.4 / (average latency + average access time Table 4 Fluid Dynamic Bearing (FDB) motor acoustics Idle* Seek

2.15 Corrosive environment
Seagate electronic drive components pass accelerated corrosion testing equivalent to 10 years exposure to light industrial environments containing sulfurous gases, chlorine and ni tric oxide, classes G and H per ASTM B845. However, this accelerated testing cannot duplicate ev ery potential application environment. Users should use caution exposing any electronic components to uncontrolled chemical pollutants and corrosive chemicals as electronic drive component reliability can be affected by the inst allation environment. The silver, copper, nickel and gold films used in Seagate products are especially sensitive to the presence of sulfide, chloride, and nitrate contaminants. Sulfur is found to be the most damaging. In addition, electronic co mponents should never be exposed to condensing water on the surface of the printed circuit board assembly (PCBA) or exposed to an ambient relative humidity greater than 95%. Materials used in cabinet fabrication, such as vulcanized rubber, that can ou tgas corrosive compounds should be minimized or eliminated. The useful life of any electronic equipment may be extended by replacing materials near circuitry with sulfide-free alternatives.

3.0 Configuring and Mounting the Drive
This section contains the specifications and instructions for configuring and mounting the drive.
3.1 Handling and static-discharge precautions
After unpacking, and before installation, the drive may be exposed to potential handling and electrostatic discharge (ESD) hazards. Observe the following standard handling and static-discharge precautions: Caution
- Before handling the drive, put on a grounded wrist strap, or ground oneself frequently by touching the metal chassis of a computer that is plugged in to a grounded outlet. Wear a grounded wris t strap throughout the entire installation procedure.
- Handle the drive by its edges or frame only.
- The drive is extremely fragile—handle it with care. Do not press down on the drive top cover.
- Always rest the drive on a padded, antistatic surface until mounting it in the computer.
- Do not touch the connector pins or the printed circuit board.
- Do not remove the factory-installed labels from the drive or cover them with additional labels. Removal voids the warranty. Some factory-installed labels contain information needed to se rvice the drive. Other labels are used to seal out dirt and contamination.
3.2 Configuring the drive
Each drive on the SATA interface connects point-to-point with the SATA host adapter. There is no master/slave relationship because each drive is considered a master in a point-to-point relationship. If two drives are attached on one SATA host adapter, the host operating system views the two devices as if they were both “masters” on two separate ports. Both drives behave as if they are Device 0 (master) devices. SATA drives are designed for easy installation. It is usually not necessary to set any jumpers on the drive for proper operation; however, if users connect the drive and receive a “drive not detected” error, the SATA-equipped motherboard or host adapter may use a chipset that does not support SATA speed autonegotiation.
3.3 SATA cables and connectors
The SATA interface cable consists of four conductors in two differential pairs, plus three ground connections. The cable size may be 30 to 26 AWG with a maximum length of one meter (39.37 inches). See Table 7 for connector pin definitions. Either end of the SATA signal cable can be attached to the drive or host. For direct backplane connection, the drive connectors are inserted directly into the host receptacle. The drive and the host receptacle incorporate features that enable the direct connection to be hot pluggable and blind mateable. For installations which require cables, users can connect the drive as illustrated in Figure 1. Figure 1 Attaching SATA cabling Each cable is keyed to ensure correct orientation. BarraCuda drives support latching SATA connectors. Power cable Signal cable Signal connector Power connector

3.4 Drive mounting
Users can mount the drive in any orientation using four screws in the side-mounting holes or four screws in the bottom- mounting holes. Refer to Figure 2 and Figure 3 for drive mounting dimensions. Follow these important mounting precautions when mounting the drive:
- Allow a minimum clearance of 0.030 inches (0.76mm) around the entire perimeter of the drive for cooling.
- Use only 6-32 UNC mounting screws.
- The screws should be inserted no more than 0.120 inch (3.05mm) into the bottom or side mounting holes.
- Do not overtighten the mounting screws (maximum torque: 6 inch-lb). Figure 2 Mounting dimensions (2 /3-disk: 2TB to 3TB models) Note Drawings are for mounting hole reference only. PCBA show in pictorial only and can vary based on specific customer configurations. TOP OF LABEL

Seagate BarraCuda Product Manual, Rev. A 26 www.seagate.com About (SED) Self-Encrypting Drives
4.0 About (SED) Self-Encrypting Drives
Self-encrypting drives (SEDs) offer encryption and security services for the protection of stored data, commonly known as "data at rest" . These drives are compliant with the Trusted Computing Group (TCG) Opal Storage Specifications as detailed in the following:
- TCG Storage Architecture Core Specification, Version 2.0 (see www.trustedcomputinggroup.org)
- TCG Storage Security Subsystem Class Opal Specification, Version 2.0 (see www.trustedcomputinggroup.org) In case of conflict between this document and any referenced document, this document takes precedence. The Trusted Computing Group (TCG) is a standards organizati on sponsored and operated by companies in the computer, storage and digital communications industry. Seagate's SED models comply with the standards published by the TCG. To use the security features in the drive, the host must be capable of constructing and issuing the following two SATA commands:
- T r u s t e d S e n d
- T r u s t e d R e c e i v e These commands are used to convey the TCG protocol to and from the drive in their command payloads. Seagate Secure SEDs also support TCG Single User Mode, which can be disabled.
4.1 Data Encryption
Encrypting drives use one inline encryption engine within each drive employing AES-256 algorithms in Cipher Block Chaining (CBC ) mode to encrypt all data prior to being written on the media and to decrypt all data as it is read from the media. The encryption engine is always in operation and cannot be disabled. The 32-byte Data En cryption Key (DEK) is a random number which is generated by t he drive, never leaves the drive, and is inaccessible to the host system. The DEK is itself encrypted when it is stored on the media and when in volatile temporary storage (DRAM), which is external to the en cryption engine. A unique data encryption key is used for each of the drive's possible16 data bands (see Section 4.5 Data Bands (TBD)).
4.2 Controlled Access
The drive has two security providers (SPs) called the "Admin SP" and the "Locking SP ." These act as gatekeepers to the drive se curity services. Security-related commands will not be accepted unless th e user provides the correct credentials to prove that they ar e authorized to perform the command.
4.2.1 Admin SP
The Admin SP allows the drive's owner to enable or disable firmware download operations (see Section 4.4 Drive Locking). Access to the Admin SP is available using the SID (Secure ID) password.
4.2.2 Locking SP
The Locking SP controls read/write access to the media and the cr yptographic erase feature. Access to the Locking SP is available using the Admin or User passwords.
4.2.3 Default password
When the drive is shipped from the factory, all passwords are set to the value of MSID. This 32-byte random value can only be read by the host electronically over the interface. After receipt of the drive, it is the responsibility of the owner to use the default MS ID password as the authority to change all other passwords to unique owner-specified values.
4.2.4 ATA Enhanced Security
The drive can utilize the system's BIOS through the ATA Security API for cases that do not require password management and additional security policies. Furthermore, the drive's ATA Security Erase Unit command shall su pport both Normal and Enhanced Erase modes with the following modifications/additions: Normal Erase: Normal erase feature shall be performed by changing the Data Encryption Key (DEK) of the drive, followed by an overwrite operation that repeatedly writes a single sector containing random data to the entire drive. This write operation bypasses the media encryption. On reading back the overwritten sectors, the host will receive a decrypted version, using the new DEK of the random data sector (the returned data will not match what was written). Enhanced Erase: Enhanced erase shall be performed by changing the Data Encryption Key of the drive.
4.3 Random Number Generator (RNG)
The drive has a 32-byte hardware RNG that it is uses to derive encryption keys or, if requested to do so, to provide random num bers to the host for system use, including using these numbers as Authentication Keys (passwords) for the drive's Admin and Locking SPs.
Seagate BarraCuda Product Manual, Rev. A 27 www.seagate.com About (SED) Self-Encrypting Drives
4.4 Drive Locking
In addition to changing the passwords, as described in Section 4.2.3 Default password , the owner should also set the data access controls for the individual bands. The variable "LockOnReset" should be set to "PowerCycle" to ensu re that the data bands will be locked if power is lost. In addi tion "ReadLockEnabled" and "WriteLockEnabled" must be set to true in the locking table in order for the bands "LockOnReset" setting of "PowerCycle" to actually lock access to the band when a "PowerCycle" event occurs. This scenario occurs if the drive is removed from its cabinet. The drive will not honor any data read or write requests until the bands have been unlocked. This prevents the user da ta from being accessed without the appropriate credentials when the drive has been removed from its cabinet and installed in another system.
4.5 Data Bands (TBD)
When shipped from the factory, the drive is configured with a single data band called Band 0 (also known as the Global Data Ban d) which comprises LBA 0 through LBA max. The host may allocate addi tional bands (Band1 to Band15) by specifying a start LBA and a n LBA range. The real estate for this band is taken from the Global Band. Data bands cannot overlap but they can be sequential with one band ending at LBA (x) and the next beginning at LBA (x+1). Each data band has its own drive-generated encryption key. The host may change the Encryption Key (see Section 4.6 Cryptographic Erase) or the password when required.
4.6 Cryptographic Erase
A valuable feature of SEDs is the ability to perform a cryptographic erase. This involves the host telling the drive to change the data encryption key for a particular band. Once changed, the data is no longer recoverable since it was written with one key and will be read using a different key. Since the drive overwr ites the old key with the ne w one, and keeps no history of key the older key, the user data can never be recovered. This is done in a matter of seconds and is very useful if the drive is to be scrapped or repurposed.
4.7 Authenticated Firmware Download
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 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 fi le must pass the acceptance criteria for th e drive. For example it must be applicabl e to the correct drive model, and have compatible revision and customer status.
4.8 Power Requirements
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 consumpt ion. There is no additional drain on the 12V supply. See the tables in Section 2.8 Power specifications for power requirements on the standard (non-SED) drive models.
4.9 Supported Commands
The SED models support the following two commands in addition to the commands supported by the standard (non-SED) models as listed in Table 8:
- T r u s t e d S e n d
- T r u s t e d R e c e i v e
4.10 RevertSP
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 or der to execute the RevertSP method the unique PSID (Physical Sec ure ID) printed on the drive label must be provided. PSID is not electron ically accessible and can only be manually read from the drive label or scanned in via the 2D barcode.
Seagate BarraCuda Product Manual, Rev. A 28 www.seagate.com SATA Interface

5.3.2 Set Features command
This command controls the implementation of various features that the drive supports. When the drive receives this command, it sets BSY, checks the contents of the Features register, clears BSY and generates an interrupt. If the value in the register does not represent a feature that the drive supports, the command is aborted. Power-on default has the read look- ahead and write caching features enabled. The acceptable values for the Features register are defined as follows: Table 10 Set Features command 02H Enable write cache (default). 03H Set transfer mode (based on value in Sector Count register). Sector Count register values: 00H Set PIO mode to default (PIO mode 2). 01H Set PIO mode to default and disable IORDY (PIO mode 2). 08H PIO mode 0 09H PIO mode 1 0AH PIO mode 2 0BH PIO mode 3 0CH PIO mode 4 (default) 20H Multiword DMA mode 0 21H Multiword DMA mode 1 22H Multiword DMA mode 2 40H Ultra DMA mode 0 41H Ultra DMA mode 1 42H Ultra DMA mode 2 43H Ultra DMA mode 3 44H Ultra DMA mode 4 45H Ultra DMA mode 5 46H Ultra DMA mode 6 10H Enable use of SATA features 55H Disable read look-ahead (read cache) feature. 82H Disable write cache 90H Disable use of SATA features AAH Enable read look-ahead (read cache) feature (default).
