The average of the drive population tested at nominal environmental and voltage conditions. Max. The maximum value measured on any one drive over the full range of the environmental and voltage conditions. (See Section 6.
Operating modes Operating mode descriptions Operating mode Description Spin-up Start up time period from spindle stop or power down Seek Seek operation mode Write Write operation mode Read Read operation mode Idle_0 Drive ready, but not performing I/O Idle_A Spindle motor is working normally. Servo system is sleeping or waking up.
Defect flagging strategy Media defects are remapped to the next available sector during the Format Process in manufacturing. The mapping from LBA to the physical locations is calculated by an internally maintained table. Shipped format Data areas are optimally used. No extra sector is wasted as a spare throughout user data areas. All pushes generated by defects are absorbed by the spare tracks of the inner zone.
Specification Electrical interface Connector location Refer to the following illustration to see the location of the connectors.
Signal connector A Serial ATA device may be either directly connected to a host or connected to a host through a cable. For direct connection, the device plug connector is inserted directly into a backplane connector. The device plug connector and the backplane connector incorporate features that enable the direct connection to be hot pluggable and blind mateable. For connection via cable, the device signal plug connector mates with the signal cable receptacle connector on one end of the cable.

General Introduction This specification describes the host interface of HUH7210xxALx60n The interface conforms to the following working documents of Information technology with certain limitations described in the chapter 7.3 “Deviations from Standard” on page 47 - Serial ATA International Organization: Serial ATA Revision 3.2 Terminology Device Device indicates HUH7210xxALx60n Host Host indicates the system that the device is attached to.
Registers In Serial ATA, the host adapter contains a set of registers that shadow the contents of the traditional device registers, referred to as the Shadow Register Block. Shadow Register Block registers are interface registers used for delivering commands to the device or posting status from the device. About details, please refer to the Serial ATA Specification.
Cylinder Low Register This register contains the low order bits of the starting cylinder address for any disk access. At the end of the command, this register is updated to reflect the current cylinder number. In LBA Mode this register contains Bits 8-15. At the end of the command, this register is updated to reflect the current LBA Bits 8-15. The cylinder number may be from zero to the number of cylinders minus one.
Error Register Error Register 7 6 5 4 3 2 1 0 ICRCE UNC 0 IDNF 0 ABRT TK0NF AMNF Table 28 Error Register This register contains status from the last command executed by the device, or a diagnostic code. At the completion of any command except Execute Device Diagnostic, the contents of this register are valid always even if ERR=0 in the Status Register. Following a power on, a reset, or completion of an Execute Device Diagnostic command, this register contains a diagnostic code. See 9.
Status Register Status Register 7 6 5 BSY DRDY DF Table 29 4 DSC /SERV 3 2 1 0 DRQ CORR IDX ERR Status Register This register contains the device status. The contents of this register are updated whenever an error occurs and at the completion of each command. If the host reads this register when an interrupt is pending, it is considered to be the interrupt acknowledge. Any pending interrupt is cleared whenever this register is read. If BSY=1, no other bits in the register are valid.
General Operation Descriptions Reset Response There are three types of reset in ATA as follows: Power On Reset (POR) The device executes a series of electrical circuitry diagnostics. COMRESET COMRESET is issued in Serial ATA bus. The device resets the interface circuitry as well as Soft Reset. Soft Reset (Software Reset) SRST bit in the Device Control Register is set, and then is reset. The device resets the interface circuitry according to the Set Features requirement.
Register Initialization Register Default Value Diagnostic Code 01h 01h 00h 00h 00h 50h 50h Error Sector Count Sector Number Cylinder Low Cylinder High Device/Head Status Alternate Status Table 31 Default Register Values After power on, hard reset, or software reset, the register values are initialized as shown in Table 31.
Sector Addressing Mode All addressing of data sectors recorded on the device’s media is by a logical sector address. The logical CHS address for HUH7210xxALx60n is different from the actual physical CHS location of the data sector on the disk media. All addressing of data sectors recorded on the device’s media. HUH7210xxALx60n support both Logical CHS Addressing Mode and LBA Addressing Mode as the sector addressing mode.
Power Management Feature The power management feature set allows an application client to modify the behavior of a device in a manner that reduces the power required to operate. The power management feature set provides a set of commands and a timer that enables a device to implement low power consumption modes. The Power Management feature set implements the following set of functions. 1. A Standby timer 2. Idle command 3. Idle Immediate command 4. Sleep command 5. Standby command 6.
Power Management Commands The Check Power Mode command allows a host to determine if a device is in, going, to or leaving standby or idle mode. The Idle and Idle Immediate commands move a device to idle mode immediately from the active or standby modes. The idle command also sets the standby timer count and enables or disables the standby timer. The Standby and Standby Immediate commands move a device to standby mode immediately from the active or idle modes.
SMART Function The intent of Self-monitoring, analysis and reporting technology (SMART) is to protect user data and prevent unscheduled system downtime that may be caused by predictable degradation and/or fault of the device. By monitoring and storing critical performance and calibration parameters, SMART devices employ sophisticated data analysis algorithms to predict the likelihood of near-term degradation or fault condition.
Error Log Logging of reported errors is supported. The device provides information on the last five errors that the device reported as described in SMART error log sector. The device may also provide additional vendor specific information on these reported errors. The error log is not disabled when SMART is disabled. Disabling SMART shall disable the delivering of error log information via the SMART READ LOG SECTOR command.
Security Mode Feature Set Security Mode Feature Set is a powerful security feature. With a device lock password, a user can prevent unauthorized access to hard disk device even if the device is removed from the computer. The following commands are supported for this feature.
Operation example Master Password setting The system manufacturer/dealer can set a new Master Password from default Master Password using the 2 Set Password command, without enabling the Device Lock Function. The Master Password Revision Code is set to FFFEh as shipping default by the HDD manufacturer User Password setting When a User Password is set, the device will automatically enter lock mode the next time the device is powered on. < Setting Password > (ref.
Operation from POR after User Password is set When Device Lock Function is enabled, the device rejects media access command until a Security Unlock command is successfully completed.
User Password Lost If the User Password is forgotten and High level security is set, the system user can’t access any data. However, the device can be unlocked using the Master Password. If a system user forgets the User Password and Maximum security level is set, data access is impossible. However, the device can be unlocked using the Security Erase Unit command to unlock the device and erase all user data with the Master Password.

Host Protected Area Feature Host Protected Area Feature is to provide the ‘protected area’ which cannot be accessed via conventional method. This ‘protected area’ is used to contain critical system data such as BIOS or system management information. The contents of entire system main memory may also be dumped into ‘protected area’ to resume after system power off. The LBA/CYL changed by following command affects the Identify Device Information. The following set of commands is implemented for this function.
4. Advanced usage using protected area The data in the protected area is accessed by following. Issue Read Native Max Address command to get the real device maximum LBA. Returned value shows that native device Maximum LBA is 12,692,735 (C1ACFFh) regardless of the current setting. Make entire device be accessible including the protected area by setting device Maximum LBA as 12,692,735 (C1ACFFh) via Set Max Address command with volatile option.
Write Cache Function Write cache is a performance enhancement whereby the device reports as completing the write command (Write Sector(s), Write Multiple and Write DMA) to the host as soon as the device has received all of the data into its buffer. And the device assumes responsibility to write the data subsequently onto the disk. While writing data after completed acknowledgment of a write command, soft reset or hard reset does not affect its operation.
Power-up in Standby feature set Power-Up In Standby feature set allows devices to be powered-up into the Standby power management state to minimize inrush current at power-up and to allow the host to sequence the spin-up of devices. This feature set will be enabled/disabled via the SET FEATURES command. The enabling of this feature set shall be persistent after power cycle. A device needs a SET FEATURES subcommand to spin-up to active state when the device has powered-up into Standby.
Streaming feature Set The Streaming feature set is an optional feature set that allows a host to request delivery of data from a contiguous logical block address range within an allotted time. This places a priority on time to access the data rather than the integrity of the data. Streaming feature set commands only support 48-bit addressing.
Not Sequential bit The Not Sequential bit specifies that the next read stream command with the same Stream ID may not be sequential in LBA space. This information helps the device with pre-fetching decisions. Read Continuous bit If the Read Continuous bit is set to one for the command, the device shall transfer the requested amount of data to the host within the Command Completion Time Limit even if an error occurs. The data sent to the host by the device in an error condition is vendor specific.
SATA BIST (Built-in Self Test) The device supports the following BIST modes, and begins operations when it receives BIST Activate FIS. F – Far End Analog Loopback.
SATA Interface Power Management The device supports both receiving host-initiated interface power management requests and initiating interface power management. The device initiates interface power management when the device enters its power saving mode whose power consumption is lower than Idle mode. Low PHY power conditions overview Low PHY power conditions are PHY conditions where the PHY is in a reduced power state (e.g., has disabled circuitry in order to reduce power).
Software Setting Preservation When a device is enumerated, software will configure the device using SET FEATURES and other commands. These software settings are often preserved across software reset but not necessarily across hardware reset. In Parallel ATA, only commanded hardware resets can occur, thus legacy software only reprograms settings that are cleared for the particular type of reset it has issued.
Serial ATA Optional Features There are several optional features defined in Serial ATA Revision 3.2. The following shows whether these features are supported or not. Asynchronous Signal Recovery The device supports asynchronous signal recovery defined in Serial ATA Revision 3.2. Device Power Connector Pin 11 Definition Serial ATA Revision 3.
Counter Identifiers Each counter begins with a 16-bit identifier. Table 37 defines the counter value for each identifier. Any unused counter slots in the log page should have a counter identifier value of 0h. Optional counters that are not implemented shall not be returned in log page 11h. A value of ‘0’ returned for a counter means that there have been no instances of that particular event.
Counter Definitions The counter definitions in this section specify the events that a particular counter identifier represents. Identifier 000h There is no counter associated with identifier 000h. A counter identifier of 000h indicates that there are no additional counters in the log page. Identifier 001h The counter with identifier 001h returns the number of commands that returned an ending status with the ERR bit set to one in the Status register and the ICRC bit set to one in the Error register.
Identifier 00Ah The counter with identifier 00Ah returns the number of transmitted Device-to-Host Register FISes with the device reset signature in response to a COMRESET, which were successfully followed by an R_OK from the host. Identifier 00Bh The counter with identifier 00Bh returns the number of received Host-to-Device FISes of all types (Data and nonData) to which the device responded with R_ERRP due to CRC error.
READ LOG EXT Log Page 11h READ LOG EXT log page 11h is one page (512 bytes) in length. The first Dword of the log page contains information that applies to the rest of the log page. Software should continue to process counters until a counter identifier with value 0h is found or the entire page has been read. A counter identifier with value 0h indicates that the log page contains no more counter values past that point. Log page 11h is defined in Table 38.
NCQ NON-DATA (63h) The NCQ NON-DATA feature allows the host to manage the outstanding NCQ commands and/or affect the processing of NCQ commands. The NCQ NON-DATA command is a non-data NCQ command. Only specified NCQ NON-DATA subcommands are executed as Immediate NCQ commands. NCQ NON-DATA cmd, LBA fields should not be set to reserved. LBA fields are optionally used in SetFeatures cmd.
Abort NCQ Queue Subcommand (0h) A Subcommand set to 0h specifies the Abort NCQ Queue subcommand (see 11.15.1 Abort NCQ Queue Subcommand (0h)). The Abort NCQ Queue subcommand is an immediate NCQ command. Support for this subcommand is indicated in the NCQ NON-DATA log (see 9.17.4.3 Read Log Ext Log Page 12h) The Abort NCQ Queue subcommand affects only those NCQ commands for which the device has indicated command acceptance before accepting this NCQ NON-DATA command.
READ LOG EXT Log Page 12h To determine the supported NCQ NON-DATA subcommands and their respective features, host software reads log address 12h. This log is supported if the NCQ NON-DATA command is supported (i.e., IDENTIFY DEVICE word 77 bit 5 is set to one). Table 41 defines the 512 bytes that make up the SATA NCQ NON-DATA log. The value of the General Purpose Logging Version word is 0001h.
Supports the Abort Selected TTAG If Supports Abort Selected TTAG is set to one, then the device supports the value of Abort Selected for the Abort Type parameter of the Abort NCQ Queue command. If Supports Abort Selected TTAG is cleared to zero, then the device does not support the value of Abort Selected for the Abort Type parameter of the Abort NCQ Queue command.
Rebuild Assist The Rebuild Assist mode provides a method for a host controlling the rebuild process to determine that logical sectors on the failed device are unreadable without having to read every LBA to determine the unreadable logical sectors (i.e., the read command is terminated with an error and the failed LBA is reported in the sense data). The storage array controller then may reconstruct the failed logical sectors. The remaining logical sectors may be copied to the replacement device.
Disabled Physical Elements The Disabled Physical Elements field specifies if physical elements shall be disabled. Each bit that is set to one in the Disabled Physical Elements field specifies that LBAs associated with this physical element shall respond to read commands and write commands as if the associated LBAs have predicted errors.
SCT Command Transport feature Set Overview Introduction SMART Command Transport (SCT) is the method for the drive to receive commands using log page E0h and transporting data using log page E1h. These log pages are used as follows: Write log page Read log page Table 43 Log page E0h Issue Command Return Status Log Page E1h Send Data to the drive Received Data from the drive SCT Log Page and direction There are two ways to access the log pages: using SMART READ/WRITE LOG and READ/WRITE LOG EXT.
Resets If an SCT command is executing, any reset including Soft Reset, Hard Reset, COMRESET, and Power-On Reset all cause the command to be terminated. This could result in partial command execution or data loss. There is no indication once the drive becomes ready that the previous command was terminated.
SCT Command Protocol Command Transport SCT Command Transport occurs when a 512-byte data packet (called “Key Sector”) is created and the written to SMART or extended log page E0h. The key sector specifies Action and Function Codes along with the parameters that are required to perform the action.

The number of sectors requested to transfer (Sector Count register) in the read or write log command is larger than required by SCT command.
Data transfer Once an SCT command has been issued, status can be checked and data can be transferred. Data transfer uses log page E1h.
SCT Status Request Once an SCT command has been issued, a status is reported in the ATA registers. This status indicates that the command was accepted or that an error occurred. This ATA status return does not indicate successful completion of the SCT actions. Some commands can take several minutes or even hours to execute. In this case, the host can determine execution progress by requesting SCT status. Log page E0h contains the status information. Reading log page E0h retrieves the status information.

These are one byte 2’s complement numbers, which allow a range from 127°C to +127°C to be specified. A value of 80h indicates an initial value or a discontinuity in temperature recording. The Actual time between samples may vary because commands may not be interrupted. The sampling period is the minimum time between samples. See Note 1.
Extended Power Conditions (EPC) feature The Extended Power Conditions feature set provides a host with additional methods to control the power condition of a device. Subcommand code 4Ah enables, disables, and configures the use of the Extended Power Conditions feature set. If the EPC feature set is not supported, then the device return command aborted Table 71 describes the EPC subcommands and Table 72 describes the power condition IDs.
Power condition timers The device has manufacturer specified power-on default settings for the power condition timers. Power condition timers are changeable with the SET FEATURES Extended Power Conditions subcommand. A power condition timer set to zero indicates that the associated power condition is disabled. If the power condition is enabled, then the value of each timer specifies the time after command completion that the device waits before transitioning to the power condition.
Sanitize Device feature set Overview The Sanitize Device feature set allows hosts to request that devices modify the content of all user data areas in the device using sanitize operations. Sanitize operations use one of the operations defined in this sub clause to make all previously written content in the user data area of the device unable to be read. Sanitize operations affect the following: a) user data areas b) user data areas that are not currently allocated (e.g.
B) 30h; or C) 10h; g) READ LOG DMA EXT command requesting one of the following log addresses: A) E0h; B) 30h; or C) 10h; h) SMART RETURN STATUS command; or i) SET FEATURES PUIS feature set device spin-up subcommand. If a sanitize operation is interrupted by a power-on reset, the sanitize operation continues.
Sanitize Device state machine Figure 12 describes the operation of the Sanitize Device state machine. SD0: Sanitize Idle State In SD0: Sanitize Idle state the Sanitize Device state machine is ready for a sanitize operation command or a SANITIZE FREEZE LOCK EXT command. This state is entered when the device processes a power-on reset while in the SD1: Sanitize Freeze Lock state or the SD4: Sanitize Operation Succeeded state.
SD1: Sanitize Frozen State In SD1: Sanitize Frozen state, the device will abort Sanitize operation commands. While in this state, Sanitize Device state machine does not change state if the device processes a SANITIZE STATUS EXT command. Transition SD1:SD0: If the device processes a hardware reset or a power-on reset, then the device transitions to the SD0: Sanitize Idle state. SD2: Sanitize Operation State In the SD2: Sanitize Operation state, the device is processing a sanitize operation.
Trusted Computing Group feature set This chapter provides information on Western Digital encryption-specific HDD firmware and features. assumed that the reader is familiar with the referenced specifications and industry standards. It is Referenced Specifications and Standards TCG Specifications This section references 3 separate TCG specifications, which are available on the TCG website: (http://www.trustedcomputinggroup.org/): 1. TCG Core Specification, Version 2.00, Revision 1.

Encryption Algorithms Advanced Encryption Standard (AES) Support AES encryption is implemented in hardware, with support for ECB or XTS mode for 128 bit or 256 bit keys. A single key is active at any one time within the AES hardware engine. Firmware is responsible for reading the keys from the hardware and also for determining which key is attached to a given LBA range; the hardware can only detect if the LBA has been encrypted or not.
Key Wrap The NIST SP800-38F key wrap algorithm is used to encrypt a key with another key (KEK= Key Encryption Key). For any band i, the KEK_i is derived from PIN_i and salt_i using the NIST 800-132 algorithm. The KEK_i is then used to wrap a band’s encryption key. Key Erasure Cryptographic erase procedure Erase and overwrite wrapped key material with 0x00. Erase and store the new wrapped key material.
K_AES_256 Table The K_AES_256 table has 16 rows, one row for each band that can be allocated by the user. The first row is for the “global range”, also known as Band 0. This table was implemented without the “Name”, “Common Name”, and “Key” Columns. UID (8 byte hex) MODE 00 00 08 06 00 00 00 01 23 00 00 08 06 00 00 00 02 23 .. .. 00 00 08 06 00 00 00 10 23 Table 75 Western Digital Implementation of K_AES_256 Table The mode is specified in the TCG Enterprise SSC as a “Vendor Unique” (VU) entry.
‘Locking Info’ Table As specified in the TCG Enterprise SSC, this table has only 1 row. The “Vendor Unique” entries are specified in the table below. Encryption Support is initialized to Encryption Support=23 (media encryption mode) in manufacturing. NAME Version Encrypt Support Max Ranges Max ReEncryptions Keys Available Cfg 0 0 23 6 0 0 Table 77 Western Digital Implementation of ‘Locking Info’ Table ‘Locking SP’ Locking Table The “Vendor Unique” (VU) values for this table are shown below.
Firmware Download and Signing The Western Digital firmware signing and download for encryption drives is meant to provide a mechanism for secure updates through the Host interface. Firmware is downloaded to the drive through the host interface, and the signature is verified using a public key installed in the reserved area during manufacturing, before it is loaded to RAM or installed in the reserved area on the HDD.

MSID The MSID is set for each drive at the time of manufacturing to the serial number concatenated 4 times, to create a 32 byte password. Thus, as an example, if the serial number of a drive is abcd1234, the MSID would then be set to abcd1234abcd1234abcd1234abcd1234. In TCG use cases such as “erase” or “repurpose”, this will be the MSID that is restored to the drive.

TCG Enterprise SSC Commands The table below describes how the required TCG Enterprise SSC commands behave on encryption drives in the locked and unlocked states. The TCG Enterprise requires the implementation of the Base, Admin, Locking, and Crypto Templates. Command Description unlocked Locked Session Management There are two types of sessions: 1) Read-Only session. 2) Read-Write session. The SSC requires us to support Read-Write sessions. Read-Only session is not allowed.
Command Description Base Template Mandatory Set Sets a value in a table Get ParamCheck LRC Next Authenticate GetACL unlocked Locked N/A - table operations. N/A - table operations. Not related to Not related to bands/data on drive. bands/data on drive. Gets (reads) a value in a table N/A - table operations. N/A - table operations. Not related to Not related to bands/data on drive. bands/data on drive.
Error Codes All error codes are compliant with the TCG Core specification and SIIF, except in the following case: The maximum sessions allowed at any single time is 1. When a session is active and a new session is requested, the drive answers the host with SP_BUSY, instead of NO_SESSIONS_AVAILABLE. Life Cycle model A Life Cycle model for TCG is able to combine TCG and BDE (with ATA security feature) features in a single code and to switch back and forth between TCG and BDE modes.
Command Protocol The commands are grouped into different classes according to the protocols followed for command execution. The command classes with their associated protocols are defined below. Please refer to Serial ATA Revision 3.2 about each protocol. For all commands, the host must first check if BSY=1, and should proceed no further unless and until BSY=0. For all commands, the host must also wait for RDY=1 before proceeding.
Write Multiple Write Multiple Ext Write Multiple FUA Ext Write Sector(s) Write Sector(s) Ext Write Stream Ext Execution includes the transfer of one or more 512 byte sectors of data from the host to the device.

SMART Subcommand In order to select a subcommand the host must write the subcommand code to the device’s Features Register before issuing the SMART Function Set command. The subcommands and their respective codes are listed below.
SMART Save Attribute Values (Subcommand D3h) This subcommand causes the device to immediately save any updated Attribute Values to the device’s Attribute Data sector regardless of the state of the Attribute Autosave feature. Upon receipt of the SMART Save Attribute Values subcommand from the host, the device writes any updated Attribute Values to the Attribute Data sector.
SMART Read Log Sector (Subcommand D5h) This command returns the specified log sector contents to the host. The 512 bytes data are returned at a command and the Sector Count value shall be set to one. The Sector Number shall be set to specify the log sector address.
SMART Return Status (Subcommand DAh) This command is used to communicate the reliability status of the device to the host’s request. Upon receipt of the SMART Return Status subcommand the device saves any updated Pre-failure type Attribute Values to the reserved sector and compares the updated Attribute Values to the Attribute Thresholds. If the device does not detect a Threshold Exceeded Condition, the device loads 4Fh into the Cylinder Low register, C2h into the Cylinder High register.
Device Attributes Data Structure The following defines the 512 bytes that make up the Attribute Value information. This data structure is accessed by the host in its entirety using the SMART Read Attribute Values subcommand.
