3 Fixed disk subsystem description

3.1 Control Electronics

The drive is electronically controlled by a microprocessor, several logic modules, digital/analog modules, and various drivers and receivers. The control electronics performs the following major functions:

Controls and interprets all interface signals between the host controller and the drive. Controls read write accessing of the disk media, including defect management and error recovery. Controls starting, stopping, and monitoring of the spindle. Conducts a power-up sequence and calibrates the servo. Analyzes servo signals to provide closed loop control. These include position error signal and estimated

velocity.

Monitors the actuator position and determines the target track for a seek operation. Controls the voice coil motor driver to align the actuator in a desired position. Constantly monitors error conditions of the servo and takes corresponding action if an error occurs. Monitors various timers such as head settle and servo failure. Performs self-checkout (diagnostics).

3.2 Head disk assembly

The head disk assembly (HDA) is assembled in a clean room environment and contains the disks and actuator assembly. Air is constantly circulated and filtered when the drive is operational. Venting of the HDA is accomplished via a breather filter.

The spindle is driven directly by an in-hub, brushless, sensorless DC drive motor. Dynamic braking is used to quickly stop the spindle.

3.3 Actuator

The read/write heads are mounted in the actuator. The actuator is a swing-arm assembly driven by a voice coil motor. A closed-loop positioning servo controls the movement of the actuator. An embedded servo pattern supplies feedback to the positioning servo to keep the read/write heads centered over the desired track.

The actuator assembly is balanced to allow vertical or horizontal mounting without adjustment. When the drive is powered off, the actuator automatically moves the head to the actuator ramp outside of the disk

where it parks.

- Seek time

- Latency

 Data transfer speed  Buffering operation (Look ahead/Write cache)

All the above parameters contribute to drive performance. There are other parameters that contribute to the performance of the actual system. This specification defines the characteristics of the drive, not the characteristics of the system throughput which depends on the system and the application.

Table 9 Mechanical positioning performance

The terms “Typical” and “Max” are used throughout this specification with the following meanings:

Typical. 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 6.2, “Environment” on page 28 and Section 6.3, “DC Power Requirements” on page 30.)

Seek time is measured from the start of the motion of the actuator to the start of a reliable read or write operation. "Reliable read or write" implies that error correction/recovery is not used to correct arrival problems. The average seek time is measured as the weighted average of all possible seek combinations.

N N+1 N+2 N+3

defect defect

skip

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.

Figure 1 PList physical format

Defects are skipped without any constraint, such as track or cylinder boundary. The calculation from LBA to physical is done automatically by internal table.

6.3.3 Power supply generated ripple at drive power connector

Table 20 Power supply generated ripple at drive power connector

During drive start up and seeking 12-volt ripple is generated by the drive (referred to as dynamic loading). If the power of several drives is daisy chained together, the power supply ripple plus the dynamic loading of the other drives must remain within the above regulation tolerance. A common supply with separate power leads to each drive is a more desirable method of power distribution.

To prevent external electrical noise from interfering with the performance of the drive, the drive must be held by four screws in a user system frame which has no electrical level difference at the four screws position and has less than ±300 millivolts peak to peak level difference to the ground of the drive power connector.

6.4 Reliability

6.4.1 Data integrity

No more than one sector is lost at Power loss condition during the write operation when the write cache option is disabled. If the write cache option is active, the data in write cache will be lost. To prevent the loss of customer data, it is recommended that the last write access before power off be issued after setting the write cache off.

6.4.2 Cable noise interference

To avoid any degradation of performance throughput or error rate when the interface cable is routed on top or comes in contact with the HDA assembly, the drive must be grounded electrically to the system frame by four screws. The common mode noise or voltage level difference between the system frame and power cable ground or AT interface cable ground should be in the allowable level specified in the power requirement section.

6.4.3 Load/Unload

The product supports a minimum of 300,000 normal load/unloads in a 40° C environment. Load/unload is invoked by transition of the HDD's power mode.

Idle <-> unload idle Idle <-> Low rpm idle*

*Note: Low rpm idle mode is supported on specific drive PN, only.

6.4.4 Start/stop cycles

The drive withstands a minimum of 50,000 start/stop cycles in a 40° C environment and a minimum of 10,000 start/stop cycles in extreme temperature or humidity within the operating range. .

6.4.5 Preventive maintenance

Hitachi hard disk drive specifications

6.4.7 Required Power-Off Sequence

The required BIOS sequence for removing power from the drive is as follows:

Step 1: Issue one of the following commands. Standby Standby immediate Sleep

Note: Do not use the Flush Cache command for the power off sequence because this command does not invoke Unload

Step 2: Wait until the Command Complete status is returned. In a typical case 350 ms are required for the

command to finish completion; however, the BIOS time out value needs to be 30 seconds considering error

recovery time.

Step 3: Terminate power to HDD.

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.

In the following cases, the host adapter sets the BSY bit in its shadow Status Register and transmits a FIS to the device containing the new contents.

 Command register is written in the Shadow Register Block  Device Control register is written in the Shadow Register Block with a change of state of the SRST bit  COMRESET is requested

8.1 Alternate Status Register

Table 27 Alternate Status Register

This register contains the same information as the Status Register. The only difference is that reading this register does not imply interrupt acknowledge or clear a pending interrupt. See 8.13 "Status Register" on the page 53 for the definition of the bits in this register.

8.2 Command register

This register contains the command code being sent to the device. Command execution begins immediately after this register is written. The command set is shown in Table 66 Command Set on page 103.

All other registers required for the command must be set up before writing the Command Register.

8.3 Cylinder High Register

This register contains the high 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 16-23. At the end of the command, this register is updated to reflect the current LBA Bits 16-23.

Busy. BSY=1 whenever the device is accessing the registers. The host should not read or write any registers when BSY=1. If the host reads any register when BSY=1, the contents of the Status Register will be returned.

DRDY (RDY)

Device Ready. RDY=1 indicates that the device is capable of responding to a command. RDY will be set to 0 during power on until the device is ready to accept a command. If the device detects an error while processing a command, RDY is set to 0 until the Status Register is read by the host, at which time RDY is set back to 1.

Device Fault. This product does not support DF bit. DF bit is always zero.

DSC

Device Seek Complete. DSC=1 indicates that a seek has completed and the device head is settled over a track. DSC is set to 0 by the device just before a seek begins. When an error occurs, this bit is not changed until the Status Register is read by the host, at which time the bit again indicates the current seek complete status.

When the device enters into or is in Standby mode or Sleep mode, this bit is set by device in spite of not spinning up.

SERV (SRV)

Service. This product does not support SERV bit.

DRQ

Data Request. DRQ=1 indicates that the device is ready to transfer a word or byte of data between the host and the device. The host should not write the Command register when DRQ=1.

CORR (COR)

Corrected Data. Always 0.

IDX

Index. IDX=1 once per revolution. Since IDX=1 only for a very short time during each revolution, the host may not see it set to 1 even if the host is reading the Status Register continuously. Therefore, the host should not attempt to use IDX for timing purposes.

ERR

Error. ERR=1 indicates that an error occurred during execution of the previous command. The Error Register should be read to determine the error type. The device sets ERR=0 when the next command is received from the host.

Table 32 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.

All addressing of data sectors recorded on the device's media is by a logical sector address. The logical CHS address for HDS7210xxCLA3yz / HUA7220xxCLA33z / HCS5C10xxCLA382 / HCS7210xxCLA3y2 /

HDS5C10xxCLA382 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.

HDS7210xxCLA3yz / HUA7220xxCLA33z / HCS5C10xxCLA382 / HCS7210xxCLA3y2 /

HDS5C10xxCLA382 support both Logical CHS Addressing Mode and LBA Addressing Mode as the sector

addressing mode.

The host system may select either the currently selected CHS translation addressing or LBA addressing on a command-by-command basis by using the L bit in the DEVICE/HEAD register. So a host system must set the L bit to 1 if the host uses LBA Addressing mode.

9.3.1 Logical CHS Addressing Mode

The logical CHS addressing is made up of three fields: the cylinder number, the head number and the sector number. Sectors are numbered from 1 to the maximum value allowed by the current CHS translation mode but can not exceed 255(0FFh). Heads are numbered from 0 to the maximum value allowed by the current CHS translation mode but can not exceed 15(0Fh). Cylinders are numbered from 0 to the maximum value allowed by the current CHS translation mode but cannot exceed 65535(0FFFFh).

When the host selects a CHS translation mode using the INITIALIZE DEVICE PARAMETERS command, the host requests the number of sectors per logical track and the number of heads per logical cylinder. The device then computes the number of logical cylinders available in requested mode.

The default CHS translation mode is described in the Identify Device Information. The current CHS translation mode also is described in the Identify Device Information.

9.3.2 LBA Addressing Mode

Logical sectors on the device shall be linearly mapped with the first LBA addressed sector (sector 0) being the same sector as the first logical CHS addressed sector (cylinder 0, head 0, sector 1). Irrespective of the logical CHS translation mode currently in effect, the LBA address of a given logical sector does not change. The following is always true:

LBA = ( (cylinder * heads_per_cylinder + heads) * sectors_per_track ) + sector - 1

where heads_per_cylinder and sectors_per_track are the current translation mode values.

On LBA addressing mode, the LBA value is set to the following register.

9.4 Power Management Feature

The power management feature set permits a host to modify the behavior in a manner which 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.

HDS7210xxCLA3yz / HUA7220xxCLA33z / HCS5C10xxCLA382 / HCS7210xxCLA3y2 / HDS5C10xxCLA382 implement the following set of functions.

1. A Standby timer

2. Idle command

3. Idle Immediate command

4. Sleep command

5. Standby command

6. Standby Immediate command

9.4.1 Power Mode

The lowest power consumption when the device is powered on occurs in Sleep Mode. When in sleep mode, the device requires a reset to be activated.

In Standby Mode the device interface is capable of accepting commands, but as the media may not immediately accessible, there is a delay while waiting for the spindle to reach operating speed.

In Idle Mode the device is capable of responding immediately to media access requests. In Active Mode the device is under executing a command or accessing the disk media with read look-ahead

function or writes cache function.

9.4.2 Power Management Commands

The Check Power Mode command allows a host to determine if a device is currently in, going to or leaving standby 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 starts the standby timer.

The Standby and Standby Immediate commands move a device to standby mode immediately from the active or idle modes. The standby command also sets the standby timer count.

The Sleep command moves a device to sleep mode. The device's interface becomes inactive at the completion of the sleep command. A reset is required to move a device out of sleep mode. When a device exits sleep mode it will enter Standby mode.

9.4.3 Standby timer

The standby timer provides a method for the device to automatically enter standby mode from either active or idle mode following a host programmed period of inactivity. If the device is in the active or idle mode, the device waits for the specified time period and if no command is received, the device automatically enters the standby mode.

If the value of SECTOR COUNT register on Idle command or Standby command is set to 00h, the standby timer is disabled.

9.5 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. By alerting the host system of a negative reliability status condition, the host system can warn the user of the impending risk of a data loss and advise the user of appropriate action.

9.5.1 Attributes

Attributes are the specific performance or calibration parameters that are used in analyzing the status of the device. Attributes are selected by the device manufacturer based on that attribute's ability to contribute to the prediction of degrading or faulty conditions for that particular device. The specific set of attributes being used and the identity of these attributes is vendor specific and proprietary.

9.5.2 Attribute values

Attribute values are used to represent the relative reliability of individual performance or calibration attributes. The valid range of attribute values is from 1 to 253 decimal. Higher attribute values indicate that the analysis algorithms being used by the device are predicting a lower probability of a degrading or faulty condition existing. Accordingly, lower attribute values indicate that the analysis algorithms being used by the device are predicting a higher probability of a degrading or faulty condition existing.

9.5.3 Attribute thresholds

Each attribute value has a corresponding attribute threshold limit which is used for direct comparison to the attribute value to indicate the existence of a degrading or faulty condition. The numerical values of the attribute thresholds are determined by the device manufacturer through design and reliability testing and analysis. Each attribute threshold represents the lowest limit to which its corresponding attribute value can be equal while still retaining a positive reliability status. Attribute thresholds are set at the device manufacturer's factory and cannot be changed in the field. The valid range for attribute thresholds is from 1 through 253 decimal.

9.5.4 Threshold exceeded condition

If one or more attribute values, whose Pre-failure bit of their status flag is set, are less than or equal to their corresponding attribute thresholds, then the device reliability status is negative, indicating an impending degrading or faulty condition.

9.5.5 SMART commands

The SMART commands provide access to attribute values, attribute thresholds and other logging and reporting information.

Hitachi hard disk drive specifications

9.5.6 Off-line Read Scanning

The device provides the off-line read scanning feature with reallocation. This is the extension of the off-line data collection capability. The device performs the entire read scan with reallocation for the marginal sectors to prevent the user data lost.

If interrupted by the host during the read scanning, the device services the host command.

9.5.7 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.

If a device receives a firmware modification, all error log data is discarded and the device error count for the life of the device is reset to zero.

9.5.8 Self-test

The device provides the self-test features which are initiated by SMART Execute Off-line Immediate command. The self-test checks the fault of the device, reports the test status in Device Attributes Data and stores the test result in the SMART self-test log sector as described in SMART self-test log data structure. All SMART attributes are updated accordingly during the execution of self-test.

If interrupted by the host during the self-tests, the device services the host command. If the device receives a firmware modification, all self-test log data is discarded.

9.6.4.5 Attempt limit for SECURITY UNLOCK command

The SECURITY UNLOCK command has an attempt limit. The purpose of this attempt limit is to prevent that someone attempts to unlock the drive by using various passwords many times.

The device counts the password mismatch. If the password does not match, the device counts it up without distinguishing the Master password and the User password. If the count reaches 5, EXPIRE bit (bit 4) of Word 128 in Identify Device information is set, and then SECURITY ERASE UNIT command and SECURITY UNLOCK command are aborted until a hard reset or a power off. The count and EXPIRE bit are cleared after a power on reset or a hard reset.

Host Protected Area Feature is to provide the 'protected area' which can not 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.

9.7.1 Example for operation (In LBA mode)

Assumptions: For better understanding, the following example uses actual values for LBA, size, etc. Since it is just an example,

these values could be different.

Device characteristics

1. Shipping HDDs from HDD manufacturer

When the HDDs are shipped from HDD manufacturer, the device has been tested to have usable capacity of 6.4GB besides flagged media defects not to be visible by system.

2. Preparing HDDs at system manufacturer Special utility software is required to define the size of protected area and store the data into it.

The sequence is:

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. The option could be either nonvolatile or volatile.

Test the sectors for protected area (LBA >= 12,289,536 (BB8600h)) if required.

Hitachi hard disk drive specifications

Write information data such as BIOS code within the protected area. Change maximum LBA using Set Max Address command to 12,289,535 (BB85FFh) with nonvolatile

option.

From this point, the protected area cannot be accessed till next Set Max Address command is issued.

Any BIOSes, device drivers, or application software access the HDD as if that is the 6.2GB device because the device acts exactly the same as real 6.2GB device does.

3. Conventional usage without system software support

Since the HDD works as 6.2GB device, there is no special care to use this device for normal use.

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. By using this option, unexpected power removal or reset will not make the protected area remained accessible.

Read information data from protected area.

Issue hard reset or POR to inhibit any access to the protected area.

9.7.2 Security extensions

1. Set Max Set Password

2. Set Max Lock

3. Set Max Freeze Lock

4. Set Max Unlock.

The Set Max Set Password command allows the host to define the password to be used during the current power on cycle. The password does not persist over a power cycle but does persist over a hardware or software reset. This password is not related to the password used for the Security Mode Feature set. When the password is set the device is in the Set_Max_Unlocked mode. The Set Max Lock command allows the host to disable the Set Max commands (except set Max Unlock) until the next power cycle or the issuance and acceptance of the Set Max Unlock command. When this command is accepted the device is in the Set_Max_Locked mode. The Set Max Unlock command changes the device from the Set_Max_Locked mode to the Set_Max_Unlocked mode. The Set Max Freeze Lock command allows the host to disable the Set Max commands (including Set Max UNLOCK) until the next power cycle. When this command is accepted the device is in the Set_Max_Frozen mode.

The IDENTIFY DEVICE response word 83, bit 8 indicates that this extension is supported if set, and word 86, bit 8 indicate the Set Max security extension enabled if set.

Hitachi hard disk drive specifications

9.8 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. But power off terminates writing operation immediately and unwritten data are to be lost.

 Soft reset, Standby (Immediate) command and Flush Cache commands during writing the cached data are

executed after the completion of writing to media. So the host system can confirm the completion of write cache operation by issuing Soft reset, Standby (Immediate) command or Flush Cache command to the device before power off.

Hitachi hard disk drive specifications

9.9 Reassign Function

The reassign Function is used with read commands and write commands. The sectors of data for reassignment are prepared as the spare data sector.

This reassignment information is registered internally, and the information is available right after completing the reassign function. Also the information is used on the next power on reset or hard reset.

If the number of the spare sector reaches 0 sectors, the reassign function will be disabled automatically. The spare tracks for reassignment are located at regular intervals from Cylinder 0. As a result of reassignment,

the physical location of logically sequenced sectors will be dispersed.

9.9.1 Auto Reassign Function

The sectors those show some errors may be reallocated automatically when specific conditions are met. The spare tracks for reallocation are located at regular intervals from Cylinder 0. The conditions for auto-reallocation are described below.

Non recovered write errors

When a write operation can not be completed after the Error Recovery Procedure (ERP) is fully carried out, the sector(s) are reallocated to the spare location. An error is reported to the host system only when the write cache is disabled and the auto reallocation is failed.

If the write cache function is ENABLED, and when the number of available spare sectors reaches 0 sectors, both auto reassign function and write cache function are disabled automatically.

Non recovered read errors When a read operation is failed after defined ERP is fully carried out, a hard error is reported to the host system.

This location is registered internally as a candidate for the reallocation. When a registered location is specified as a target of a write operation, a sequence of media verification is performed automatically. When the result of this verification meets the criteria, this sector is reallocated.

Recovered read errors When a read operation for a sector failed once then recovered at the specific ERP step, this sector of data is

reallocated automatically. A media verification sequence may be run prior to the relocation according to the pre-defined conditions.

Hitachi hard disk drive specifications

9.10 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. The device remains in Standby until the SET FEATURES subcommand is received.

If power-up into Standby is enabled, when an IDENTIFY DEVICE is received while the device is in Standby as a result of powering up into Standby, the device shall set word 0 bit 2 to one to indicate that the response is incomplete, then only words 0 and 2 are correctly reported.

The IDENTIFY DEVICE information indicates the states as follows:

 identify device information is complete or incomplete  this feature set is implemented  this feature set is enabled or disabled  the device needs the Set Features command to spin-up into active state

9.11 Advanced Power Management feature set (APM)

This feature allows the host to select an advanced power management level. The advanced power management level is a scale from the lowest power consumption setting of 01h to the maximum performance level of FEh. Device performance may increase with increasing advanced power management levels. Device power consumption may increase with increasing advanced power management levels. The advanced power management levels contain discrete bands, described in the section of Set Feature command in detail. This feature set uses the following functions:

1. A SET FEATURES subcommand to enable Advanced Power Management

2. A SET FEATURES subcommand to disable Advanced Power Management

Advanced Power Management is independent of the Standby timer setting. If both Advanced Power Management and the Standby timer are set, the device will go to the Standby state when the timer times out or the device‟s Advanced Power Management algorithm indicates that the Standby state should be entered.

The IDENTIFY DEVICE response word 83, bit 3 indicates that Advanced Power Management feature is supported if set. Word 86, bit 3 indicates that Advanced Power Management is enabled if set. Word 91, bits 7-0 contain the current Advanced Power Management level if Advanced Power Management is enabled.

Hitachi hard disk drive specifications

9.12 48-bit Address Feature Set

The 48-bit Address feature set allows devices with capacities up to 281,474,976,710,655 sectors. This allows device capacity up to 144,115,188,075,855,360 bytes. In addition, the number of sectors that may be transferred by a single command are increased by increasing the allowable sector count to 16 bits.

Commands unique to the 48-bit Address feature set are:

 Flush Cache Ext  Read DMA Ext  Read FPDMA Queued  Read Multiple Ext  Read Native Max Address Ext  Read Sector(s) Ext  Read Verify Sector(s) Ext  Set Max Address Ext  Write DMA Ext  Write DMA FUA Ext  Write FPDMA Queued  Write Multiple Ext  Write Multiple FUA Ext  Write Sector(s) Ext  Write Uncorrectable Ext

The 48-bit Address feature set operates in LBA addressing only. Devices also implement commands using 28-bit addressing, and 28-bit and 48-bit commands may be intermixed.

In a device, the Features, the Sector Count, the Sector Number, the Cylinder High, and the Cylinder Low registers are a two-byte-deep FIFO. Each time one of these registers is written, the new content written is placed into the "most recently written" location and the previous content is moved to "previous content" location.

The host may read the "previous content" of the Features, the Sector Count, the Sector Number, the Cylinder High, and the Cylinder Low registers by first setting the High Order Bit (HOB, bit 7) of the Device control register to one and then reading the desired register. If HOB in the Device Control register is cleared to zero, the host reads the "most recently written" content when the register is read. A write to any Command Block register shall cause the device to clear the HOB bit to zero in the Device Control register. The "most recently written" content always gets written by a register write regardless of the state of HOB in the Device Control register.

Support of the 48-bit Address feature set is indicated in the Identify Device response bit 10 word 83. In addition, the maximum user LBA address accessible by 48-bit addressable commands is contained in Identify Device response words 100 through 103.

When the 48-bit Address feature set is implemented, the native maximum address is the value returned by a Read Native Max Address Ext command. If the native maximum address is equal to or less than 268,435,455, a Read Native Max Address shall return the native maximum address. If the native maximum address is greater than 268,435,455, a Read Native Max Address shall return a value of 268,435,455.

Hitachi hard disk drive specifications

9.13 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.

A device that implements the Streaming feature set shall implement the following minimum set of commands:

 Configure Stream  Read Stream PIO  Write Stream PIO  Read Stream DMA  Write Stream DMA  Read Log Ext

Support of the Streaming feature set is indicated in Identify Device work 84 bit 4. Note that PIO versions of these commands limit the transfer rate (16.6 MB/s), provide no CRC protection, and

limit status reporting as compared to a DMA implementation.

9.13.1 Streaming commands

The streaming commands are defined to be time critical data transfers rather than the standard data integrity critical commands. Each command shall be completed within the time specified in the Configure Stream command or in the streaming command itself in order to ensure the stream requirements of the AV type application. The device may execute background tasks as long as the Read Stream and Write Stream command execution time limits are still met.

Using the Configure Stream command, the host may define the various stream properties including the default Command Completion Time Limit (CCTL) to assist the device in setting up its caching for best performance. If the host does not use a Configure Stream command, the device shall use the CCTL specified in each streaming command, and the time limit is effective for one time only. If the CCTL is not set by Configure Stream command, the operation of a streaming command with a zero CCTL is device vendor specific. If Stream ID is not set by a Configure Stream command, the device shall operate according to the Stream ID set by the streaming command. The operation is device vendor specific.

The streaming commands may access any user LBA on a device. These commands may be interspersed with non-streaming commands, but there may be an impact on performance due to the unknown time required to complete the non-streaming commands.

The streaming commands should be issued using a specified minimum number of sectors transferred per command, as specified in word 95 of the Identify Device response. The transfer length of a request should be a multiple of the minimum number of sectors per transfer.

The host provided numeric stream identifier, Stream ID, may be used by the device to configure its resources to support the streaming requirements of the AV content. One Stream ID may be configured for each read and write operation with different command completion time limits be each Configure Stream command.

Hitachi hard disk drive specifications

9.13.1.1 Urgent bit

The Urgent bit in the Read Stream and Write Stream commands specifies that the command should be completed in the minimum possible time by the device and shall be completed within the specified Command Completion Time Limit.

9.13.1.2 Flush to Disk bit

The Flush to Disk bit in the Write Stream command specifies that all data for the specified stream shall be flushed to the media before posting command completion. If a host requests flushes at times other than the end of each Allocation Unit, streaming performance may be degraded. The Set Features command to enable/disable caching shall not affect caching for streaming commands.

9.13.1.3 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.

9.13.1.4 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.

9.13.1.5 Write Continuous bit

If the Write Continuous bit is set to one for the command, and an error is encountered, the device shall complete the request without posting an error. If an error cannot be resolved within the Command Completion Time Limit, the erroneous section on the media may be unchanged or may contain undefined data. A future read of this area may not report an error, even though the data is erroneous.

9.13.1.6 Handle Streaming Error bit

The Handle Streaming Error bit specifies to the device that this command starts at the LBA of a recently reported error section, so the device may attempt to continue its corresponding error recovery sequence where it left off earlier. This mechanism allows the host to schedule error recovery and defect management for content critical data.

9.13.2 Streaming Logs

The Streaming Data Transfer feature set requires two error logs and one performance log. These logs are accessed via the Read Log Ext command; the information included in the error logs is volatile and is not maintained across power cycles, hard resets, or sleep. These error logs are 512 bytes in length and retain the last 31 errors that occurred during any Streaming Data transfer.

9.14 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. L – Far End Retimed Loopback T – Far End Transmit only A – ALIGN Bypass (valid only in combination with T bit) S – Bypass Scrambling (valid only in combination with T bit)

9.15 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 Normal Idle mode.

Hitachi hard disk drive specifications

9.16 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. In Serial ATA, COMRESET is equivalent to hard reset and a non-commanded COMRESET may occur if there is an asynchronous loss of signal. Since COMRESET is equivalent to hardware reset, in the case of an asynchronous loss of signal some software settings may be lost without legacy software knowledge. In order to avoid losing important software settings without legacy driver knowledge, the software settings preservation ensures that the value of important software settings is maintained across a COMRESET. Software settings preservation may be enabled or disabled using SET FEATURES with a subcommand code of 06h. If a device supports software settings preservation, the feature shall be enabled by default.

9.16.1 COMRESET Preservation Requirements

The software settings that shall be preserved across COMRESET are listed below. The device is only required to preserve the indicated software setting if it supports the particular feature/command the setting is associated with.

INITIALIZE DEVICE PARAMETERS: Device settings established with the INITIALIZE DEVICE

PARAMETERS command.

Power Management Feature Set Standby Timer: The Standby timer used in the Power Management

feature set.

Read/Write Stream Error Log: The Read Stream Error Log and Write Stream Error Logs (accessed using

READ LOG EXT and WRITE LOG EXT).

Security mode state: The security mode state established by Security Mode feature set commands (refer

to section 6.13 of the ATA/6 specification). The device shall not transition to a different security mode state

based on a COMRESET. For example, the device shall not transition from the SEC5: Unlocked / not

Frozen state to state SEC4: Security enabled / Locked when a COMRESET occurs, instead the device shall

remain in the SEC5: Unlocked / not Frozen state.

SECURITY FREEZE LOCK: The Frozen mode setting established by the SECURITY FREEZE LOCK

command.

SECURITY UNLOCK: The unlock counter that is decremented as part of a failed SECURITY UNLOCK

command attempt.

SET ADDRESS MAX (EXT): The maximum LBA specified in SET ADDRESS MAX or SET ADDRESS

MAX EXT.

SET FEATURES (Write Cache Enable/Disable): The write cache enable/disable setting established by the

SET FEATURES command with subcommand code of 02h or 82h.

SET FEATURES (Set Transfer Mode): PIO, Multiword, and UDMA transfer mode settings established by

the SET FEATURES command with subcommand code of 03h.

SET FEATURES (Advanced Power Management Enable/Disable): The advanced power management

enable/disable setting established by the SET FEATURES command with subcommand code of 05h or 85h.

The advanced power management level established in the Sector Count register when advanced power

management is enabled (SET FEATURES subcommand code 05h) shall also be preserved.

SET FEATURES (Read Look-Ahead): The read look-ahead enable/disable setting established by the SET

FEATURES command with subcommand code of 55h or AAh.

SET FEATURES (Reverting to Defaults): The reverting to power-on defaults enable/disable setting

established by the SET FEATURES command with a subcommand code of CCh or 66h.

SET MULTIPLE MODE: The block size established with the SET MULTIPLE MODE command.

9.17 SATA II Optional Features

There are several optional features defined in SATA II. The following shows whether these features are

supported or not.

9.17.1 Asynchronous Signal Recovery

The device supports asynchronous signal recovery defined in SATA II.

9.17.2 Device Power Connector Pin 11 Definition

SATA II specification defines that Pin 11 of the power segment of the device connector may be used to

provide the host with an activity indication and disabling of staggered spin-up. The device does not support

both usage of Pin 11.

9.17.3 Phy Event Counters

Phy Event Counters are an optional feature to obtain more information about Phy level events that occur on the interface. This information may aid designers and integrators in testing and evaluating the quality of the interface. A device indicates whether it supports the Phy event counters feature in IDENTIFY (PACKET) DEVICE Word 76, bit 10. The host determines the current values of Phy event counters by issuing the READ LOG EXT command with a log page of 11h. The counter values shall not be retained across power cycles. The counter values shall be preserved across COMRESET and software resets.

The counters defined can be grouped into three basic categories: those that count events that occur during Data FIS transfers, those that count events that occur during non-Data FIS transfers, and events that are unrelated to FIS transfers. Counters related to events that occur during FIS transfers may count events related to host-to-device FIS transfers, device-to-host FIS transfers, or bi-directional FIS transfers. A counter that records bi-directional events is not required to be the sum of the counters that record the same events that occur on device-to-host FIS transfers and host-to-device FIS transfers.

Implementations that support Phy event counters shall implement all mandatory counters, and may support any of the optional counters as shown in 0. Note that some counters may increment differently based on the speed at which non-Data FIS retries are performed by the host and device. Implementations may record CRC and non-CRC error events differently. For example, there is a strong likelihood that a disparity error may cause a CRC error. Thus, the disparity error may cause both the event counter that records non-CRC events and the event counter that records CRC events to be incremented for the same event. Another example implementation difference is how a missing EOF event is recorded; a missing EOF primitive may imply a bad CRC even though the CRC on the FIS may be correct. These examples illustrate that some Phy event counters are sensitive to the implementation of the counters themselves, and thus these implementation sensitive counters cannot be used as an absolute measure of interface quality between different implementations.

9.17.3.1 Counter Reset Mechanisms

There are two mechanisms by which the host can explicitly cause the Phy counters to be reset. The first mechanism is to issue a BIST Activate FIS to the device. Upon reception of a BIST Activate FIS the device shall reset all Phy event counters to their reset value. The second mechanism uses the READ LOG EXT command. When the device receives a READ LOG EXT command for log page 11h and bit 0 in the Features register is set to one, the device shall return the current counter values for the command and then reset all Phy event counter values.

Each counter begins with a 16-bit identifier. 0 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. There is no required ordering for event counters within the log page; the order is arbitrary and selected by the device vendor.

For all counter descriptions, „transmitted‟ refers to items sent by the device to the host and „received‟ refers to items received by the device from the host.

Bits 14:12 of the counter identifier convey the number of significant bits that counter uses. All counter values consume a multiple of 16-bits. The valid values for bits 14:12 and the corresponding counter sizes are:

1h 16-bit counter 2h 32-bit counter 3h 48-bit counter 4h 64-bit counter

Any counter that has an identifier with bit 15 set to one is vendor specific. This creates a vendor specific range of counter identifiers from 8000h to FFFFh. Vendor specific counters shall observe the number of significant bits 14:12 as defined above.

Table 39 Phy Event Counter Identifiers

Hitachi hard disk drive specifications

9.17.3.2.1 Counter Definitions

The counter definitions in this section specify the events that a particular counter identifier represents.

9.17.3.2.1.1 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.

9.17.3.2.1.2 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.

9.17.3.2.1.3 Identifier 002h

The counter with identifier 002h returns the sum of (the number of transmitted Device-to-Host Data FISes to which the host responded with R_ERRP) and (the number of received Host-toDevice Data FISes to which the device responded with R_ERRP).

9.17.3.2.1.4 Identifier 005h

The counter with identifier 005h returns the sum of (the number of transmitted Device-to-Host non-Data FISes to which the host responded with R_ERRP) and (the number of received Host-toDevice non-Data FISes to which the device responded with R_ERRP). Retries of non-Data FISes are included in this count.

9.17.3.2.1.5 Identifier 009h

The counter with identifier 009h returns the number of times the device transitioned into the PHYRDY state from the PHYNRDY state, including but not limited to asynchronous signal events, power management events, and COMRESET events. If interface power management is enabled, then this counter may be incremented due to interface power management transitions.

9.17.3.2.1.6 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.

9.17.3.2.1.7 Identifier 00Bh

The counter with identifier 00Bh returns the number of received Host-to-Device FISes of all types (Data and non-Data) to which the device responded with R_ERRP due to CRC error.

9.17.3.2.1.8 Identifier 00Dh

The counter with identifier 00Dh returns the number of received Host-to-Device FISes of all types (Data and non-Data) to which the devices responded with R_ERRP for reasons other than CRC error.

9.18.1 Overview

9.18.1.1 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:

Table 41 SCT Log Page and direction

There are two ways to access the log pages: using SMART READ/WRITE LOG and READ/WRITE LOG EXT. Both sets of commands access the same log pages and provide the same capabilities.

The log directory for log pages E0h and E1h should report a length of one. The length of log page E1h does not indicate the length of an SCT data transfer.

If SMART is supported, but not enabled, the drive supports SMART READ/WRITE LOG for Log page E0h and E1h.

If security is enabled and password has not been issued to unlock the device, all SCT commands will fail.

9.18.1.2 Capability definition

Capability Identification is performed by issuing Identify Device command. Word 206 of Identify Data is used to determine if SCT is enabled and which SCT Action Codes are supported.

Table 42 Identify Device Information Word 206

Hitachi hard disk drive specifications

9.18.1.3 SCT Command Nesting and intermingling with Standard commands

In general, standard ATA commands can be intermingled with SCT Commands but SCT commands cannot be nested. SCT commands that do not require a follow-on data transfer operation never have an issue with being intermixed with any ATA commands or each other. SCT commands that do require data transfer, on the other hand, may not be nested; that is, if a key command that requires a data transfer is issued, all data transfer - to or from the host - must complete before another SCT command is issued. In most cases, however, ATA read/write commands may be inserted in between SCT data transfers, that is, between complete SMART Read Log/Write Log commands. Furthermore, any reset (power-on, software or hardware) will cause the SCT command to be aborted.

9.18.1.4 Resets

In 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.

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. The SCT status may be acquired any time that the host is allowing to send a command to the device. This command will not change the power state of the drive, nor terminate any background activity, including any SCT command in progress.
