4.4 Drive organization 4.4.1 Drive Format Upon shipment from Hitachi Global Storage Technologies manufacturing the drive satisfies the sector continuity in the physical format by means of the defect flagging strategy described in Section 5 on page 23 in order to provide the maximum performance to users. 4.4.2 Cylinder allocation Physical cylinder is calculated from the starting data track of 0. It is not relevant to logical CHS.
4.5 Performance characteristics Drive performance is characterized by the following parameters: Command overhead Mechanical positioning 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.

7 General 7.1 Introduction This specification describes the host interface of HDS7210xxCLA3yz / HUA7220xxCLA33z / HCS5C10xxCLA382 / HCS7210xxCLA3y2 / HDS5C10xxCLA382 . The interface conforms to the following working documents of Information technology with certain limitations described in the chapter 0 “Deviations from Standard” on page 47 – Serial ATA II: Extensions to Serial ATA Revision 2.6 7.
8 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.
8.4 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.
8.7 Drive Address Register Drive Address Register Table 29 7 6 5 4 3 2 1 0 HIZ -WTG -H3 -H2 -H1 -H0 -DS1 -DS0 Drive Address Register This register contains the inverted drive select and head select addresses of the currently selected drive. Bit Definitions HIZ High Impedance. This bit is not driven and will always be in a high impedance state. -WTG -Write Gate. This bit is 0 when writing to the disk device is in progress. -H3,-H2,-H1,-H0 -Head Select.
8.9 Error Register Error Register 7 6 5 4 3 2 1 0 ICRCE UNC 0 IDNF 0 ABRT TK0NF AMNF Table 31 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.
8.10 Features Register This register is command specific. This is used with the Set Features command, SMART Function Set command and Format Unit command. 8.11 Sector Count Register This register contains the number of sectors of data requested to be transferred on a read or write operation between the host and the device. If the value in the register is set to 0, a count of 256 sectors (in 28-bit addressing) or 65,536 sectors (in 48-bit addressing) is specified.
8.13 Status Register Status Register 7 6 5 4 3 2 1 0 BSY DRDY DF DSC /SERV DRQ CORR IDX ERR 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.
9 General Operation Descriptions 9.1 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, spins up the HDA, tests speed and other mechanical parametric, and sets default values. 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.
9.1.1 Register Initialization Register Default Value Error Diagnostic Code Sector Count 01h Sector Number 01h Cylinder Low 00h Cylinder High 00h Device/Head 00h Status 50h Alternate Status 50h Table 34 Default Register Values After power on, hard reset, or software reset, the register values are initialized as shown in Table 34.
9.3 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 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.
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 HDS5C10xxCLA382 implement the following set of functions. / HCS7210xxCLA3y2 / 1. A Standby timer 2. Idle command 3. Idle Immediate command 4. Sleep command 5.
9.4.4 Interface Capability for Power Modes Each power mode affects the physical interface as defined in the following table: Mode BSY RDY Interface active Media Active x x Yes Active Idle Standby sleep 0 0 x 1 1 x Yes Yes No Active Inactive Inactive Table 36 Power conditions Ready (RDY) is not a power condition. A device may post ready at the interface even though the media may not be accessible.
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.
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.
9.6 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. Security Set Password ('F1'h) Security Unlock ('F2'h) Security Erase Prepare ('F3'h) Security Erase Unit ('F4'h) Security Freeze Lock ('F5'h) Security Disable Password ('F6'h) 9.6.
9.6.3 Password This function can have 2 types of passwords as described below. Master Password When the Master Password is set, the device does NOT enable the Device Lock Function, and the device can NOT be locked with the Master Password, but the Master Password can be used for unlocking the device locked. Identify Device Information word 92 contains the value of the Master Password Revision Code set when the Master Password was last changed. Valid values are 0001h through FFFEh.
9.6.4.3 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.
9.6.4.4 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.
9.6.5 Command Table This table shows the device's response to commands when the Security Mode Feature Set (Device lock function) is enabled.

9.7 Host Protected Area Feature 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.
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.
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.
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.
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.
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.
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.
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.
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.
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.
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.
9.17.3.2 Counter Identifiers 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.
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.
9.17.3.3 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.

9.18 SCT Command Transport feature Set 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.
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.
9.18.2 SCT Command Protocol 9.18.2.1 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. 9.18.2.1.
9.18.2.1.
9.18.2.1.3 Key Sector Format An SCT command (Key Sector) is always 512 bytes long. Table below shows the generic format of an SCT command. Byte 1:0 Field Action Code Words 1 3:2 Function Code 1 X:4 Y:x+1 … Parameter1 Parameter2 … Total Words Depends on command Depends on command … 256 Description This field defines the command type and generally specifies the type of data being accessed, such as sector or physical action being performed, such as seek.
9.18.2.1.4 Extended Status Code Status Code 0000h 0001h 0002h 0003h 0004h 0005h 0006h 0007h 0008h 0009h 000Ah 000Bh 000Ch 000Dh 000Eh 000Fh 0010h 0011h 0012h 0013h 0017h 0018h-BFFFh C000h-C002h C003h C004h C005h C006h C007h-FFEFh FFF0h-FFFEh FFFFh Definition Command complete without error Invalid Function Code Input LBA out of range Request sector count overflow. The number of sectors requested to transfer (Sector Count register) in the read or write log command is larger than required by SCT command.
9.18.2.2 Data transfer Once an SCT command has been issued, status can be checked and data can be transferred. Data transfer uses log page E1h. 9.18.2.2.1 Read/Write SCT Data Using SMART Command Block Output Registers Register 7 6 5 4 3 2 1 0 Feature D5h(Read)/D6h(Write) Sector Count Number of sectors to be transferred Sector Number E1h Cylinder Low 4Fh Cylinder High C2h Device/Head - - - D - Command - - - B0h Table 50 Input Registers of SCT Data Transfer Using SMART 9.18.2.2.
9.18.2.3 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.
9.18.2.3.3 Format of SCT Status Response Byte 1:0 3:2 Type Word Word Field Name Format Version SCT Version Value 0003h 5:4 Word SCT Spec.
205 209:206 Byte Dword Reserved 00h 213:210 Dword Under Limit Count 479:214 511:480 Byte[275] Byte[32] Reserved Vendor Specific Over Limit Count Number of temperature recording Intervals since the last power-on reset where the recorded temperature was greater than Max Op Limit. See table 93 for information about this Interval. Number of temperature recording Intervals since the last power-on reset where the recorded temperature was less than Min Op Limit.
9.18.3 SCT Command Set 9.18.3.1 SCT Write Same (action code : 0002h) Inputs: (Key Sector) Word Name Value Description 0 Action Code 0002h This action writes a pattern or sector of data repeatedly to the media. This capability could also be referred to as “Write All” or “Write Same”.
Once the key sector has been issued, if the Function Code was 0002h or 0102h and the TF Data indicates that the drive is ready to receive data, log page E1h should be written to transfer the data. This command can change the Segment Initialized Flag. If the command writes all the user addressable sectors and completes without encountering an error or being aborted, then the “Segment Initialized Flag” (bit 0 of the Status Flags in the SCT Status. See0) shall be set to 1.
Implementation note for Background Operation (Function code = 0001h, 0002h) In this mode, the drive will return command completion status when the drive finished receiving data. Any command, including IDENTIFY DEVICE, other than SCT Status, issued to the drive while this command is in progress will terminate the SCT Write Same command. The incoming command is executed. Use the SCT Status command to retrieve status information about the current SCT command.
9.18.3.2 Error Recovery Control command (action code : 0003h) Inputs: (Key Sector) Word Name Value Description 0 Action Code 0003h Set the read and write error recovery time 1 Function Code 0001h Set New Value 0002h Return Current Value 0001h Read Timer 0002h Write Timer If the function code is 0001h, then this field contains the recovery time limit in 100ms units. The minimum SCT timeout value is 65 (=6.5 second). When the specified time limit is shorter than 6.
9.18.3.
Feature Code State Definition 0001h 0001h : Allow write cache operation to be determined by Set Feature command 0002h : Force write cache enabled 0003h : Force write cache disabled If State 0001h is selected, the ATA Set Feature command will determine the operation state of write cache. If State 0002h or 0003h is selected, write cache will be forced into the corresponding operation state, regardless of the current ATA Set Feature state.
9.18.3.
Byte Size Field Name Description 1:0 Word Format Version Data table format version (=0002h) 3:2 Word Sampling Period Absolute HDA Temperature sampling period in minutes. 0000h indicates sampling is disabled. 5:4 Word Interval Timer interval between entries in the history queue. 6 Byte Max Op Limit Maximum recommended continuous operating temperature. This is a one byte 2‟s complement number that allows a range from -127°C to +127°C to be specified. 80h is an invalid value.
(Queue Size+33):34 Byte[Queue Size] Queue Buffer This is a circular buffer of absolute HDA Temperature values. 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 Not 1.
10 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 1.0a (Section 9. device command layer protocol) and Serial ATA II: Extensions to Serial ATA 1.0a (Section 4. Command layer) about each protocol. For all commands, the host must first check if BSY=1, and should proceed no further unless and until BSY=0.
