Safety Instructions

1. The product is not authorized for use in life support devices or syst ems or other applicat ions that pose a significant risk of personal injury.

2. Since the drive uses glass media for the disk platter, opening of Metal Head Disk Assembly (HDA) may cause bodily injury. Warranty void in case of opened HDA or any broken HDA seals. Don’t open the HDA or break any HDA seals.

3. Dropping of the HDD may cause bodily injury. Handle with care.

4. Do not cover the breather hole. If the hole was cov ered w it h any material, it shall result in permanent damage to the drive and/or loss of data. Label or seal shall be attached on the cover avoiding the breather hole. Warranty void if the breather hole was covered.

5. Do not hit the interface connector pins against other objects. Do not make contact w ith the interface connector pins. Contact causes pin dent, electrical discharge distraction or contact failure. Also, pins or HDA corners may cause bodily injury. Handle with care.

6. Observe Clause 3.3 “Drive Usage Condition Specificat ions” . Since r eliability and product life depends on usage conditions, please consult our sales or application engineers.

7. Keep usage conditions within specifications (Power Supply, Environment, etc.). If the conditions are not kept within the specifications, failures may occur.

8. Hot swapping (Power-on swapping) can damage the drive. The drive shall be sw apped during Pow er O ff only.

9. Electro Static Discharge (ESD) can damage the drive. Protect the drive from ESD during handling.

10. Voltage rise time 5 - 100 ms at power on is required for power supply. The power supply v olt age must not be under below GND level (0 V) at power off.

11. This product is required over current protection for possible combustion due to circuit or component failure. Secondary over current protection shall be prepared by the system. The requirement of the current limitation is max. 10 A for the protection.

12. Improper insertion of connector or wrong jumper setting may cause catastrophic failures. Referring to

this manual prior to the connector insertion or jumper setting can help to insure correct insertion.

13. If a foreign conductive substance (metallic powder, fluid, etc.) adheres to active metal of the driv e (Printed pattern, component lead, etc. on PCBA), it may cause catast rophic failures. Cust omer should protect the drive from the above condition.

14. The PCBA side of the drive should be covered with insulation sheet if t he active metal of host system may contact to the PCBA of the drive. If the insulation sheet is not provided for the possible contact of the live metal, failures may occur.

15. Shock can result in permanent damage to the drive and/or loss of data. Prevent shocks, which is often incurred by dropping, knocking over, or hitting the drive.

16. To fix the drive, use the size of screws and the torque recommended in this manual. If nonrecommended size screws and torque are used, it may cause catastrophic failures.

17. Do not press top cover. It may cause catastrophic failures. In case of steel plate installation on HDD

cover side, the spacing between HDD cover and steel plate should be kept more than 2 mm. If this spacing is not kept for the steel plate, it may affect Load/Unload mechanism.

:Average time of seek is calculated under the following condition. (Read/Write ratio: Read only)

Average of 10,000 random seeks, Voltage 5.0V, Temperature 25°C. Maximum time of seek is calculated under the following condition. Average of 1,000 full stroke seeks, Voltage 5.0V, Temperature 25°C. This maximum time is not included the seek time by seek retry.

: Periodically, during start up, the drive may perform a spin up retr y operation. When this operation occurs,

the start up sound will change slightly and the ready timing will also be altered from typical time.

: Power on to Ready time could take up to 20 seconds in case of spin up retries under certain

conditions of the voltage specifications(Table 3.1) and environmental specifications(Table 3.2).

*4 :

For DC power input, the average current is measured at the connector of the PCBA of this drive and in

the nominal condition in which the power voltage and the temperature are 5.0V and 25°C, respectively. Burst free (common mode). The average current may have some tolerance after power-on. The current

measurement is recommended at 5 minutes later after power-on.

Voltage rise time 5 - 100 ms at power on is required for power supply. The power supply voltage must not be under below GND lev el ( 0 V) at power off.

This product is required over current protection for possible combustion due to

circuit or component failure. Secondary over current protection shall be prepared by the system. The requirement of the current limitation is max. 10 A for the protection.

: For more information, refer to Section 6.1.

: This value is at Low Power Idle mode. The heads are unloaded.

: Power mode automatically enters to Low Power Active mode after Read/ Write operation. Head position

is kept on the same track before this power transition.

: Measured during random seek , and the seek interval is 1.5 revolution times (i.e. the average latency

and one revolution).

: Measured while reading or writing 16 sectors of data located on the same track.

3.4 Load/Unload Specifications

Load /Unload is a mechanism to load/unload the heads on the disk surfaces.

3.4.1 Normal Load/Unload

Normal load/unload operations are limited to maximum 300,000 times during HDD life. The normal unload operation is performed by the following commands.

Standby

Standby Immediate

Sleep

Also, the normal unload is automatically performed by control software, during Idle mode. The abov e normal unload time does not include an emergency unload as explained in Sec. 3.4.2.

3.4.2 Emergency Unload

The emergency unload is occurred by unexpected power down, and is limited to maximum 20,000 times during HDD life. Since normal unload can not be performed by the softwar e cont r o l aft er power off, the heads are unloaded by a hardware control. The maximum number of emergency unload is defined separately.

3.4.3 Required Power Off Sequence

To operate the load/unload normally, the following BIOS sequence is required by Host system before power off.

[Sequence #1]: Execute one of following commands.

Standby

Standby Immediate

Sleep

Note:

Such as Soft Reset, Flush Cache command or Check Power Mode command does

not unload the heads. Soft Reset does not unload the heads from DK23CA-xx.

[Sequence #2]: Check the Status Register, and wait the command complete.

Note:

The head is unload by the sequence #1 command, and the command completion

normally takes about 400 ms. Considering the error retries, BIOS timer should be set to over 30 sec by the Host side.

[Sequence #3]: Power off the drive

Above sequence is required for the Host system at Power off, Suspend and Hibernation operations.

DA0-2 33,35,36 I This is a register address signal from the host system.

PDIAG-:CBLID-

(*1)

34 I/O The PDIAG- signal is asserted by Device 1 to indicate to Device 0

that it has completed diagnostics. This signal is pulled up inside the device.

The host may sample CBLID- after a power-on or hardware reset in order to detect the presence or absence of an 80-conductor cable assembly by performing the following steps:

a) The host shall wait until the power on or hardware reset

sequence is complete for all devices on the cable;

b) If Device 1 is present, the host should issue IDENTIFY DEVI CE

or IDENTIFY PACKET DEVICE and use the returned data to determine that Device 1 is compliant with ATA-3 or subsequent standards. Any device compliant with ATA-3 or subsequent standards releases PDIAG- no later than after the first command following a power on or hardware reset sequence.

If the host detects that CBLID- is connected to ground, an 80conductor cable assembly is installed in the system. If the host detects that this signal is not connected to ground, an 80-conductor cable assembly is not installed in the system.

6.3.2.2 Command BSY Timing

The manner in which a command is accepted varies by the three classes of command acceptance all predicated on the fact that to receive a command, BSY=0. The following describes by t he condit ions under which busy is set after receipt of a command.

Class1 - The device sets busy within 400 ns.

Class2 - The device will set BSY within 400 ns, t hen set s up t he sector buffer for a write operation, then sets DRQ, and clears BSY within 400 ns of setting DRQ .

Note

: DRQ may be set so quickly on classes 2 that the BSY transit ion is t oo short for BSY=1 to

be recognized.

6.3.2.3 PIO Data In Commands

Execution includes the transfer of one or more 512 byte sectors of data from the device to t he host .

1) The host writes any required parameters to the Features, Sector Count , Sect or Number, Cylinder Low, Cylinder High, and Device/Head registers.

2) The host writes the command code to the Command Register.

3) The device sets BSY and prepares for data transfer.

4) When a sector(block) of data is available, the device sets DRQ and clears BSY prior to asserting INTRQ.

5) After detecting INTRQ, the host reads the Status Register, t hen reads one sect or (block) of data via the Data Register. In response to the Status Register being read, t he device negates INTRQ.

6) The device clears DRQ. If transfer of another sector (block) is required, the device also sets BSY and the above sequence is repeated from 4).

6.3.2.3.1 Identify Dev i ce [ECh]

The Identify Device command enables the host to receive parameter information from the device. When the command is issued, the device sets BSY, stores the required parameter information in the sector buffer, sets DRQ, and generates an interrupt. The host then reads the information from the sector buffer through the Data Register. The parameter words are defined in Table 6.5 and 6.6. All reserved bits or words shall be zero.

6.3.2.3.2 Read Buffer [E4h]

The Read Buffer command enables the host to read the current contents of the device's sector buffer. When this command is issued, the device sets BSY, sets up the sector buffer for a read operation, sets DRQ, clears BSY, and generates an interrupt. The host t hen reads up t o 512 bytes of data from the sector buffer.

6.3.2.3.3 Read Sectors [20h, 21h]

This command reads sectors as specified in the Sector Count Register. The read operation begins at the sector specified in the Sector Number Register. An implied seek is done if needed, after which the device searches for the target sector. If the target sector is not found within two index periods, then with retries disabled an ID Not Found Error is posted, but with retr ies ot her at tempts are made to try and read the target sector. DRQ is set prior t o dat a transfer regardless of the presence or absence of an error condition. At command completion, the Command Block Registers contain the cylinder, head, and sector numbers of the last sector read. If an error occurs, the read terminates at the sector where the error occurred. The Command Block Registers contain the cylinder, head, and sector numbers where the error occurred.

6.3.2.3.4 Read Long [22h, 23h]

The Read Long command performs similarly to the Read Sectors command except that it returns the data and the ECC bytes contained in the data field of the desired sector. During a Read Long command, the device does not check the ECC bytes to determine if there has been a data error. Only single sect or read long operations are supported. The number of ECC bytes t r ansfer r ed w ill be 4 Bytes (Default). If the ECC transfer length is changed by Feature register 44h, 24 bytes of ECC will be transferred.

6.3.2.3.5 Read Multiple [C4h]

This command is similar to the Read Sectors command, except interrupts are not generated on every sector, but on the transfer of a block which contains the number of sectors defined by a Set Multiple command. The number of sectors defined by a Set Multiple command is transferred without intervening interrupts. DRQ qualification of the transfer is required only at the start of the dat a block, not on each sector. The Set Multiple Mode command, which must be executed prior to the Read Multiple command, sets the block count of sectors to be transferred. When the Read Multiple command is issued, the Sector Count Register contains the number of sectors (not the number of blocks or the block count) requested. If the number of requested sectors is not evenly divisible by t he block count, as many full blocks as possible are transferred, followed by a final, partial block transfer for n sectors, where n = residue of {Sector Count/Sect or Count per Block}. Disk errors encountered during Read Multiple commands are posted at the beginning of the block or partial block transfer, but DRQ is still set and the data transfer should be executed as it normally would, including transfer of corrupted data, if any. Subsequent blocks or partial blocks are transferred only if the error was a correctable data error. All other errors cause the command to stop after transfer of the block that contained the error. Interrupts are generated when DRQ is set at the beginning of each block or partial block.

K6602637 Rev.3

02.27.01

- 46 -

6.3.2.4 PIO Data Out Commands

Execution includes the transfer of one or more 512-byte sectors of data from the host to the device.

1) The host writes any required parameters to the Features, Sector Count , Sect or Number, Cylinder Low, Cylinder High, and Device/Head Regist ers.

2) The host writes the command code to the Command Register.

3) The device sets the DRQ when it gets ready t o accept t he first sect or(block) of data.

4) The host writes one sector block of data to the Data Register.

5) The device clears DRQ and sets BSY.

6) When the device has processed the sector(block), it clears BSY and set the INTRQ signal to "ON". The device sets DRQ again if another sector is required to transfer.

7) After detecting INTRQ, the host reads the Status Register.

8) The device clears the interrupt.

9) If another sector(block) is required to be transferred, the above steps 3) to 8) are repeated.

6.3.2.4.1 Write Buffer [E8h]

This command allows the host to write 512 bytes of data to the sect or buffer of the device. When the Write Buffer command and the Read Buffer command are issued consecutively, the same data is read.

6.3.2.4.2 Write Sectors [30h, 31h]

This command writes sectors as specified in the Sector Count Register, beginning at the specified sector. An implied seek is done if needed, after which the device searches for the target sector. If the target sect or is not found within two index periods, then with retries disabled, an I D Not Found Error is post ed, but with retries enabled, other attempts are made to try and read the target sector. After correctly reading a target sector, the data in the sector buffer is written to t he device, followed by the ECU bytes. At command completion, the Command Block Registers contain the cylinder, head, and sector numbers of the last sector written. If an error occurs during a write of more than one sector, wr it ing terminates at the sector where the error occurs. The command Block Registers contain the cylinder, head, and sector numbers of the sector where the error occurred.

6.3.2.4.3 Write Long [32h, 33h]

This command is similar to the Write Sectors command, except that it writes the data and the ECC bytes directly from the host; the device does not generat e t he ECC bytes itself. Only single sector Write Long operations are supported. The transfer of the ECC bytes shall be 8-bits wide. The number of ECC by t es transferred will be 4 bytes (Default). If the ECC transfer length is changed by Features Register = 44h, 24 bytes of ECC will be transferred.

6.3.2.4.4 Write Multiple [C5h]

This command is similar to the Write Sectors command, except interrupts are not generated on every sector, but on the transfer of a block which contains the number of sectors defined by the Set Multiple command. The number of sectors defined by the Set Multiple command is transferred without intervening interrupts. DRQ qualification of the transfer is required only at the start of t he dat a block, not on each sector. The Set

K6602637 Rev.3

02.27.01

- 47 -

Multiple Mode command, which must be executed prior to the Write Multiple command, sets the block count of sectors to be transferred. When the Write Multiple command is issued, the Sector count Register contains the number of sectors (not the number of blocks or the block count) requested. If the number of requested sector is not evenly divisible by the block count, as many full blocks as possible are transferred, followed by a final, partial block transfer. The Partial block transfer shall be for n sectors, where n = residue of {Sector Count/(Sector Count per Block)} Disk errors encountered during Write Multiple commands are posted after the attempted disk write of the block or partial block transferred. The write operation ends with the sect or in error, regardless of the position in the block. Subsequent blocks are not transferred in the event of an error. Interrupts are generated when DRQ is set at the beginning of transfer of each block, except first block.

6.3.2.4.5 Format Track [50h]

This command provides a means to mark a sector as bad or to reassign it logically. The logical track address is specified in the Cylinder High and Cylinder Low Registers, and the number of sectors is specified in the Sector Count Register. When the command is accepted, the device sets the DRQ bit and waits for the host fill the sector buffer. When the sector buffer is filled with 512 bytes of data, the device clears DRQ, sets BSY, and begins the command execution. One 16-bit word of format table data represents each formatting method of sectors. The words are contiguous from the start of a sector. If the format table data remains below 512 bytes after words of the last sector are entered, the buffer should be filled with "0" DD15-8 contains the sector number, and DD7-0 contains one of the descriptor values defined as follows.

Code Formatting method

00h Formats a sector as good This command is used only in the Physical mode, but the Physical mode is not released. I f the device is not in the Physical mode, the device executes a vendor specific operation.

6.3.2.5 Non-Data Commands

Execution of these commands does not involve any data transfer.

1) The host writes any required parameters to the registers.

2) The host writes the command code to the Command Registers.

3) The device sets BSY.

4) When the device has completed processing, it clears BSY and asserts INTRQ.

5) The host reads the Status Register.

6) The device negates INTRQ.

6.3.2.5.1 Initialize Dev i ce Parameters [91h]

These parameters allow the host to set the number of sectors per track and the number of heads per cylinder. Upon receipt of the command, the device sets BSY, saves the specified parameters, clears BSY, and generates an interrupt. The only two register values that this command uses are the Sector Count Register that specifies the number of sectors per track, and the Device/Head Register that specifies the number of heads minus 1. The DRV bit is used for selecting a device. The sector count and head values are not checked for validity by this command. I f t hey are invalid, no error will be posted until an illegal access is made by some other command.

6.3.2.5.2 Read Verify [40h, 41h]

This command is same as the Read Sectors command, except that DRQ is never set and no data is transferred to the host. When the requested sectors have been verified, the device clears BSY and generates an interrupt. Upon command completion, the Command Block Registers contain the cylinder, head, and sector numbers of the last sector verified. If an error occurs, the verify terminates at the sector where the error occurs. The Command Block Registers contain the cylinder, head, and sector numbers of the sector where the error occurred. The Sector Count Register shall contain the number of sectors not yet verified.

6.3.2.5.3 Recalibrate [1Xh]

This command performs a physical seek to track 0. Upon receipt of the command, the device sets BSY and issues a seek to cylinder 0. The device then waits for the seek to complete before updating status, clearing BSY, and generating an interrupt. If the device cannot reach cylinder 0, a Track Not Found error is posted.

6.3.2.5.4 Seek [7Xh]

This command indicates a logical seek to the track and head specified in the Command Block Registers. The device will set DSC=1 after the seek has Completed. If anot her command is issued t o the device while a seek is being executed, the device sets BSY=1, waits for the seek to complete, and t hen begins execut ion of the command.

This command allows the device to specify the number of sectors per block to perform Read Multiple and Write Multiple operations. The Sector Count Register is loaded with the number of sectors per block. Block sizes of 2, 4, 8, and 16 sectors are supported. Upon receipt of the command, the dev ice set s BSY=1 and checks the Sector Count Register. If the Sector Count Register contains a valid value, then the value is loaded for all subsequent Multiple commands and execution of those commands is enabled. If an invalid value is specified, an Aborted Command error is posted and execution of the Multiple commands is disabled. The Multiple commands cannot be executed in the default mode at power on or after a hardware reset.

(1) Low power consumption modes

The drive supports the following low power consumption modes.

Active mode : The spindle motor is rotated. Seek and Read/Write operations are activated. However,

the power mode is moved to Low Power Active mode if the host does not issue any command within 200 ms after previous command completion. The Low Power Active mode is a low power consumption mode cutting the power of the drive control circuit, but the drive is keeping the active state of Seek and Read/Write operations.

Idle mode: Refer to Sec. 6.3.2.6.2 “Advanced Power Management”.

Standby mode: State of ready to receive commands. State of ready to receive commands, but the

spindle motor is stopped. If the device receive a command with seek operation, the spindle motor is rotated and the command is executed.

Sleep mode: This mode is the lowest power mode. The spindle motor is stopped. The device cannot

receive the command except Hardware Reset and Software Reset.

(3) Standby Timer

Standby timer is provided for automatic power saving control. The dev ice aut omatically moves to the Standby mode if the host does not issue a command within the timer period. The Standby timer is disabled at power-on. The Standby timer value is changeable using Idle and Standby commands. The timer can be set up to 30 minutes.

6.3.2.6.2 Advanced Power Management

The host can select the power saving control pattern by Advanced Power management (APM). The device performs an intelligent power saving control based on the selected pattern by host .

Using Set Feature command and Sector Count register can set the APM operation mode. The Sector count value is related to the performance level and the power consumption level. I f the Sector Counter value is set to 01h, the power consumption is getting better, but t he performance is gett ing worse. If the large Sector Count is set to FEh, the performance is getting better sacrificing the power consumption. The device has five levels of APM operation mode(APM mode 0,1,2,3 and 4) depending on the Sector Counter values from 01h to FEh.

(1) Command Set

Using the following command, the APM control can be set the mode and reset the mode.

Set Feature command, Enable Advanced Power Management sub-command.

(Command Code = EFh, Features = 05h)

Set Feature command, Disable Advanced Power Management sub-command.

(Command Code = EFh, Features = 85h)

The Enable Advanced Power Management sub-command enables the APM operation set by the Sector Count register. The Disable Advanced Power Management sub-command disables the APM operation. If the APM operation is disabled, the device performs APM mode 0.

The APM mode can be confirmed by Identify Device command as follows:

Identify Device Information Word 83 Bit 3: This bit is always set to “1” and indicates the APM

operation is supported.

Identify Device Information Word 86 Bit 3: IF this bit is set to “1”, it indicates the APM operation is

enabled.

Identify Device Information Word 91: This word reports an operation mode set by Set Feature

command and Enable Advanced Power Management sub-command.

6.3.2.7 DMA Data In/Out Commands

The Read DMA and Write DMA commands execute data transfer using the slave-DMA channel. The host is required to enable the slave-DMA feature, if using these commands.

1) The host initializes the slave-DMA feature, if using t hese commands.

2) The host write any required parameters to the Features, Sector Count , Sect or Number, Cylinder low, Cylinder High, and Device/Head registers.

3) The host writes the command code to the Command Register.

4) The device sets the DMARQ when it gets ready t o t r ansfer.

5) The slave-DMARQ channel qualifies data transfers to and from the device with DMARQ. The register contents are not valid during a DMA Data Phase.

6) The device generates the interrupt to the host, when the data transfer has completed.

7) The host resets the slave-DMA channel.

8) The host reads the Status Register. In response to the Status Regist er being read, the device negates INTRQ.

6.3.2.7.1 Read DMA [C8h, C9h]

This command executes in a similar manner to the Read Sectors command except for the following.

The host initializes a slave-DMA channel prior to issuing the command.

Data transfers are qualified by DMARQ and are performed by the slave-DMA channel.

The device issues only one interrupt per command indicating that data transfer has terminated and

status is valid.

If an error occurs, the read terminates at the sector where the error occurred. The command Block Registers contain the cylinder, head, and sector numbers where the error occurred.

6.3.2.7.2 Write DMA [CAh, CBh]

This command executes in a similar manner to the Write Sectors command except for the followings.

The host initializes a slave-DMA channel prior to issuing the command.

6.3.2.8 SMART Feature

The intent of self-monitoring, analysis, and reporting technology (SMART) is to prot ect user dat a and minimize the likelihood of 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 attempt to predict the likelihood of near-term degradation or fault condition. Providing t he host system the knowledge of a negative reliability condition, allows the host system to war n t he user of the impending risk of a data loss and advise the user of appropriate action. Support of this feature set is indicated in bit 0 of word 82 of the Identify Dev ice response.

The SMART commands use a single command code and are differentiated by the value placed in the Features register. The commands supported by this feature set are:

SMART Enable Operations

SMART Disable Operations

SMART Return Status

SMART Enable/Disable Attribute AUTOSAVE

SMART Save Attribute Values

SMART Enable/Disable Automatic Off-line

SMART Execute Off-line Immediate

SMART Read Log Sector

SMART Write Log Sector

6.3.2.8.1 Attribute Parameters

Attributes are the specific performance or calibration parameters that are used in analyzing the stat us of the device. Attributes are selected by the device manufacturer based on that attribute’s ability to contribute to the prediction of degrading or fault conditions for that particular device. The specific set of att r ibut es being used and the identity of these attributes is v endor specific and propriet ary.

Attribute values are used to represent t he r e lat ive reliability of individual performance or calibration attribut es. Higher attribute values indicate that the analy sis algorit hms being used by the device are predicting a lower probability of a degrading or fault condition existing. Accordingly, lower attribute values indicate that the analysis algorithms being used by the device are pr edict ing a higher pr obability of a degrading or fault condition existing. Each attribute value has a corresponding attribute threshold limit that is used for direct comparison to the attribute value to indicate the existence of a degrading or fault condit ion. The device manufacturer through design and reliability testing and analysis deter mine t he numer ical values of the attribute thresholds. Each attribute threshold represents the lowest limit to which it s corresponding at tribute 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. If one or more attribute values are less than or equal to their corresponding attribut e t hresholds, t hen t he device reliability status indicates an impending degrading or fault condition.

6.3.2.8.2 SMART Device Err or Log Repor t i ng

The intent of SMART Device Error Log Reporting feature is to augment the SMART feature set to prov ide additional diagnostic information on device that have generated error conditions. The device ret ains a specified amount of previously executed commands, and write this data along w it h the time of a triggered error condition to the existing SMART Read Logging Sectors.

The last five errors that device reported are gathered at all times the device is powered on except that logging of errors when in reduced power modes “standby mode and sleep mode”. A host can deliver the error information using the SMART READ LOG SECTOR command.

If SMART is disabled by the host, the device does not disable SMART device error log. Disabling SMART will only disable the delivering of error log infor mat ion via the SMART READ LOG SECTOR command.

If a device receives a firmware modification, all err or log data will be discarded and the device error count for the life of the device will be reset to z er o by client software “Download Utility”.

6.3.2.8.3 SMART Operation with Power Management Modes

When used in a system that is utilizing the power management feature set, a SM ART enabled device automatically saves its attribut e values upon receipt of an IDLE IMMEDIATE, STANDBY IMMEDIATE, or SLEEP command. If the device has been set to utilize t he standby timer, The device automatically perform a SMART SAVE ATTRIBUTE VALUES function prior to going from an Idle state to the Standby st ate.

6.3.2.8.4 SMART Function Default Set t i ng

The device is shipped from the device manufacturer's factory with SMART feature disabled. The system manufacturer or the applications shall enable SMART.

(1) Off-line mode

The following describes the protocol for executing a SMART EXECUTE OFF-LINE IMMEDIATE subcommand routine (including a self-test routine) in the off-line mode.

a) The device executes command completion before executing the subcommand routine. b) After clearing BSY to zero and set t ing DRDY to one after receiving the command, the device does not

set BSY nor clears DRDY during execution of the subcommand rout ine.

c) If the device is in the process of performing the subcommand routine and is interrupted by any new

command from the host except a SLEEP, SMART DISABLE OPERATIONS, SMART EXECUTE OFFLINE IMMEDIATE, or STANDBY IMMEDIATE command, the device suspends or aborts t he subcommand routine and services the host within two seconds after receipt of the new command. After servicing the interrupting command from the host the device immediately resumes the subcommand routine without any additional commands from the host.

d) If the device is in the process of performing a off-line routine and is interrupted by a SLEEP command

from the host, the device suspends the off-line routine and services the host aft er receipt of the command. If the device is in the process of performing any self-test routine and is interrupted by a SLEEP command from the host, the device aborts the self-test routine and services the host aft er receipt of the command.

e) If the device is in the process of performing the subcommand routine and is interrupted by a SMART

DISABLE OPERATIONS command from the host, the device aborts the subcommand routine and services the host within two seconds after receipt of the command.

f) If the device is in the process of performing the subcommand routine and is interrupted by a SMART

EXECUTE OFF-LINE IMMEDIATE command from the host, the device aborts the subcommand routine and services the host within two seconds after receipt of t he command. The dev ice t hen services the new SMART EXECUTE OFF-LINE IMMEDIATE subcommand.

g) If the device is in the process of performing the off-line routine and is interrupted by a STANDBY

IMMEDIATE command from the host, the device suspends the subcommand routine, and services the host within two seconds after receipt of the command. After receiving a new command that causes the device to exit a power saving mode, the device resumes the off-line routine w ithout any additional commands from the host unless these activities were aborted by the host.

h) If the device is in the process of performing the self-test routine and is interrupted by a STANDBY

IMMEDIATE command from the host, the device aborts the self-test routine, and services the host within two seconds after receipt of the command.

While the device is performing the subcommand routine it does not automatically change power states (e.g., as a result of its Standby timer expiring). If an error occurs w hile a device is performing a self-test routine the device discontinues the testing and places the t est results in the Self-test execution status byte.

K6602637 Rev.3

02.27.01

- 64 -

(2) Captive mode

When executing a self-test in captive mode, the device sets BSY to one and executes the self-test routine after receipt of the command. At the end of the routine the device places the results of t his rout ine in t he Self-test execution status byte and executes command completion. If an error occurs while a device is performing the routine the device discontinues its testing, place the results of t his rout ine in the Self-test execution status byte, and complete the command.

(3) SMART off-line routine

This routine only is performed in the off-line mode. The following tests are performed for the SMART off-line routine.

a) Raw Read Error Rate Measurement

Partial read scanning and Raw Read Error Rate measurement is performed.

b) Automatic sector reallocation in off-line read scanning for entire LBA.

(4) SMART Short self-test routine

Depending on the value in the Sector Number register, this self-test routine is performed in either the captive or the off-line or mode. This self-test routine should take on the order of one minute to complete.

The following tests are performed for the SMART short self-test routine:

a) Read test

Partial read scanning and Raw Read Error Rate measurement is performed.

b) Write test

User data area is not utilized, A part of t he fact or y data area is used. Write and Read test is performed for each head.

c) Servo test

Position Error Signal is checked for certain rotations in order to analyze RRO and settling accuracy.

d) Partial read scan test

Scans the first 300MB and the last 100MB 0f the device.

e) Seek performance test

Measures average seek time.

f) Throughput performance test

Measures throughput in the partial read scan test.

g) RAM test

6.3.2.9. Security Mode Feature

The Security Mode feature set is a password system that restricts access to user data stored on a device. The system has two passwords, User and Master and two security levels, High and Maximum. The security system is enabled by sending a user password to the device with the Security Set Password command. When the security system is enabled, access to user data on the device is denied after a power cycle until the User password is sent to the device with the Security Unlock command.

A Master password may be set in a addition to the User password. The purpose of the Master password is to allow an administrator to establish a password that is kept secret from the user, and which may be used to unlock the device if the User password is lost. Setting the Master password does not enable the password system.

The security level is set to High or Maximum with the Security Set Password command. The security level determines device behavior when the Master password is used to unlock the device. When the security level is set to High the device requires the Security Unlock command and the Master password to unlock. When the security level is set to Maximum the device requires a Security Erase Prepare command and a Security Erase Unit command with the master password to unlock.

The Security Freeze Lock command prevents changes to passwords until a following power cycle. The purpose of the Security Freeze Lock command is to prevent password setting attacks on the security system.

The security mode features allow a host to implement a security password syst em to prevent unauthorized access to the internal disk device.

The commands supported by this feature set are:

Security Set Password

Security Unlock

Security Erase Prepare

Security Erase Unit

Security Freeze Lock

Security Disable Password

Support of the security mode feature set is indicated in Identify Device response Word 128.

6.3.2.9.1 Security Mode Default Setting

The device is shipped with the master password set to 20h value(ASCII space ) and t he lock function disabled. The system manufacturer/dealer may set a new master password using the Security Set Password command, without enabling or disabling the lock function.

6.3.2.10 Protected Area Feature, Address Offset Feature

6.3.2.10.1 Protected Area Feature and Set Max Security Extensi on

A reserved area for data storage outside the normal operating system is required for several specializ ed applications. Systems may wish to store configuration data or save memory t o disk data in a locat ion that operation system can not change. Following commands are defined in this feature.

Read Max Address Command

Set Max Address Command

Set Max Set Password command

Set Max Lock command

Set Max Freeze Lock command

Set Max Unlock command

The Read Max Address Command returns the full size of disk. The Set Max Address Command sets the maximum address for commands.

The LBA/Cylinder changed by Set Max Address command affects the Identify Dev ice command. The LBA/Cylinder changed by Set Max Address command affects the Identify Dev ice command.

The Read Max Address command allows the host to determine the maximum native address space of the device even when a protected area has been allocated.

The Set Max Address command allows the host to redefine the maximum address of the user accessible address space. That is, when the Set Max Address command is issued with a maximum address less than the native maximum address, the device reduces the user accessible address space to the maximum set, providing a protected area above that maximum address. After the Set Max Address command has been issued, the device reports only the reduced user address space in response to an Identify Device command. A volatility bit in the Sector Count register allows the host to specify if the maximum address set is pr eser ved across power-on or hardware reset cycles. On power-on or hardware reset the dev ice maximum address returns to the last non-volatile address setting regardless of subsequent v olat ile Set Max Address commands. If the Set Max Address command is issued with a value that exceeds the native maximum address command aborted be returned.

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 cy cle but does persist over a hardware or software reset. This password is not related to the password used for t he Securit y 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.

K6602637 Rev.3

02.27.01

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.

6.3.2.10.2 Address Offset Feature

Computer systems perform initial code booting by reading from a predefined address on a disk drive. To allow an alternate bootable operating system to exist in a reserved are on disk driv e, Address O ffset Feature provides a Set Feature function to temporarily offset the drive address space. The offset address space wraps around so that the entire disk drive address space remains addressable in offset mode. The Set Max pointer is set to the end of the reserved area to protect t he data in the user area when operating in offset mode. This protection can be removed by an Set Max Address command to move the Set Max pointer to the end of the drive.

Set Feature Command Subcommand code 09h “Enable Address Offset Mode command” offsets address Cylinder 0, Head 0, Sector 1, LBA 0, to the start of a non-volatile reserved area established using the Set Max Address Command. The offset condition is cleared by Set Feature Command Subcommand 89h

“

Disable Address Offset Mode”, Software Reset, Hardware Reset or Power on Reset. Upon ent ering offset mode the capacity of the drive returned in the Identify Device data is the size of the former reserved area. A subsequent Set Max Address Command using the address returned by Read Max Address Command allows access to the entire drive. Addresses wrap so the entire drive remains addressable.

If a non-volatile reserved area has not been established before the device receives a Set Features Enable Address Offset Mode command, the command fails with Abort error status.

Disable Address Offset Mode removes the address offset and sets the size of the driv e reported by the Identify Device command back to the size specified in the last non-volatile Set Max Address command. Identify Device Word 83 bit 7.indicates the device supports the Set Features Address Offset Mode. Identify Device Word 86 bit 7 indicates the device is in address offset mode.

When B = 0, Maximum LBA/cylinder which is set by SET Max Address command will be lost by power-on or hardware reset.

B set to one is not valid when the device is in Address O ffset Mode. ABRT is set if B set to one when the device is in Address Offset mode.

Read Max Address command should be issued and completed immediately prior to issuing Set Max Address command. If the device receives Set Max Address command without a prior Read Max Address command, the device aborts the Set Max Address command. After successful completion of this command, all accesses beyond that LBA/Cylinder will be rejected with setting ID not found error. If the device r e ceives a second nonvolatile Set Max Address command (B=1) after a power on or hardware reset, the device reports an ID Not Found error.

If the maximum value to be set exceeds the capacity of the device, or the device is in the Set Max Locked or Set Max Frozen state, then the device returns command aborted.

This command requests a transfer of a single sector of data from the host. Table 6.17 defines the content of this sector of information. The password is retained by the device until t he next power cycle. When the device accepts this command the device is in Set Max Unlocked state.

Table 6.17 Set Max Password data content Word Content 0 Reserved 1- 16 Password for Set Max Security Extension 17 - 255 Reserved

This command shall not be immediately preceded by a Read Max Address command. If this command is immediately preceded by a Read Max Address command, it is interpreted as a Set Max Address command.

If the device is in the Set Max Locked or Set Max Frozen state, the device returns command aborted.

6.3.2.10.6 Set Max Lock Command [F9h, Sub 02h]

The Set Max Lock command sets the device into Set Max Locked state. After this command is completed any other Set Max commands except Set Max Unlock command and Set Max Freeze Lock command are rejected. The device remains in this state until a power cycle or the accept ance of a Set Max Unlock or Set Max Freeze Lock command.

This command shall not be immediately preceded by a Read Max Address command. If this command is immediately preceded by a Read Max Address command, it is interpreted as a Set Max Address command.

If the device is not in the Set Max Locked state, the device report s command aborted.

6.3.2.10.7 Set Max Unlock Command [F9h, Sub 03h]

This command requests a transfer of a single sector of data from the host. Table 6.17 defines the content of this sector of information. The password supplied in the sector of data transferred shall be compared with the stored Set Max password.

If the password compare fails, then the device returns command aborted and decrements the unlock counter. On the acceptance of the Set Max Lock command, this counter is set to a value of five and is decrement for each password mismatch when Set Max Unlock command is issued and the device is locked. When this counter reaches zero, then the Set Max Unlock command returns command aborted until a power cycle. If the password compare matches, then the device makes a transition to the Set Max Unlocked State and all Set Max commands shall be accepted.

This command shall not be immediately preceded by a Read Max Address command. If this command is immediately preceded by a Read Max Address command, it is interpreted as a Set Max Address command.

If the device is not in the Set Max Locked state, the device report s command aborted.

6.3.2.10.8 Set Max Unlock Command [F9h, Sub 04h]

The Set Max Freeze Lock command sets the device to Set Max Frozen state. After command completion any subsequent SET MAX commands are rejected. Commands disabled by Set Max Freeze Lock are:

• • Set Max Address command

• • Set Max Set Password command

• • Set Max Lock command

• • Set Max Unlock command

A Set Max Set Password command shall previously have been successfully completed. This command shall not be immediately preceded by a Read Max Address command. If this command is immediately preceded by a Read Max Address command, it is interpreted as a Set Max Address command.

If the device is in the Set Max Unlocked state, the device reports command aborted.

6.3.2.11 Note For Write Cache and Auto Reall ocation

(1) Loss of data in write cache Write cache is a performance enhancement whereby the device reports as completion the write commands

to the host as soon as the device has received all of the data into it s cache buffer memory. This means that there is a possibility that power off ev en after write command completion might cause the loss of the data that the device has not written onto t he media.

Therefore it is recommended that some other command except write command shall be executed before powering the device off.

(2) Error Report and Auto Write Reallocation In case of write cache mode, the device reports the writ e command completion after receiving all dat a from

host immediately. After this command completion, the device automatically reallocates the error sect or w hen the device cannot recover the error in write operation. By this auto reallocation, the unrecoverable error sector is reassigned to a spare sector, and the data of the error sector are written on the spare sect or. I f the device cannot recover the data by this auto write reallocation, the device reports the error as follows:

a) The error occurred when the command execution is on going, the error is reported for the current command. b) The error occurred when the command execution is not on going, the error is reported for by the next command.

In case of non-write cache mode, the device reports the writ e command completion after the completion of write operation on the media. If an error occurred during write operation on the media, the device automatically reallocates the error sector when the device cannot recover the error in write operation and reports the command completion.

The Auto Write Reallocation cannot be disabled. (3) Read Auto Reallocation Non recovered read errors: When a read operation fails after error recovery is fully carried out, an error is reported to the host. This error

location is registered internally as a candidate for the read reallocation. When the error location is specified as a termite of subsequent write operation, the error location is reallocated automatically .

Recovered read errors: When a read error operation for a sector failed once and recovered at the certain retry step, the recovered

sector of the data is reallocated automatically.
