4.4 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)

Note: All the above parameters contribute to drive performance. There are other parameters which contribute to the performance of the actual system. This specification defines the essential characteristics of the drive. This specification does not include the system throughput as this is dependent upon the system and the application.

The following table gives a typical value for each parameter. The detailed descriptions are found in section 5.0.

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

Weighted Average = ––––––––––––––––––––––––––––

Maximum value measured on any one drive over the full range of the environmental and voltage conditions. (See section 6.1, "Environment" on page 23 and section 6.2, "DC power requirements" on page 25)

Operating mode Description

Spin-Up Start up time period from spindle stop or power down.

Seek Seek operation mode

Write Write operation mode

Read Read operation mode

Performance The device is capable of responding immediately to idle media access requests.

All electronic components remain powered and the full frequency servo remains operational.

Active idle The device is capable of responding immediately to media access requests.

Some circuitry—including servo system and R/W electronics—is in power saving mode. The head is parked near the mid-diameter the disk without servoing. A device in Active idle mode may take longer to complete the execution of a command because it must activate that circuitry.

Low power idle The head is unloaded onto the ramp position.

The spindle motor is rotating at full speed.

Standby The device interface is capable of accepting commands.

The spindle motor is stopped. All circuitry but the host interface is in power saving mode. The execution of commands is delayed until the spindle becomes ready.

Sleep The device requires a soft reset or a hard reset to be activated.

All electronics, including spindle motor and host interface, are shut off.

4.4.3.2 Operating mode at power on

The device goes into Idle mode after power on or hard reset as an initial state. Initial state may be changed to Standby mode using pin C on the interface connector. Refer to section 7.10 on page 58, "Drive address setting" for details.

4.4.3.3 Adaptive power save control

The transient timing from Performance Idle mode to Active Idle mode and Active Idle mode to Low Power Idle mode is controlled adaptively according to the access pattern of the host system. The transient timing from Low Power Idle mode to Standby mode is also controlled adaptively, if it is allowed by Set Features Enable Advanced Power Management subcommand.

5.0 Data integrity

5.1 Data loss on power off

! Data loss will not be caused by a power off during any operation except the write operation.

! A power off during a write operation causes the loss of any received or resident data that has not

been written onto the disk media.

! A power off during a write operation might make a maximum of one sector of data unreadable. This

state can be recovered by a rewrite operation.

5.2 Write Cache

When the write cache is enabled, the write command may complete before the actual disk write operation finishes. This means that a power off, even after the write command completion, could cause the loss of data that the drive has received but not yet written onto the disk.

In order to prevent this data loss, confirm the completion of the actual write operation prior to the power off by issuing a

! Soft reset

! Hard reset

! Flush Cache command

! Standby command

! Standby Immediate command

! Sleep command

Confirm the command’s completion.

5.3 Equipment status

The equipment status is available to the host system any time the drive is not ready to read, write, or seek. This status normally exists at the power-on time and will be maintained until the following conditions are satisfied:

! The access recalibration/tuning is complete.

! The spindle speed meets the requirements for reliable operation.

! The self-check of the drive is complete.

The appropriate error status is made available to the host system if any of the following conditions occur after the drive has become ready:

! The spindle speed lies outside the requirements for reliable operation.

! The occurrence of a Write Fault condition.

Travelstar 60GH & 40GN hard disk drive specifications

5.4 WRITE safety

The drive ensures that the data is written into the disk media properly. The following conditions are monitored during a write operation. When one of these conditions exceeds the criteria, the write operation is terminated and the automatic retry sequence is invoked.

! Head off track

! External shock

! Low supply voltage

! Spindle speed out of tolerance

! Head open/short

5.5 Data buffer test

The data buffer is tested at power on reset and when a drive self-test is requested by the host. The test consists of a write/read '00'x and 'ff'x pattern on all buffers.

5.6 Error recovery

Errors occurring on the drive are handled by the error recovery procedure.

Errors that are uncorrectable after application of the error recovery procedure are reported to the host system as nonrecoverable errors.

5.7 Automatic reallocation

The sectors that show some errors may be reallocated automatically when specific conditions are met. The drive does not report any auto reallocation to the host system. The conditions for auto reallocation are described below.

5.7.1 Nonrecovered write errors

When a write operation cannot be completed after the Error Recovery Procedure (ERP) is fully carried out, the sectors 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 has failed.

5.7.2 Nonrecoverable read error

When a read operation fails after 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 required criteria, this sector is reallocated.

5.7.3 Recovered read errors

When a read operation for a sector fails and is recovered at the specific ERP step, the sector is reallocated automatically. A media verification sequence may be run prior to the reallocation according to the predefined conditions.

Travelstar 60GH & 40GN hard disk drive specifications

5.8 ECC

The 40 byte three interleaved ECC processor provides user data verification and correction capability. The first 4 bytes of ECC are check bytes for user data and the other 36 bytes are Read Solomon ECC. Each interleave has 12 bytes for ECC. Hardware logic corrects up to 15 bytes (5 bytes for each interleave) errors on-the-fly.

Following are some examples of error cases. An "O" means that the byte contains no error. An "X" means that at least one bit of the byte is bad.

6.4 Reliability

6.4.1 Data reliability

! Probability of not recovering data is 1 in 10

! ECC implementation

On-the-fly correction performed as a part of read channel function recovers up to 15 symbols of error in 1 sector (1 symbol is 8 bits).

6.4.2 Failure prediction (S.M.A.R.T.)

The drive supports Self-monitoring, analysis and reporting technology (S.M.A.R.T.) function. The details are described in section 11.8, "S.M.A.R.T. Function" on page 84 and 13.32, "S.M.A.R.T. Function Set (B0h)" on page 165.

6.4.3 Cable noise interference

To avoid any degradation of performance throughput or error 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.

6.4.4 Service life and usage condition

The drive is designed to be used under the following conditions:

! The drive should be operated within specifications of shock, vibration, temperature, humidity, altitude,

and magnetic field.

! The drive should be protected from ESD.

! The breathing hole in the top cover of the drive should not be covered.

! Force should not be applied to the cover of the drive.

! The specified power requirements of the drive should be satisfied.

! The drive frame should be grounded electrically to the system through four screws.

! The drive should be mounted with the recommended screw depth and torque.

! The interface physical and electrical requirements of the drive should satisfy ATA-5.

! The power-off sequence of the drive should comply with the 6.4.6.2, "Required power-off sequence.”

Service life of the drive is approximately 5 years or 20,000 power on hours, whichever comes first, under the following assumptions:

! Less than 333 power on hours per month.

! Seeking/Writing/Reading operation is less than 20% of power on hours.

This does not represent any warranty or warranty period. Applicable warranty and warranty period are covered by the purchase agreement.

Travelstar 60GH & 40GN hard disk drive specifications

6.4.5 Preventive maintenance

None.

6.4.6 Load/unload

The product supports a minimum of 300,000 normal load/unloads.

Load/unload is a functional mechanism of the hard disk drive. It is controlled by the drive micro code. Specifically, unloading of the heads is invoked by the following commands:

! Hard reset

! Standby

! Standby immediate

! Sleep

Load/unload is also invoked as one of the idle modes of the drive.

The specified start/stop life of the product assumes that load/unload is operated normally, not in emergency mode.

6.4.6.1 Emergency unload

When hard disk drive power is interrupted while the heads are still loaded the micro code cannot operate and the normal 5-volt power is unavailable to unload the heads. In this case, normal unload is not possible. The heads are unloaded by routing the back EMF of the spinning motor to the voice coil. The actuator velocity is greater than the normal case and the unload process is inherently less controllable without a normal seek current profile.

Emergency unload is intended to be invoked in rare situations. Because this operation is inherently uncontrolled, it is more mechanically stressful than a normal unload.

The drive supports a minimum of 20,000 emergency unloads.

6.4.6.2 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. Refer to section 14.0, "Time-out values," on page 195.

! Step 3: Terminate power to HDD.

Travelstar 60GH & 40GN hard disk drive specifications

This power-down sequence should be followed for entry into any system power-down state, system suspend state, or system hibernation state. In a robustly designed system, emergency unload is limited to rare scenarios, such as battery removal during operation.

6.4.6.3 Power switch design considerations

In systems that use the Travelstar 60GH & 40GN consideration should be given to the design of the system power switch.

IBM recommends that the switch operate under control of the BIOS, as opposed to being hardwired. The same recommendation is made for cover-close switches. When a hardwired switch is turned off, emergency unload occurs, as well as the problems cited in section 5.1, "Data loss by power off" on page 19 and section 5.2, “Write Cache” on page 19.

6.4.6.4 Test considerations

Start/stop testing is classically performed to verify head/disk durability. The heads do not land on the disk, so this type of test should be viewed as a test of the load/unload function.

Start/Stop testing should be done by commands through the interface, not Simple power cycling of the drive invokes the emergency unload mechanism and subjects the HDD to nontypical mechanical stress.

Power cycling testing may be required to test the boot-up function of the system. In this case IBM recommends that the power-off portion of the cycle contain the sequence specified in section 6.4.6.2, "Required Power-Off Sequence” on page 29. If this is not done, the emergency unload function is invoked and nontypical stress results.

Figure 35. Signal definition

The signal lines marked with (*) are redefined during the Ultra DMA protocol to provide special functions. These lines change from the conventional to special definitions at the moment the host decides to allow a DMA burst, if the Ultra DMA transfer mode was previously chosen via SetFeatures. The drive becomes aware of this change upon assertion of the DMACK- line. These lines revert back to their original definitions upon the deassertion of DMACK- at the termination of the DMA burst.

7.4 Signal descriptions

DD00–DD15

A 16-bit bi-directional data bus between the host and the drive. The lower 8 lines, DD00-07, are used for Register and ECC access. All 16 lines, DD00–15, are used for data transfer. These are 3-state lines with 24 mA current sink capability.

DA00–DA02

These are addresses used to select the individual register in the drive.

CS0-

The chip select signal generated from the Host address bus. When active, one of the Command Block Registers [Data, Error (Features when written), Sector Count, Sector Number, Cylinder Low, Cylinder High, Drive/Head and Status (Command when written) register] can be selected.

CS1-

The chip select signal generated from the Host address bus. When active, one of the Control Block Registers [Alternate Status (Device Control when written) and Drive Address register] can be selected.

RESET-

This line is used to reset the drive. It shall be kept at a Low logic state during power up and kept High thereafter.

DIOW-

The rising edge of this signal holds data from the data bus to a register or data register of the drive.

DIOR-

When this signal is low, it enables data from a register or data register of the drive onto the data bus. The data on the bus shall be latched on the rising edge of DIOR-.

INTRQ

The interrupt is enabled only when the drive is selected and the host activates the -IEN bit in the Device Control Register. Otherwise, this signal is in high impedance state regardless of the state of the IRQ bit. The interrupt is set when the IRQ bit is set by the drive CPU. The IRQ is reset to zero by a host read of the status register or a write to the Command Register. This signal is a 3-state line with 24 mA of sink capability.

IOCS16-

A signal indicating to the host that a 16-bit wide data register has been addressed and that the drive is prepared to send or receive a 16-bit wide data word. This signal is an Open-Drain output with 24 mA sink capability and an external resistor is needed to pull this line to 5 volts.

DASP-

This is a time-multiplexed signal which indicates that a drive is active or that device 1 is present. This signal is driven by an Open-Drain driver and internally pulled up to 5 volts through a 10 kΩ resistor. During a Power-On initialization or after RESET- is negated, DASP- shall be asserted by Device 1 within 400 ms to indicate that device 1 is present. Device 0 shall allow up to 450 ms for device 1 to assert DASP-. If device 1 is not present, device 0 may assert DASP- to drive an LED indicator. The DASP- signal shall be negated following acceptance of the first valid command by device 1. Anytime after negation of DASP-, either drive may assert DASP- to indicate that a drive is active.

Travelstar 60GH & 40GN hard disk drive specifications

PDIAG-

This signal shall be asserted by device 1 to indicate to device 0 that it has completed the diagnostics. This line is pulled up to 5 volts in the drive through a 10 kΩ resistor.

Following a Power On Reset, software reset, or RESET-, drive 1 shall negate PDIAG- within 1 ms (to indicate to device 0 that it is busy). Drive 1 shall then assert PDIAG- within 30 seconds to indicate that it is no longer busy and is able to provide status.

Following the receipt of a valid Execute Drive Diagnostics command, device 1 shall negate PDIAGwithin 1 ms to indicate to device 0 that it is busy and has not yet passed its drive diagnostics. If device 1 is present then device 0 shall wait up to 6 seconds from the receipt of a valid Execute Drive Diagnostics command for drive 1 to assert PDIAG-. Device 1 should clear BSY before asserting PDIAG-, as PDIAG- is used to indicate that device 1 has passed its diagnostics and is ready to post status. If DASP- was not asserted by device 1 during reset initialization, device 0 shall post its own status immediately after it completes diagnostics and clears the device 1 Status register to 00h. Device 0 may be unable to accept commands until it has finished its reset procedure and is ready (DRDY=1).

CSEL (Cable Select)

This signal is monitored to determine the drive address (master or slave) when the jumper on the interface connector is at Position-3.

When CSEL is at ground or is at a low level, the drive works as a Master. If CSEL is open or is at a logical high level, the drive works as a Slave.

The signal level of CSEL to one drive should be different from the signal level to another drive on the same AT interface cable to avoid master-master or slave-slave configurations.

KEY

Pin position 20 has no connection pin. It is recommended to close the respective position of the cable connector in order to avoid incorrect insertion.

IORDY

This signal is an indication to the host that the drive is ready to complete the current I/O cycle. This line is driven low at the falling edge of DIOR- or DIOW- when the drive needs some additional WAIT cycle(s) to extend the PIO cycle. This line can be connected to the host IORDY signal in order to insert a WAIT state(s) into the host PIO cycle. This signal is an Open-Drain output with 24 mA sink capability.

5V Power

There are two input pins for the +5 V power supply. One is the "+5 V Logic" input pin and the second is the "+5 V Motor" input pin. These two input pins are tied together within the drive.

DMACK-

This signal shall be used by the host in response to DMARQ to either acknowledge that data has been accepted, or that data is available.

This signal is internally pulled up to 5 Volt through a 15 kΩ resistor with a resistor tolerance value of –50% to +100%.

DMARQ

This signal is used for DMA data transfers between the host and drive. It shall be asserted by the drive when it is ready to transfer data to or from the host. The direction of data transfer is controlled by

-HIOR and -HIOW signals. This signal is used in a handshake mode with DMACK-. This signal is a 3-state line with 24 mA sink capability and internally pulled down to GND through a 10 kΩ resistor.

Travelstar 60GH & 40GN hard disk drive specifications

HDMARDY- (Ultra DMA)

This signal is used only for Ultra DMA data transfers between host and drive.

The signal HDMARDY- is a flow control signal for Ultra DMA data in bursts. This signal is held asserted by the host to indicate to the device that the host is ready to receive Ultra DMA data in transfers. The host may negate HDMARDY- to pause an Ultra DMA data in transfer.

HSTROBE (Ultra DMA)

This signal is used only for Ultra DMA data transfers between host and drive.

The signal HSTROBE is the data out strobe signal from the host for an Ultra DMA data out transfer. Both the rising and falling edge of HSTROBE latch the data from DD (15:0) into the device. The host may stop toggling HSTROBE to pause an Ultra DMA data out transfer.

7.10 Drive address setting

A jumper placed on the interface connector determines the drive address. The three drive addresses are shown below.

Figure 48. Drive address setting

Setting 1—Device 0 (Master) (no jumper is used) Setting 2—Device 1 (Slave) Setting 3—Cable Select Setting 4—Never attach a jumper here Setting 5—Never attach a jumper here

When pin C is grounded, the drive does not spin up at POR.

When the drive address is Cable Select, the address depends on the condition of pin 28 of the AT interface cable. If pin 28 is ground (or low), the drive is a Master. If pin 28 is open (or logic high), the drive is a Slave.

7.10.1 Drive default address setting

The default setting of jumper at shipment is Setting 1: no jumper.

Travelstar 60GH & 40GN hard disk drive specifications

7.11 Addressing of HDD registers

The host addresses the drive through a set of registers called a Task File. These registers are mapped into the host's I/O space. Two chip select lines (CS0- and CS1-) and three address lines (DA00–02) are used to select one of these registers, while a DIOR- or DIOW- is provided at the specified time.

The chip select line CS0- is used to address the Command Block registers while the CS1- is used to address Control Block registers.

The following table shows the I/ O address map.

8.0 General

8.1 Introduction

This specification describes the host interface of the Travelstar 60GH & 40GN.

The interface conforms to the Working Document of Information technology, AT Attachment with Packet Interface Extension (ATA/ATAPI-5) Revision 3, dated 29 February 2000, with certain limitations described in section 9.0, "Deviations From Standard” on page 65.

The drive supports the following new functions included by ATA/ATAPI-5 standards or newer standards:

! Device Configuration Overlay

The drive supports the following functions as Vendor Specific Functions:

! Address Offset Feature ! Format Unit Function ! ENABLE/DISABLE DELAYED WRITE ! SENSE CONDITION command

9.0 Deviations from standard

The device conforms to the referenced specifications, with deviations described below.

The interface conforms to the Working Document of Information Technology, AT Attachment with Packet Interface Extension (ATA/ATAPI-5) Revision 3, dated 29 February 2000, with the following deviation:

Standby Timer

Write Verify

S.M.A.R.T. Return Status

Standby timer is enabled by STANDBY command or IDLE command. The value in the Sector Count register shall be used to determine the time programmed into the Standby timer. If the Sector Count register is zero, the Standby timer is automatically set to 109 minutes.

WRITE VERIFY command does not include read verification after write operation. The function is the same as WRITE SECTORS command.

S.M.A.R.T. RETURN STATUS subcommand does not check advisory attributes. This means that the device will not report a threshold exceeded condition unless the prefailure attributes exceed their corresponding thresholds. For example, a Power-On Hours Attribute never results in a negativ reliability status.

Figure 50. Register Set

Communication to or from the device is through an I/O Register that routes the input or output data to or from the registers addressed by the signals from the host (CS0-, CS1-, DA2, DA1, DA0, DIOR- and DIOW-).

The Command Block Registers are used for sending commands to the device or posting status from the device.

The Control Block Registers are used for device control and to post alternate status.

Travelstar 60GH & 40GN hard disk drive specifications

10.1 Alternate Status Register

Alternate Status Register

01234567

ERRIDXCORDRQDSCDFRDYBSY

Figure 51. Alternate Status Register

This register contains the same information as the Status Register. The only difference between this register and the Status Register is that reading the Alternate Status Register does not imply an interrupt acknowledge or a clear of a pending interrupt. See 10.13, "Status Register" on page 72 for the definition of the bits in this register.

10.2 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 Figure 72 on page 107. All other registers required for the command must be set up before writing to the Command Register.

10.3 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.

The cylinder number may be from zero to the number of cylinders minus one.

10.4 Cylinder Low Register

This register contains the low order 8 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 (1).

Travelstar 60GH & 40GN hard disk drive specifications

10.5 Data Register

This register is used to transfer data blocks between the device data buffer and the host. It is also the register through which sector information is transferred on a Format Track command and the configuration information is transferred on an Identify Device command.

All data transfers are 16 bits wide, except for ECC byte transfers, which are 8 bits wide. Data transfers are PIO only.

The register contains valid data only when DRQ = 1 is in the Status Register.

IDNF (IDN)

ABRT (ABT)

TK0NF (T0N)

AMNF (AMN)

Interface CRC Error. When CRC = 1, it indicates that a CRC error has occurred on the data bus during a Ultra DMA transfer.

Uncorrectable Data Error. When UNC = 1 it indicates that an uncorrectable data error has been encountered.

ID Not Found. When IDN = 1, it indicates that the requested sector's ID field could not b found.

Aborted Command. When ABT = 1, it indicates that the requested command has been aborted due to a device status error or an invalid parameter in an output register.

Track 0 Not Found. When T0N = 1, it indicates that track 0 was not found during a Recalibrate command.

Address Mark Not Found. When AMN = 1, it indicates that the data address mark has not been found after finding the correct ID field for the requested sector.

10.10 Features Register

This register is command specific. This register is used with the Set Features command, the S.M.A.R.T. Function Set command, and the Format Unit command.

10.11 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 is specified.

If the register is zero at command completion, the command was successful. If it is not successfully completed, the register contains the number of sectors which need to be transferred in order to complete the request.

The contents of the register are defined differently on some commands. These definitions are given in section 13.0, “Command descriptions” on 107.

Travelstar 60GH & 40GN hard disk drive specifications

10.12 Sector Number Register

This register contains the starting sector number for any disk data access for the subsequent command. The sector number is from one to the maximum number of sectors per track.

In LBA mode, this register contains Bits 0–7. At the end of the command, this register is updated to reflect the current LBA Bits 0–7.

10.13 Status Register

Status Register

01234567

ERRIDXCORDRQDSCDFDRDYBSY

Figure 56. 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.

Bit Definitions BSY

DRDY (RDY)

DSC

DRQ

IDX

ERR

Busy. Bit 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.

Device Ready. When bit RDY=1 it indicates that the device is capable of responding to a command. Bit RDY will be set to 0 during power on until the device is ready to accept a command.

Device Fault. It DF=1 it indicates that the device has detected a write fault condition. Bit DF is set to 0 after the Status Register is read by the host.

Device Seek Complete. If DSC=1, it indicates that a Seek has completed and the device head is settled over a track. Bit 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 hos and at that 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 the drive not spinning up.

Data Request. Bit 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.

Corrected Data. Always 0.CORR (COR) Index. Bit IDX=1 once per revolution. Since IDX=1, only for a very short time during eac

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 bit for timing purposes. Error. Bit 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 bit ERR=0 when the next command is received from the host.

ATA has the following three types of resets:

Power On Reset (POR)

Hard Reset (Hardware Reset)

Soft Reset (Software Reset)

The actions of each reset are shown in Figure 57 on page 74.

The device executes a series of electrical circuitry diagnostics, spins up the head disk assembly, tests speed and other mechanical parametric, and sets default values.

The RESET signal is negated in the ATA Bus. The device resets the interface circuitry and sets the default values.

The SRST bit in the Device Control Register is set and then is reset. The device resets the interface circuitry according to the Set Features require ment.

11.3 Diagnostic and Reset considerations

The Set Max password, the Set Max security mode and the Set Max unlock counter are not retained over a Power On Reset but are retained over a Hard Reset or Soft Reset.

For each Reset and Execute Device Diagnostic, the diagnostic is done as follows:

Power On Reset, Hard Reset

Soft Reset

Execute Device Diagnostic

In each case – Power On Reset [Hard Reset], Soft Reset, and the Execute Device Diagnostic com- mand – the Device 0 Error register value is interpreted using the table below.

DASP- is read by Device 0 to determine if Device 1 is present. If Device 1 is present Device 0 shall read PDIAG- to determine when it is valid to clear the BSY bit and whether Device 1 has powered on or reset without error, otherwise Device 0 clears the BSY bit whenever it is ready to accept commands. Device 0 may asser DASP- to indicate device activity. If Device 1 is not present, Device 0 does not Assert DASP- at POR.

If Device 1 is present, Device 0 shall read PDIAG- to determine when it is valid to clear the BSY bit and whether Device 1 has reset without any errors; otherwise, Device 0 shall simply reset and clear the BSY bit. DASP- is asserted by Device 0 (and Device 1 if it is present) in order to indicate device active.

If Device 1 is present, Device 0 shall read PDIAG- to determine when it is valid to clear the BSY bit and if Device 1 passed or failed the EXECUTE DEVICE DIAGNOSTIC command; otherwise, Device 0 shall simply execute its diagnostics and then clear the BSY bit. DASP- is asserted by Device 0 (and Device 1 if it is present) in order to indicate that the device is active.

11.4 Power-off considerations

11.4.1 Load/Unload

Load/Unload is a functional mechanism of the hard disk drive. It is controlled by the drive microcode. Specifically, unloading of the heads is invoked by the following commands.

ResponseCommand

UL -> Comp.Standby

UL -> Comp.Standby Immediate

UL -> Comp.Sleep

ResponseReset

Rdy (*1)Soft Reset

UL -> RdyHard Reset

= unloadUL = completeComp = interface readyRdy Load/Unload condition is not changed by Soft Reset(*1)

Figure 61. Device behavior by ATA commands.

Load/unload is also invoked as one of the idle modes of the drive.

The specified start/stop life of the product assumes that load/unload is operated normally, NOT in emergency mode.

11.4.2 Emergency unload

When the drive power is interrupted with the heads still loaded, the microcode cannot operate and the normal 5V power is unavailable to unload the heads. In this case, normal unload is not possible, so the heads are unloaded by routing the back EMF of the spinning motor to the voice coil. The actuator velocity is greater than the normal case, and the unload process is inherently less controllable without a normal seek current profile.

Emergency unload is intended to be invoked in rare situations. Because this operation is inherently uncontrolled, it is more mechanically stressful than a normal unload.

A single emergency unload operation is more stressful than 100 normal unloads. Use of emergency unload reduces the start/stop life of the drive at a rate at least 100 times faster than that of normal unload and may damage the drive.

Travelstar 60GH & 40GN hard disk drive specifications

11.4.3 Required power-off sequence

When power is removed on most drives at an arbitrary time, problems can result. The followoing are examples of such problems:

! Data is lost from the write buffer ! If the drive is writing a sector, a partially-written sector with an incorrect ECC block results, the

sector contents are destroyed, and reading that sector results in a hard error

! Heads may land in the data zone instead of the landing zone depending on the design of the drive

You may then turn off the drive in the following order:

1. Issue Standby Immediate or sleep command

2. Wait until COMMAND COMPLETE STATUS is returned. (It may take up to 350 ms in a typical case.)

3. Terminate power to drive

11.5 Sector Addressing Mode

All addressing of data sectors recorded on the device's media is done by a logical sector address. The logical CHS address for the drive is different from the actual physical CHS location of the data sector on the disk media.

The drive supports 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. A host system must set the L bit to 1 if the host uses LBA Addressing mode.

11.5.1 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 cannot exceed 255 (0FFh). Heads are numbered from 0 to the maximum value allowed by the current CHS translation mode but cannot 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.

Travelstar 60GH & 40GN hard disk drive specifications

11.5.2 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 formula is always true:

LBA = ((cylinder x heads_per_cylinder + heads) x 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:

<- - - LBA bits 27–24Device/Head

<- - - LBA bits 23–16Cylinder High

<- - - LBA bits 15–8Cylinder Low

<- - - LBA bits 7–0Sector Number

11.6 Power management features

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.

The drive implements 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

11.6.1 Power Mode

Sleep Mode

Standby Mode

Active 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.

The device interface is capable of accepting commands, but since the media may not be immediately accessible, there is a delay while waiting for the spindle to reach operating speed.

Refer to 11.7, "Adaptive Battery Life Extender (ABLE-3) feature" on page 82.Idle Mode

The device is in execution of a command or accessing the disk media with the read look-ahead function or the write cache function.

11.6.2 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 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.

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.

11.6.3 Standby/Sleep command completion timing

1. Confirm the completion of writing cached data in the buffer to media.

2. Unload the heads on the ramp.

3. Set the DRDY bit and the DSC bit in Status Register.

4. Set the INTRQ (completion of the command).

5. Activate the spindle break to stop the spindle motor.

6. Wait until the spindle motor is stopped.

7. Perform the post process.

Travelstar 60GH & 40GN hard disk drive specifications

11.6.4 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 the SECTOR COUNT register on Idle command or the Standby command is set to "00h", the device will automatically set the standby timer to 109 minutes.

11.6.5 Status

In the active, idle, and standby modes, the device shall have the RDY bit of the status register set. If the BSY bit is not set, the device shall be ready to accept any command.

In sleep mode, the device's interface is not active. A host shall not attempt to read the status of the device or issue commands to the device.

11.6.6 Interface Capability for Power Modes

Each power mode affects the physical interface as defined in the following table:

RDYBSYMode

Figure 62. 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.

The interface is inactive in sleep mode, but the access to the interface registers and the validity of INTRQ is guaranteed for two seconds after the Sleep command is completed. After this period, the contents of interface registers may be lost. Since the contents of interface registers may be invalid, the host should NOT check the Status register nor the Alternate Status register prior to issuing a soft reset to wake up a device.

11.6.7 Initial Power Mode at Power On

After power on or hard reset the device goes to IDLE mode or STANDBY mode depending on the option. Refer to section 4.4.3, "Operating Modes" on page 17 for the initial power mode selection.

Travelstar 60GH & 40GN hard disk drive specifications

11.7 Advanced Power Management (ABLE-3) feature

This feature provides power saving without performance degradation. The Adaptive Battery Life Extender 3 (ABLE-3) technology intelligently manages transition among power modes within the device by monitoring access patterns of the host.

This technology has three idle modes; Performance Idle mode, Active Idle mode, and Low Power Idle mode.

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:

! A SET FEATURES subcommand to enable Advanced Power Management

! A SET FEATURES subcommand to disable Advanced Power Management

The Advanced Power Management feature is independent of the Standby timer setting. If both Advanced Power Management level 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 it is time to enter the Standby state.

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.

11.7.1 Performance Idle Mode

This mode is usually entered immediately after Active mode command processing is complete, instead of conventional idle mode. In Performance Idle mode, all electronic components remain powered and full frequency servo remains operational. This provides instantaneous response to the next command. The duration of this mode is intelligently managed as described below.

11.7.2 Active Idle Mode

In this mode, power consumption is 45–55% less than that of Performance Idle mode. Additional electronics are powered off and the head is parked near the mid-diameter of the disk without servoing. Recovery time to Active mode is about 20 ms.

11.7.3 Low Power Idle Mode

Power consumption is 60–65% less than that of Performance Idle mode. The heads are unloaded on the ramp but the spindle is still rotated at the full speed. Recovery time to Active mode is about 300 ms.

11.7.4 Transition Time

The transition time is dynamically managed by the user's recent access pattern, instead of fixed times. The ABLE-3 algorithm monitors the interval between commands instead of the command frequency of ABLE-2. The algorithm supposes that the next command will come with the same command interval

Travelstar 60GH & 40GN hard disk drive specifications

distribution as the previous access pattern. The algorithm calculates the expected average saving energy and response delay for next command in several transition time case based on this assumption. And it selects the most effective transition time with the condition that the calculated response delay is shorter than the value calculated from the specified level by Set Feature Enable Advanced Power Management command.

The optimal time to enter Active Idle mode is variable depending on the recent behavior of the user. It is not possible to achieve the same level of Power savings with a fixed entry time into Active Idle because every user’s data and access pattern is different. The optimum entry time changes over time.

The same algorithm works for entering into Low Power Idle mode and Standby mode, which consumes less power but needs more recovery time switching from this mode to Active mode.

11.8 S.M.A.R.T. Function

The intent of Self-monitoring, analysis, and reporting technology (S.M.A.R.T.) 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, S.M.A.R.T. 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.

Since S.M.A.R.T. utilizes the internal device microprocessor and other device resources, there may be some small overhead associated with its operation. However, special care has been taken in the design of the S.M.A.R.T. algorithms to minimize the impact to host system performance. Actual impact of S.M.A.R.T. overhead is dependent on the specific device design and the usage patterns of the host system. To further ensure minimal impact to the user, S.M.A.R.T. capable devices are shipped from the device manufacturer's factory with the S.M.A.R.T. feature disabled. S.M.A.R.T. capable devices can be enabled by the system OEMs at time of system integration or in the field by after-market products.

11.8.1 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.

11.8.2 Attribute values

Attribute values are used to represent the relative reliability of individual performance or calibration attributes. Higher attribute values indicate that the analysis algorithms 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 predicting a higher probability of a degrading or fault condition existing. There is no implied linear reliability relationship corresponding to the numerical relationship between different attribute values for any particular attribute.

11.8.3 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 value 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.

11.8.4 Threshold exceeded condition

If one or more attribute values are less than or equal to their corresponding attribute thresholds, then the device reliability status is negative, indicating an impending degrading or faulty condition.

11.8.5 S.M.A.R.T. commands

The S.M.A.R.T. commands provide access to attribute values, attribute thresholds and other logging and reporting information.

Travelstar 60GH & 40GN hard disk drive specifications

11.8.6 S.M.A.R.T. operation with power management modes

The device saves attribute values automatically on every head unload timing except the emergency unload, even if the attribute auto save feature is not enabled. The head unload is done not only by Standby, Standby Immediate, or Sleep command or Hard Reset, but also by the automatic power saving functions like ABLE-3 or Standby timer. So basically it is not necessary for a host system to enable the attribute auto save feature, when it utilizes the power management. If the attribute auto save feature is enabled, attribute values will be saved after 30minutes passed since the last saving, besides above condition.

Travelstar 60GH & 40GN hard disk drive specifications

11.9 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 a device even if it is removed from the computer.

New commands are supported for this feature as listed below:

('F1'h)Security Set Password ('F2'h)Security Unlock ('F3'h)Security Erase Prepare ('F4'h)Security Erase Unit ('F5'h)Security Freeze Lock ('F6'h)Security Disable Password

11.9.1 Security Mode

The following security modes are provided.

Device Locked Mode

Device Unlocked Mode

Device Frozen Mode

The device disables media access commands after power on. Media access commands are enabled by either a Security Unlock command or a Security Erase Unit command.

The device enables all commands. If a password is not set this mode is entered after power on, otherwise it is entered by a Security Unlock or a Security Erase Unit command.

The device enables all commands except those which can update the device lock function, set/change password. The device enters this mode via a Security Freeze Lock command. It cannot quit this mode until power off.

11.9.2 Security level

The following security levels are provided:

High level security

Maximum level security

When the device lock function is enabled and the User Password is forgotten, the device can be unlocked via a Master Password.

When the device lock function is enabled and the User Password is forgotten, then only the Master Password with a Security Erase Unit command can unlock the device. Then user data is erased.

11.9.3 Password

This function can have two types of passwords as described below.

Master Password

User Password

The system manufacturer or dealer who intends to enable the device lock function for end users must set the master password even if only single level password protection is required. Otherwise, the 'default' master password which is set by IBM can unlock a device that is locked with a user password.

When the Master Password is set, the device does NOT enable the Device Lock Function, and the device CANNOT be locked with the Master Password, but the Master Password can be used for unlocking the locked device.

The User Password should be given or changed by a system user. When the User Password is set, the device enables the Device Lock Function, and then the device is locked on the next power on reset or hard reset.

Travelstar 60GH & 40GN hard disk drive specifications

11.9.4 Master Password Revision Code

This Master Password Revision Code is set by Security Set Password command with the master password. And this revision code field is returned in the Identify Device command word 92. The valid revision codes are 0001h to FFFEh. The default value of Master Password Revision Code is FFFEh. Values 0000h and FFFFh are reserved.

11.9.5 Operation example

11.9.5.1 Master Password setting

The system manufacturer or dealer can set an initial Master Password using the Security Set Password command, without enabling the Device Lock Function.
