3.0 Fixed disk subsystem description

)

3.1 Control Electronics

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

Controls and interprets all interface signals between the host controller and the drive

Controls read write accessing of the disk media, including defect management and error recovery

Controls starting, stopping, and monitoring of the spindle

Conducts a power-up sequence and calibrates the servo

Analyzes servo signals to provide closed loop control. These include position error signal and estimated velocity

Monitors the actuator position and determines the target track for a seek operation

Controls the voice coil motor driver to align the actuator in a desired position

Constantly monitors error conditions of the servo and takes corresponding action if an error occurs

Monitors various timers such as head settle and servo failure

Performs self-checkout (diagnostics

3.2 Head disk assembly

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

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

3.3 Actuator

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

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

the disk where it is parked.

4.3 Performance Characteristics

A file 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 file performance. There are other parameters that contribute to the performance of the actual system. This specification tries to define the bare file characteristics, not the system throughput which will depends on the system and the application.

4.3.1 Command Overhead

Command Overhead is defined as described in the following table.

Typical.

The average of the drive population tested at nominal environmental and

voltage conditions.

Maximum or Max.

The maximum value measured on any one drive over the full range of the environmental and voltage conditions. (See Sections 9.2 "Environment" on page 47 and 9.3 "DC Power Requirements" on page 48.)

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

24.6Instantaneous (Typical)

19.5Sustained (read Typical)

Figure 11. Data Transfer Speed

Instantaneous Disk-Buffer Transfer Rate (Mbyte/sec) is derived by:

(Number of Sectors on a track) * 512 * (Revolution/sec)

Note: Number of sectors per track will vary because of the linear density recording.

Sustained Disk-Buffer Transfer Rate (Mbyte/sec) is defined by considering head/cylinder change time for read operation. This gives a local average data transfer rate. It is derived by:

(Sustained Transfer Rate) = A/(B + C + D)

A = (Number of Data Sectors per Cylinder) * 512 B = (# of Surface per cylinder) - 1) * (Head Switch Time) C = (Cylinder Change Time) D = (# of Surface) * (One Revolution Time)

100

Instantaneous Buffer-Host Transfer Rate (Mbyte/sec) defines the maximum data transfer rate on AT Bus. It also depends on the speed of the host.

The measurement method is given in section 4.3.6 "Throughput" on page 13.

4.3.5 Buffering Operation (Look ahead/Write cache)

To improve the total performance, the file utilizes a ring buffer for look ahead and write cache. The total of 1916 KB of the buffer is divided into multiple segmented blocks for write buffer or read buffer use.

5.0 Defect flagging strategy

Media defects are remapped to the next available sector during the Format Process in manufacturing. The mapping from LBA to the physical locations is calculated by an internally maintained table.

Shipped format

Data areas are optimally used.

No extra sector is wasted as a spare throughout user data areas.

All pushes generated by defects are absorbed by spare tracks of inner zone.

N N+1 N+2 N+3

Figure 16. PList physical format

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

Note: It is possible to reallocate sectors during drive usage including sectors damaged during the early period of usage. Reallocation of sectors is primarily caused by handling problems and is a normal maintenance function performed by the hard disk drive.

6.0 Data integrity

6.1 Data loss at Power off

The drive retains recorded information under all non-write operations.

No more than one sector can be lost by power down during write operation while write cache is disabled.

Power off during write operations may make an incomplete sector which will report hard data error when read. The sector can be recovered by a rewrite operation.

Hard reset does not cause any data loss.

If the write cache option is active, the data in the write cache will be lost. To prevent the loss of customer data, it is recommended that the last write access before power off be issued after setting write cache to off.

6.2 Write cache

Power off while write cache is enabled may cause the loss of data remaining in the cache that has not been flushed onto the disk media. Therefore, it is possible for data to be lost due to a power off after write command completion.

There are two ways to check if all data in the write cache has been flushed onto the disk. Checking just before power off is recommended to prevent data loss.

- Confirm successful completion of Software Reset

- Confirm successful completion of Flush Cache command

6.3 Equipment status

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 power-on time and will be maintained until the following conditions are satisfied:

Access recalibration/tuning is complete

Spindle speed meets requirements for reliable operation

Self-check of drive is complete

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

Spindle speed outside requirements for reliable operation

Occurrence of a WRITE FAULT condition

CS1- is 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. (See Figure 39 on page 43.)

This signal is used to reset the drive. The drive requires that this line be kept at a logic Low state during power up and in a High state thereafter.

This signals rising edge holds data from the host data bus to a register or data register of the HDD.

When the DIOR- signal is low data is enabled from either a register or data register of the drive onto the data bus. The data on the bus is latched on the rising edge of the DIORsignal.

The interrupt request is enabled only when the drive is selected and the host activates the nIEN bit in the Device Control Register. Otherwise, this signal is in a 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 sink capability.

This signal gives an indication 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 up to 5 Volts.

DASP-

PDIAG-

This is a time-multiplexed signal which indicates that either a drive is active or that Device 1 is present. This signal is driven by Open-Drain driver and internally pulled up to 5 Volts through a 10 KΩ resistor.

During the Power-on initialization or after a RESET- is negated, DASP- is asserted by Device 1 within 400 ms to indicate that Device 1 is present. Device 0 allows up to 450 ms for Device 1 to assert the DASP- signal. If Device 1 is not present, Device 0 may assert DASP- to drive an LED indicator.

DASP- is negated following acceptance of the first valid command by Device 1. Anytime after negation of DASP- either drive (that is master or slave) may assert DASP- to indicate that a drive is active.

The PDIAG- signal is asserted by Device 1 to indicate to Device 0 that it has completed 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 negates 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 negates PDIAG- within 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 waits up to 6 seconds from the receipt

Deskstar 60 GXP Hard disk drive specification

of a valid Execute Drive Diagnostics command for drive 1 to assert PDIAG-. Device 1 clears BSY before asserting PDIAG- and 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 clear 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).

Device 1 releases PDIAG-/CBLID- no later than after the first command following a power on or hardware reset sequence so that the host may sample PDIAG-/CBLID- in order to detect the presence or absence of an 80-conductor cable assembly.

CSEL (Cable Select) (Optional)

The drive is configured as either Device 0 or 1 depending upon the value of CSEL.

If CSEL is grounded the device address is 0.

If CSEL is open the device address is 1.

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 by mistake.

IORDY

This signal is negated to extend the host transfer cycle when a drive is not ready to respond to a data transfer request, and may be negated when the host transfer cycle is less than 240 ns for PIO data transfer. 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.

DMACK-

This signal is 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 Volts through a 15 KΩ resistor and the tolerance of the resistor value is –50% to +100%.

DMARQ

This signal—used for DMA data transfers between host and drive—is asserted by the drive when it is ready to transfer data to or from the host. The direction of data transfer is controlled by DIOR- and DIOW-. This signal is used to handshake with the DMACKsignal. This signal is a 3-state line with 24 mA sink capability and internally pulled down to GND through a 10 KΩ resistor.

HDMARDY- (Ultra DMA)

This signal is used only for Ultra DMA data transfers between the host and the device. 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 the host and the device. 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 DD00–DD15 into the device. The host may stop toggling HSTROBE to pause an Ultra DMA data out transfer.

STOP (Ultra DMA)

This signal is used only for Ultra DMA data transfers between the host and the device. The STOP signal is asserted by the host prior to initiation of an Ultra DMA burst. The

STOP signal is negated by the host before data is transferred in an Ultra DMA burst. Assertion of STOP by the host during or after data transfer in an Ultra DMA mode signals the termination of the burst.

Deskstar 60 GXP Hard disk drive specification

DDMARDY- (Ultra DMA)

This signal is used only for Ultra DMA data transfers between the host and the drive. DDMARDY- is a flow control signal for Ultra DMA data out bursts. This signal is held

asserted by the device to indicate to the host that the device is ready to receive Ultra DMA data out transfers. The device may negate DDMARDY- to pause an Ultra DMA data out transfer.

DSTROBE (Ultra DMA)

This signal is used only for Ultra DMA data transfers between the host and the drive. DSTROBE is the data in strobe signal from the device for an Ultra DMA data in transfer.

Both the rising and falling edge of DSTROBE latch the data from DD00–DD15 into the host. The device may stop toggling DSTROBE to pause an Ultra DMA data in transfer.

Note: The termination resistors at the device side are implemented as follows:

9.1.8 Addressing of registers

The host addresses the drive through a set of registers called the Task File. These registers are mapped into the I/O space. Two chip select lines (CS0- and CS1-) and three address lines (DA0-02) are used to select one of these registers, while a DIOR- or DIOW- is provided at the specified time.

The CS0- is used to address Command Block registers while the CS1- is used to address the Control Block registers. The following table shows the I/O address map.

DIOW- = 0 (Write)DIOR- = 0 (Read)DA0DA1DA2CS1-CS0-

Note: "Addr." field is shown just as an example.

During DMA operation (from writing to the command register until an interrupt) all registers are not accessible. For example, the host is not supposed to read the status register contents before interrupt —the value is invalid.

Figure 35. I/O address map

9.1.9 Cabling

The maximum cable length from the host system to the drive plus circuit pattern length in the host system must not exceed 18 inches.

For data transfers greater than 8.3 MB/s it is recommended that designs measures are used to reduce cable noise and cross-talk. Examples of design modification include use of shorter cable, bus termination, and the use of shielded cable.

The 80-conductor ATA cable assembly (P/N SFF-8049) must be used for systems operating at Ultra DMA modes 3, 4 and 5.

Notes:

1. To enable the CSEL mode (Cable Selection mode) the jumper block must be installed at position E-F. In the CSEL mode, the drive address is determined as follows:

•

When CSEL is grounded or at a low level, the drive address is 0 (Device0).

•

When CSEL is open or at a high level, the drive address is 1 (Device1).

2. Installing or removing the jumper blocks at position A-B or position C-D does not affect selection of either Device or Cable Selection mode.

3. The drive is set as Device 0—master—when shipped. The shipping default jumpers are located at positions A-B and G-H.

The hard disk drive shows no signs of corrosion inside or outside of hard drive assembly and is functional after being subjected to seven days of a 50°C temperature and 90% relative humidity.

9.3 DC power requirements

The following voltage specifications apply at the drive power connector. Damage to the drive electronics may result if the power supply cable is connected or disconnected while power is being applied to the drive (no hot plugging or unplugging is allowed). Connections to the drive should be made from a low voltage, isolated secondary circuit (SELV). There is no special power on/off sequencing required.

Figure 47. Power supply generated ripple at drive power connector

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

To prevent external electrical noise from interfering with the performance of the drive, the drive must be held in position by four screws in a user's system frame. There must be no electrical level difference at the four screw positions and less than ±300 millivolts peak-to-peak difference level must be maintained between the drive cover and the ground of the drive power connector.

9.3.4 Start up current

Since each drive model has the identical spindle motor design, rush currents shorter than 10 us in duration are ignored in the measurement of the start up current of each model. For this reason a single start up current graph represents each of the respective models in this specification.

9.4.1 Data integrity

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

9.4.2 Cable noise interference

To avoid any degradation of performance throughput or error rate when the interface cable is routed on top of or comes in contact with the hard disk assembly, the drive must be grounded electrically to the system frame by four drive mounting screws. The common mode noise or voltage level difference between the system frame and power cable ground or AT interface cable ground must be in the allowable level specified in the Section 9.3 "DC Power Requirements" on page 48.

9.4.3 Start/stop cycles

The drive withstands a minimum of 40,000 start/stop cycle under a 40°C environment and a minimum of 10,000 start/stop cycle under any other extreme temperature or humidity environment within the operating range (refer to Section 9.2.1 on page 47).

9.5.4 Drive mounting

The drive will operate in all axes (6 directions). Performance and error rate will stay within specification limits if the drive is operated in the other orientations from which it was formatted.

For reliable operation it is recommended that the drive be mounted by using appropriate length side or bottom mounting screws with 6-32 UNC thread count or equivalent mounting hardware. Proper mounting is essential to prevent the drive from excessive motion or vibration during seek operation or spindle rotation.

Consult with your IBM Corporation distribution representative if your mounting application may possibly be considered out of compliance with this specification.

When performing any drive level vibration and shock test, mount the drive to the table using the bottom four screws.

Do not cover the breather hole—illustrated in Figure 50 on page 51—to keep air pressure inside of the disk enclosure equal to the atmospheric pressure outside of the drive enclosure.

9.5.5 Head unload and actuator lock

During an unload the heads are moved out from the disks to protect the disk data during shipping, moving, and storage. Upon power down the heads are automatically unloaded from the disk area. The head actuator locking mechanism secures the heads in the unload position.

Figure 64. 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. The use of bit 4 is command dependent. After the DMA Queued commands it is used as SERV. After any

other commands are reset, it is used as DSC.

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

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

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

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

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

Service. SRV is set to one when the device is ready to transfer data after it releases the bus for execution of a DMA Queued command.

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

Corrected Data. Always zero.

IDX

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

Deskstar 60 GXP Hard disk drive specification

ERR

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

13.0 General operation

13.1 Reset response

There are three types of resets in ATA:

Power On Reset (POR)

The device executes a series of electrical circuitry diagnostics, spins up the HDA, tests speed and other mechanical parametrics, and sets default values.

Hard Reset (Hardware Reset)

RESET- signal is negated in ATA Bus. The device resets the interface circuitry as well as Soft Reset.

Soft Reset (Software Reset)

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

The actions of each reset is shown in the following figure.

Deskstar 60 GXP Hard disk drive specification

13.3 Diagnostic and Reset considerations

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

Power On Reset

DASP- is read by Device 0 to determine if Device 1 is present. If Device 1 is present, Device 0 must 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 assert DASP- to indicate device activity.

Hard Reset, Soft Reset

If Device 1 is present Device 0 must 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 must 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.

Execute Device Diagnostic

If Device 1 is present, Device 0 must 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 must 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 the device is active.

In all the above cases Power on, RESET-, Soft reset, and the EXECUTE DEVICE DIAGNOSTIC command the Device 0 Error register as shown in the following figure.

'x' indicates the appropriate Diagnostic Code for the Power on, RESET–, Soft Reset, or Device Diagnostic error.

13.4 Sector Addressing Mode

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

All models of the drive support both Logical CHS Addressing Mode and LBA Addressing Mode as the sector addressing mode.

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

13.4.1 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 zero to the maximum value allowed by the current CHS translation mode but cannot exceed 15 (0Fh). Cylinders are numbered from zero 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 is also described in the Identify Device Information.

13.4.2 LBA Addressing Mode

Logical sectors on the device must be mapped linearly 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). Regardless 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 * heads per cylinder + heads) * sectors per track) + sector – 1

where On LBA addressing mode the LBA value is set to the following register:

heads per cylinder

Device/Head <--- LBA bits 27–24 Cylinder High <--- LBA bits 23–16 Cylinder Low <--- LBA bits 15– 8 Sector Number <--- LBA bits 7– 0

and

sectors per track

are the current translation mode values

Deskstar 60 GXP Hard disk drive specification

13.5 Overlapped and queued feature

Overlap allows devices to perform a bus release so that the other device on the bus may be used. To perform a bus release the device clears both DRQ and BSY to zero. When selecting the other device during overlapped operations, the host shall disable interrupts via the nIEN bit on the currently selected device before writing the Device/Head register to select the other device.

The only commands that may be overlapped are the following:

NOP (with 01h subcommand code) Read DMA Queued Service Write DMA Queued

For the READ DMA QUEUED and WRITE DMA QUEUED commands, the device may or may not perform a bus release. If the device is ready to complete the execution of the command, it may complete the command immediately. If the device is not ready to complete the execution of the command, the device may perform a bus release and complete the command via a service request.

Command queuing allows the host to issue concurrent commands to the same device. Only commands included in the overlapped feature set may be queued. If a queue exists when a non-queued command is received, the non-queued command must be aborted and the commands in the queue must be discarded. The ending status must be the ABORT command and the results are indeterminate.

The maximum queue depth supported by a device is indicated in word 73 of Identify Device information. A queued command shall have a Tag provided by the host in the Sector Count register to uniquely

identify the command. When the device restores register parameters during the execution of the SERVICE command, this Tag shall be restored so that the host may identify the command for which status is being presented. If a queued command is issued with a Tag value that is identical to the Tag value for a command already in the queue, the entire queue is aborted including the new command. The ending status is ABORT command and the results are indeterminate. If any error occurs, the command queue is aborted.

When the device is ready to continue processing a bus released command and BSY and DRQ are both cleared to zero, the device requests service by setting SERV to one, setting a pending interrupt, and asserting INTRQ if selected and if nIEN is cleared to zero. SERV shall remain set until all commands ready for service have been serviced. The pending interrupt must be cleared and the INTRQ negated by a Status register read or a write to the Command register.

When the device is ready to continue processing a bus released command and BSY or DRQ is set to one —that is the device is processing another command on the bus—and the device requests service by setting SERV to one. SERV shall remain set until all commands ready for service have been serviced. At command completion of the current command processing (i.e., when both BSY and DRQ are cleared to zero), the device shall process interrupt pending and INTRQ per the protocol for the command being completed. No additional interrupt shall occur due to other commands ready for service until after the SERV bit of the device has been cleared to zero.

When the device receives a new command while queued commands are ready for service, the device must execute the new command and process interrupt pending and INTRQ per the protocol for the new command. If the queued commands ready for service still exist at command completion of this command, SERV remains set to one but no additional interrupt shall occur due to commands ready for service.

When queuing commands, the host shall disable interrupts via the nIEN bit before writing a new command to the Command register and may re-enable interrupts after writing the command. When reading status at command completion of a command, the host shall check the SERV bit since the SERV bit may be set because the device is ready for service associated with another queued command. The host receives no additional interrupt to indicate that a queued command is ready for service.

13.6 Power management feature

The power management feature set permits a host to modify the behavior of a manner which reduces the power required to operate. The power management feature set provides a set of commands and a timer that enable a device to implement low power consumption modes.

The drive implements the following set of functions:

A Standby timer

Idle command

Idle Immediate command

Sleep command

Standby command

Standby Immediate command

13.6.1 Power modes

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

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

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

function or the write cache function.

13.6.2 Power management commands

The Check Power Mode command enables a host to determine if a device is currently in, going into, or leaving standby mode.

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

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

The Sleep command moves a device to sleep mode. The interface of the device 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 enters Standby mode.

13.6.3 Standby timer

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

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

Deskstar 60 GXP Hard disk drive specification

13.7 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.

13.7.1 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 the ability of that attribute 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.

13.7.2 Attribute values

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

13.7.3 Attribute thresholds

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

Deskstar 60 GXP Hard disk drive specification

13.7.4 Threshold Exceeded Condition

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

13.7.5 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.

13.7.6 Off-line read scanning

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

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

13.7.7 Error log

Logging of reported errors is supported. The device provides information on the last five errors which the device reported as described in the S.M.A.R.T. error log sector. The device may also provide additional vendor specific information on these reported errors. The error log is not disabled when S.M.A.R.T. is disabled. Disabling S.M.A.R.T. must disable the delivering of error log information via the S.M.A.R.T. READ LOG SECTOR command.

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

13.7.8 Self-test

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

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

13.8 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 hard disk drive even if the device is removed from the computer.

The following commands are supported for this feature.

Deskstar 60 GXP Hard disk drive specification

13.8.1 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.

13.8.2 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, only the Master Password with a Security Erase Unit command can unlock the device. User data is then erased.

13.8.3 Passwords

This function can have two kinds of passwords as described as follows:

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.

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

Identify Device Information word 92 contains the value of the Master Password Revision Code set when the Master Password was last changed. Valid values are 0001h through FFFEh.

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 the device is then locked on next power on reset or hard reset.

13.8.4 Operation example

13.8.4.1 Master Password setting

The system manufacturer or dealer can set a new Master Password from default Master Password using the Security Set Password command without enabling the Device Lock Function.

The Master Password Revision Code is set to FFFEh as shipping default by the drive manufacturer.

Deskstar 60 GXP Hard disk drive specification

13.8.4.2 User Password setting

When a User Password is set, the device will automatically enter lock mode the next time the device is powered on.

13.8.4.5 Attempt limit for SECURITY UNLOCK command

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

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