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:

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

mated velocity.

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

3.2 Head disk assembly

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

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

3.3 Actuator

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

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

the disk where it is parked.

4.4 Performance characteristics

Drive performance is characterized by the following parameters:

Ÿ Command overhead Ÿ Mechanical positioning

- Seek time

- Latency

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

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

Ÿ Instantaneous disk-buffer transfer rate (Mbyte/sec) is derived by the formula

(Number of sectors on a track) * 512 * (revolution/sec)

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

Ÿ 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 the formula (Sustained Transfer Rate) = A / (B +C +D ) where

A = (Number of data sectors per cylinder) B = ((# of Surface per cylinder) - 1) C = (Cylinder change time) D = (# of Surface)

Ÿ Instantaneous buffer-host transfer rate (Mbyte/sec) defines the maximum data transfer rate on the

AT Bus. It also depends on the speed of the host.

The method of measurement is given in 4.4.6, “Throughput” on page 0.

4.4.5 Buffering Operation (Look ahead/Write cache)

To improve the total performance, the drive utilizes a ring buffer for look ahead and write cache. The total 380 KB (DTLA-305XXX) and 1916 KB (DTLA-307XXX) of the buffer is divided into multiple segmented blocks for write buffer or read buffer use.

Write data will be cached in the buffer for the random block request.

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

Ÿ Data areas are optimally used. Ÿ No extra sector is wasted as a spare throughout user data areas. Ÿ 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

Ÿ The drive retains recorded information under all non-write operations. Ÿ No more than one sector can be lost by power down during write operation while write cache is dis-

abled.

Ÿ 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.

Ÿ Hard reset does not cause any data loss. Ÿ 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

Ÿ 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.

Ÿ 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:

Ÿ Access recalibration/tuning is complete Ÿ Spindle speed meets requirements for reliable operation Ÿ 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:

Ÿ Spindle speed outside requirements for reliable operation Ÿ Occurrence of a WRITE FAULT condition

. Signal special definitions for Ultra DMA

The pin assignments of interface signals are listed in the figure below:

Figure 18. Table of signals

I/OSIGNALPIN

Notes:

1. "O" designates an output from the drive.

2. "I" designates an input to the drive.

3. "I/O" designates an input/output common.

4. "OC" designates open-collector or open-drain output.

5. 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.

DD0-DD15 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.

DA0-DA2 Address used to select the individual register in the drive. CS0- 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. (See Figure 42 on page 0.)

CS1- 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 42 on page 0.)

RESET- This line is used to reset the drive. It shall be kept in Low logic state during power up and

in High thereafter.

DIOW- The strobe signal asserted by the host to write device registers or the data port. DIOR- The strobe signal asserted by the host to read device registers or the data port. INTRQ Interrupt is enabled only when the drive is selected and the host activates the nIEN bit in

the Device Control Reg. 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. IRQ is reset to zero by a host read of the status register or a write to the Command Reg. This signal is a 3-State line with 24 mA sink capability.

IOCS16- 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 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 Open-Drain driver and internally pulled-up to 5 volts through a 10k

Ω resistor.

During 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 DASPto drive an LED indicator.

DASP- 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.

PDIAG- PDIAG- shall be asserted by device 1 to indicate to device 0 that it has completed diag-

nostics. This line is pulled-up to 5 volts in the drive through a 10k

Ω resistor.

Following a Power On Reset, software reset, or RESET-, drive 1 shall negate PDIAGwithin 1 ms (to indicate to device 0 that it is busy). Drive 1 shall then assert PDIAGwithin 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 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 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.

Deskstar 40GV & 75GXP hard disk drive specifications

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 shall release 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.

Ÿ If CSEL is grounded, the device address is 0. Ÿ 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 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 K

Ω resistor and the tolerance of

the resistor value is –50% to +100%.

DMARQ This signal, used for DMA data transfers between host and drive, 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 DIOR- and DIOW-. This signal is used on a handshake manner with DMACK-. This signal is a 3-state line with 24mA sink capability and internally pulled down to GND through 10 K

Ω 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 DD(15:0) 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. STOP shall be asserted by the host prior to initiation of an Ultra DMA burst. STOP shall

be 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.

DDMARDY- (Ultra DMA)

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

The host addresses the drive through a set of registers called the Task File. These registers are mapped into the I/ O space of the host. 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 Control Block registers. The following table shows the I/ O address map.

DA0DA1DA2

Figure 42. I/O address map

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 status register contents before interrupt (the value is invalid).

7.2.6 Cabling

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

For higher data transfer application (>8.3MB/sec) a modification in the system design is recommended to reduce cable noise and/or cross-talk, such as a shorter cable, bus termination, or a shielded cable.

For systems operating with Ultra DMA mode 3 or 4, 80-conductor ATA cable assembly (SFF-8049) shall be used.

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

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

7.6 Reliability

7.6.1 Cable noise interference

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

7.6.2 Start/stop cycles

The drive withstands a minimum of 40,000 start/stop cycles in a 40° C environment and a minimum of 10,000 start/stop cycles in extreme temperature or humidity or complete stop disk rotation. See Figure 48 on page 0 and Figure 49 on page 0.

7.7.5 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, the drive must be mounted in the system securely enough to prevent excessive motion or vibration of the drive during seek operation or spindle rotation, using appropriate screws or equivalent mounting hardware.

The recommended mounting screw torque is 0.6 - 1.0 Nm (6-10 Kgf.cm). The recommended mounting screw depth is 4 mm maximum for bottom and 4.5 mm maximum for hori-

zontal mounting. If an electrical screw driver is used for moutning screws, a current control model should be used. Drive level vibration test and shock test are to be conducted with the drive mounted to the table using the

bottom four screws.

Figure 72. 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.

Bit Definitions

BSY 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.

ERRIDXCORRDRQ

DRDY (RDY) 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.

DF 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.

DSC Device Seek Complete. DSC=1 indicates that a seek has completed and the device head

is settled over a track. DSC is set to 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.

SERV (SRV) 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.

DRQ Data Request. DRQ=1 indicates that the device is ready to transfer a word or byte of

data between the host and the device. The host should not write the Command register when DRQ=1.

CORR (COR)Corrected Data. Always zero. IDX Index. IDX=1 once per revolution. Since IDX=1 only for a very short time during each re-

volution, 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.

ERR Error. ERR=1 indicates that an error occurred during execution of the previous com-

mand. The Error Register should be read to determine the error type. The device sets

10.1 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.

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 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 assert DASP- to indicate device activity.

Hard Reset, Soft Reset

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.

Execute Device Diagnostic

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 the device is active.

10.3 Sector Addressing Mode

All addressing of data sectors recorded on the drive media is 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. So a host system must set the L bit to 1 if the host uses LBA Addressing mode.

10.3.1 Logical CHS Addressing Mode

The logical CHS addressing is made up of three fields: cylinder number, head number and 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 is also described in the Identify Device Information.

10.3.2 LBA Addressing Mode

Logical sectors on the device shall 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 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:

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

receives no additional interrupt to indicate that a queued command is ready for service.

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

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 nonqueued command shall be aborted and the commands in the queue shall be discarded. The ending status shall be 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 iden-

tify 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 shall be cleared and 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 (i.e., the device is processing another command on the bus), 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 shall 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

10.5 Power management feature

The power management feature functions permit a host to reduce the power required to operate the drive. It 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:

Ÿ Standby timer Ÿ Idle command Ÿ Idle Immediate command Ÿ Sleep command Ÿ Standby command Ÿ Standby Immediate command

10.5.1 Power modes

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

In Standby Mode the device interface is capable of accepting commands, but as the media may not 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.

10.5.2 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 directly 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.

10.5.3 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.

10.6 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.

10.6.1 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.

10.6.2 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.

10.6.3 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 40GV & 75GXP hard disk drive specifications

10.6.4 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.

10.6.5 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.

10.6.6 Off-line read scanning

The device provides the off-line read scanning feature with reallocation. This is the extension of the offline 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

10.6.7 Error log

Logging of reported errors is supported. The device provides information on the last five errors that the device reported as described in the SMART error log sector. The device may also provide additional vendor specific information on these reported errors. The error log is not disabled when SMART is disabled. Disabling SMART shall disable the delivering of error log information via the SMART READ LOG SECTOR command.

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

10.6.8 Self-test

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

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

10.7.4.5 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.
