4.4 Performance characteristics
Drive performance is characterized by the following parameters:
• Command overhead
• Mechanical head positioning
- Seek time
- Latency
• Data transfer speed
• Buffering operation (read ahead/write cache)
Note: All the above parameters contribute to drive performance. There are other parameters that contribute to the performance of the actual system. This specification tries to define the bare drive characteristics, not system throughput, which depends on the system and the application.

“Typical” and “Max” are used throughout this document and are defined as follows:
Typical Average of the drive population tested at nominal environmental and voltage conditions.
Max Maximum value measured on any one drive over the full range of the environmental and voltage
The seek time is measured from the start of the actuator’s motion to the start of a reliable read or write operation. A reliable read or write implies that error correction or recovery is not used to correct arrival problems. The average seek time is measured as the weighted average of all possible seek combinations.

The device is capable of responding immediately to idle media access requests. All electronic components remain powered and the full frequency servo remains operational.
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.
The head is unloaded onto the ramp position. The spindle motor is rotating at full speed.

5.0 Data integrity
5.1 Data loss at 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 whenever 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 operations
• 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 lies outside the requirements for reliable operation
• The occurrence of a Write Fault condition
Travelstar 80GN Hard Disk Drive Specification
21
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 procedures are reported to the host system as non-recoverable 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 80GN Hard Disk Drive Specification

5.8 ECC
The 52 byte four way 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 48 bytes are Read Solomon ECC. Each interleave has 12 bytes for ECC. Hardware logic corrects up to 20 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.

To avoid any degradation of performance throughput or error when the interface cable is routed on top or comes in
Travelstar 80GN Hard Disk Drive Specification
28
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.
6.3.4 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-6.
• The power-off sequence of the drive should comply with the required power off sequence described in Sec-
tion 6.3.6.2, “Required Power-Off Sequence” on page 30.
Service life of the drive is approximately 5 years or 20,000 power on hours, which 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.
6.3.5 Preventive maintenance
None
6.3.6 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.
6.3.6.1 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
Travelstar 80GN Hard Disk Drive Specification
29
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.
6.3.6.2 Required Power-Off Sequence
The required BIOS sequence for removing power from the drive is as follows:
Step 1: Issue one of the following command:
• 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
Step 3: Terminate power to the drive
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.
6.3.6.3 Power Switch design considerations
In systems that use this drive consideration should be given to the design of the system power switch.
Hitachi recommends that the switch operate under control of the BIOS rather than be hardwired. The same recommendation is made for cover-close switches. When a hardwired switch is turned off, emergency unload occurs, as
6.3.6.4 Test considerations
Start/stop testing is classically performed to verify head/disk durability. The heads do not land on the disk, therefore 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 by power cycling the drive. 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 Hitachi recommends

6.4.4 Mounting orientation
The drive will operate in all axes (six directions) and will stay within the specified error rates when tilted ±5degrees from these positions.
Performance and error rate will stay within specification limits if the drive is operated in the other permissible orientations from which it was formatted. Thus a drive formatted in a horizontal orientation will be able to run vertically and vice versa.
The recommended mounting screw torque is 3.0±0.5 kgf-cm.
The recommended mounting screw depth is 3.0±0.3 mm for bottom and 3.5±0.5 mm for horizontal mounting.
The user is responsible for using the appropriate screws or equivalent mounting hardware to mount the drive securely enough to prevent excessive motion or vibration of the drive at seek operation or spindle rotation.

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.

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 16mA 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 16mA of sink capability.
Travelstar 80GN Hard Disk Drive Specification
41
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 5.0 volts through a 10 k. 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 on a host. 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.
Caution
The host doesshall not drive DASP-. If the host connects to DASP- for any purpose, the host shall ensure that the signal level detected on the interface for DASP- shall maintain VoH and VoL compatibility, given the IoH and IoL requirements of the DASP- device drivers.
Caution
When DASP- is negated, the line is in a high impedance state. The signal level may look less than 5.0V even though the line is pulled up to 5.0V through a resistor."
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 3.3 volts in the drive through a 10 kW 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 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. 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
Travelstar 80GN Hard Disk Drive Specification
42
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 16mA 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 15kW 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 16mA sink capability and internally pulled down to GND through a 10 kW resistor.
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.
STOP (Ultra DMA)
This signal is used only for Ultra DMA data transfers between host and drive.
The STOP signal shall be asserted by the host prior to initiation of an Ultra DMA burst. A 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 host and drive.
The signal 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 host and drive.
The signal DSTROBE is the data in strobe signal from the device for an Ultra DMA data in transfer. Both the rising and the falling edge of DSTROBE latch the data from DD (15:0) into the host. The device may stop toggling DSTROBE to pause an Ultra DMA data in transfer.

7.10 Drive address setting
A jumper placed on the interface connector determines the drive address. Three drive addresses are shown below.
Two addresses require the setting of a jumper.

1 2 3 4
4 2

Figure 3: Drive address setting
Setting 1—Device 0 (Master) (no jumper is used)
Setting 2—Device 1 (Slave)
Setting 3—Cable Select
Setting 4—Do not attach a jumper here
Setting 5—Do not attach a jumper here
The default setting at shipment is Setting 1 (no jumper).
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.

7.11 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 80GN.
The interface conforms to the Working Document of Information technology, AT Attachment with Packet Interface
“Deviations from standard” on page 61.
The drive supports the following functions as Vendor Specific Functions:
• Address Offset Feature
• Format Unit Function
• SENSE CONDITION command
8.2 Terminology
Device
Host
First Command
INTRQ
The Travelstar 80GN drive
Host indicates the system that the device is attached to.
The first command which is executed after the power on reset (also known as a hard reset) is the Standby mode command.
Interrupt request (Device or Host)

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-6) Revision 3, dated 30 October 2001, 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 negative reliability status.

11.0 General
11.1 Reset response
ATA has the following three types of resets:
Power On Reset (POR) 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.
Hard Reset (Hardware Reset) The RESET signal is negated in the ATA Bus. The device resets the interface circuitry and sets the default values.
Soft Reset (Software Reset) 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 requirement.
The actions of each reset are shown in the table below.

11.3 Diagnostic and Reset considerations

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

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

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.

Standby Immediate
Sleep

Load/Unload condition is not changed by Soft Reset
Load is also invoked as the idle command.
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.
11.4.3 Required power-off sequence
The following are examples of such problems which can result when power is removed on most drives at an arbitrary time:
• 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.
Travelstar 80GN Hard Disk Drive Specification
72
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
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.
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.
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:
Device
LBA High
LBA Mid
LBA Low
<- - - LBA bits 27–24
<- - - LBA bits 23–16
<- - - LBA bits 15–8
<- - - LBA bits 7–0
Travelstar 80GN Hard Disk Drive Specification

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:
• A Standby timer
• Idle command
• Idle Immediate command
• Sleep command
• Standby command
• Standby Immediate command
11.6.1 Power mode
Sleep 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.
Standby
Mode
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.
Idle Mode
Refer to Section 11.7 “Advanced Power Management (ABLE-3) feature” on page 75.
Active
Mode
The device is in execution of a command or accessing the disk media with the read lookahead 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 time
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 80GN Hard Disk Drive Specification
74
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:
Table 49: Power conditions
Mode
Active
Idle
Standby
Sleep
BSY o x x o
RDY Interface active
1 x x
1
Yes
Yes

No
Media

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 19 for the initial power mode selection.
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
Travelstar 80GN Hard Disk Drive Specification
75
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 91, bit 7-0 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 300ms.
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 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 80GN Hard Disk Drive Specification
77
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,
Sleep command, and Hard Reset, but also by the Standby timer. So 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 30 minutes have passed since the last saving, besides above condition.
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:
Security Set Password

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.
Device Frozen Mode 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 When the device lock function is enabled and the User Password is forgotten, the device can be unlocked via a Master Password.
Maximum level security
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.
Travelstar 80GN Hard Disk Drive Specification
78
11.9.3 Password
This function can have two types of passwords as described below.
Master Password
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.
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 Hitachi Global Storage Technologies can unlock a device that is locked with a user password
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.
11.9.4.1 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.
11.9.4.2 User Password setting
When a User Password is set, the device will automatically enter lock mode the next time the device is powered on.

11.9.4.5 Attempt limit for the SECURITY UNLOCK command
The SECURITY UNLOCK command has an attempt limit the purpose of which is to prevent someone from attempting to unlock the drive with various passwords numerous 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 then the SECURITY ERASE UNIT command and the SECURITY
UNLOCK command are 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.

11.10 Protected Area Function
Protected Area Function provides a protected area which cannot be accessed via conventional methods. This protected area is used to contain critical system data such as BIOS or system management information. The contents of the entire system main memory may also be dumped into the protected area to resume after a system power off.
The LBA/CYL changed by the following commands affects the Identify Device Information.
Two commands are defined for this function:
• Read Native Max ADDRESS ('F8'h)
• Set Max ADDRESS ('F9'h)
Four security extension commands are implemented as sub functions of the Set Max ADDRESS:
• Set Max SET PASSWORD
• Set Max LOCK
• Set Max FREEZE LOCK
• Set Max UNLOCK
11.10.1 Example for operation (In LBA Mode)
The following example uses hypothetical values.
Device characteristics:
Capacity (native)
Max LBA (native)
Required size for protected area
Required blocks for protected area
Customer usable device size
Customer usable sector count
LBA range for protected area
536,870,912 bytes (536MB)
1,048,575 (0FFFFFh)
8,388,608 bytes
16,384 (004000h)
528,482,304 bytes (528MB)
1,032,192 (0FC000h)
0FC000h to 0FFFFFh
1. Shipping drives from the drive manufacturer
When the drive is shipped from the manufacturer, the device has been tested to have a capacity of 536MB, flagging the media defects not visible by the system.
2. Preparing drives at system manufacturer
Special utility software is required to define the size of the protected area and to store the data in it. The sequence is:
Travelstar 80GN Hard Disk Drive Specification
83
Issue Read Native Max ADDRESS command to get the real device max of LBA/CYL. Returned value shows that native device Max LBA is 0FFFFFh regardless of the current setting.
Make the entire device accessible, including the protected area, by setting the device Max LBA as 0FFFFFh via Set Max ADDRESS command. The option could be either nonvolatile or volatile.
Test the sectors for protected area (LBA > = 0FC000h) if required.
Write information data such as BIOS code within the protected area.
Change maximum LBA using Set Max ADDRESS command to 0FBFFFh with nonvolatile option.
From this point, the protected area cannot be accessed until next Set Max ADDRESS command is issued. Any
BIOS, device driver, or application software accesses the drive as if it is a 528 MB device because the device behaves like a 528 MB device.
3. Conventional usage without system software support:
Since the drive works as a 528 MB device, there is no special care required for normal use of this device.
4. Advanced usage using protected area.
The data in the protected area is accessed by the following steps.
1. Issue Read Native Max ADDRESS command to get the real device max LBA/CYL. Returned value shows that native device Max LBA is 0FFFFFh regardless of the current setting.
2. Make entire device accessible, including the protected area, by setting device Max LBA as 0FFFFFh via Set
Max ADDRESS command with the volatile option. By using this option, unexpected power removal or reset will prevent the protected area from remaining accessible.
3. Read information data from protected area.
4. Issue hard reset or POR to inhibit any access to the protected area.
11.10.2 Set Max security extension commands
The Set Max SET PASSWORD command allows the host to define the password to be used during the current power on cycle. This password is not related to the password used for the Security Mode Feature set. When the password is set, the device is in the Set Max Unlocked mode.
This command requests a transfer of a single sector of data from the host. The following figure defines the content of this sector of information. The password is retained by the device until the next power cycle. When the device accepts this command, the device is in Set Max Unlocked mode.
Table 54: Set Max SET PASSWORD data content
Word
0
1-16
17-255

Password (32 bytes)
Reserved
The Set Max LOCK command allows the host to disable the Set Max commands (except Set Max UNLOCK and
Set Max FREEZE LOCK) until the next power cycle or the issuance and acceptance of the Set Max UNLOCK command. When this command is accepted, the device is in the Set Max Locked mode.
The Set Max UNLOCK command changes the device from the Set Max Locked mode to the Set Max Unlocked mode.
Travelstar 80GN Hard Disk Drive Specification
84
This command requests a transfer of a single sector of data from the host. The figure shown above defines the content of this sector of information. The password supplied in the sector of data transferred is compared with the stored Set Max password. If the password compare fails, then the device returns command aborted and decrements the unlock counter. On the acceptance of the Set Max LOCK command, this counter is set to a value of five and is decremented for each password mismatch when Set Max UNLOCK is issued and the device is locked. When this counter reaches zero, then the Set Max UNLOCK command returns command aborted until a power cycle.
The Set Max FREEZE LOCK command allows the host to disable the SET MAX commands (including Set Max
UNLOCK) until the next power cycle. When this command is accepted the device is in the Set Max Frozen mode.
The password, the Set Max security mode, and the unlock counter do not persist over a power cycle but persist over a hardware or software reset.
NOTE: If this command is immediately preceded by a Read Native MAX ADDRESS command, it shall be interpreted as a Set Max ADDRESS command regardless of Feature register value.
Table 55: Set Max security mode transition
11.11 Address Offset Feature (vendor specific)
Computer systems perform initial code loading (booting) by reading from a predefined address on a disk drive. To allow an alternate bootable operating system to exist in a reserved area on a disk drive this feature provides a Set
Features function to temporarily offset the drive address space. The offset address space wraps around so that the entire disk drive address space remains addressable in offset mode. The Set Max pointer is set to the end of the reserved area to protect the data in the user area when operating in offset mode. This protection can be removed by a Set Max Address command to move the Set Max pointer to the end of the drive. But any commands which access sectors across the original native maximum LBA are rejected with error, even if this protection is removed by a Set
Max Address command.
11.11.1 Enable/Disable Address Offset Mode
Subcommand code 09h Enable Address Offset Mode offsets address Cylinder 0, Head 0, Sector 1, LBA 0, to the start of the nonvolatile protected area established using the Set Max Address command. The offset condition is
Travelstar 80GN Hard Disk Drive Specification
85
cleared by Subcommand 89h Disable Address Offset Mode, Hardware reset or Power on Reset. If Reverting to
Power on Defaults has been enabled by Set Features command, it is cleared by Soft reset as well. Upon entering offset mode the capacity of the drive returned in the Identify Device data is the size of the former protected area. A subsequent Set Max Address command with the address returned by the Read Max Address command allows access to the entire drive. Addresses wrap so the entire drive remains addressable.
If a nonvolatile protected area has not been established before the device receives a Set Features Enable Address
Offset Mode command, the command fails with Abort error status.
Disable Address Offset Feature removes the address offset and sets the size of the drive reported by the Identify
Device command back to the size specified in the last nonvolatile Set Max Address command.
Table 56: Device address map before and after Set Feature
11.11.2 Identify Device Data
Identify Device data, word 83, bit 7 indicates the device supports the Address Offset Feature. Identify Device data, word 86, bit 7 indicates the device is in Address Offset mode.
11.11.3 Exceptions in Address Offset Mode
Any commands which access sectors across the original native maximum LBA are rejected with error, even if the access protection is removed by a Set Max Address command.
Read Look Ahead operation is not carried out, even if it is enabled by the Set Feature command.
Travelstar 80GN Hard Disk Drive Specification
86
11.12 Seek Overlap
The drive provides accurate seek time measurement method. The seek command is usually used to measure the device seek time by accumulating execution time for a number of seek commands. With typical implementation of the seek command, this measurement must include the device and host command overhead. To eliminate this overhead, the drive overlaps the seek command as described below.
The first seek command completes before the actual seek operation is over. Then the device can receive the next seek command from the host. However, the actual seek operation for the next seek command starts right after completion of the actual seek operation for the first seek command. The execution of two seek commands overlaps excluding the actual seek operation.
With this overlap, total elapsed time for a number of seek commands is the total accumulated time for the actual seek operation plus one pre and post overhead. When the number of seeks is large, this overhead can be ignored.
Table 57: Seek overlap

11.13 Write Cache function
Write cache is a performance enhancement whereby the device reports completion of the write command (Write
Sectors and Write Multiple) to the host as soon as the device has received all of the data in its buffer. The device assumes responsibility to write the data subsequently onto the disk.
• While writing data after completed acknowledgment of a write command, soft reset, or hard reset does not affect its operation. But power off terminates writing operation immediately and unwritten data is lost.
• Flush cache, Soft reset, Standby, Standby Immediate, and Sleep are executed after the completion of writing to disk media on enabling write cache function. The host system can confirm the completion of write cache operation by issuing flush cache command, Soft reset, Standby command, Standby Immediate command, or Sleep command, and confirming the completion of the issued command.
Travelstar 80GN Hard Disk Drive Specification
87
11.14 Reassign Function
The Reassign Function is used with read commands and write commands. The sectors of data for reassignment are prepared as the spare data sector. The one entry can register 256 consecutive sectors maximum.
This reassignment information is registered internally, and the information is available right after completing the reassign function. Also the information is used on the next power on reset or hard reset.
If the number of the spare sector reaches 0 sector, the reassign function will be disabled automatically.
The spare tracks for reassignment are located at regular intervals from Cylinder 0. As a result of reassignment, the physical location of logically sequenced sectors is dispersed.
11.14.1 Auto Reassign Function
The sectors that show some errors may be reallocated automatically when specific conditions are met. The spare tracks for reallocation are located at regular intervals from Cylinder 0. The conditions for auto-reallocation are described below.
Nonrecovered write errors
When a write operation can not be completed after the Error Recovery Procedure (ERP) is fully carried out, the sector(s) 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 fails.
If the number of available spare sectors reaches 16 sectors, the write cache function will be disabled automatically.
Nonrecovered read errors
When a read operation fails after a defined 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 verifications is performed automatically. When the result of this verification meets the criteria, this sector is reallocated.
Recovered read errors
When a read operation for a sector fails once and then is recovered at the specific ERP step, this sector of data is reallocated automatically. A media verification sequence may be run prior to the relocation according to the predefined conditions.
Travelstar 80GN Hard Disk Drive Specification

11.15 48-bit Address Feature Set
The 48-bit Address feature set allows devices with capacities up to 281,474,976,710,655 sectors. This allows device capacity up to 144,115,188,075,855,360 bytes. In addition, the number of sectors that may be transferred by a single command are increased by increasing the allowable sector count to 16 bits.
• Commands unique to the 48-bit Address feature set are:
• Flush Cache Ext
• Read DMA Ext
• Read Multiple Ext
• Read Native Max Address Ext
• Read Sector(s) Ext
• Read Verify Sector(s) Ext
• Set Max Address Ext
• Write DMA Ext
• Write Multiple Ext
• Write Sector(s) Ext
The 48-bit Address feature set operates in LBA addressing only. Devices also implement commands using 28-bit addressing, and 28-bit and 48-bit commands may be intermixed.
In a device, the Features, the Sector Count, the LBA Low/Mid/High registers are a two-byte-deep FIFO. Each time one of these registers is written, the new content written is placed into the "most recently written" location and the previous content is moved to "previous content" location.
The host may read the "previous content" of the Features, the Sector Count, the LBA Low/Mid/High registers by first setting the High Order Bit (HOB, bit 7) of the Device control register to one and then reading the desired register. If HOB in the Device Control register is cleared to zero, the host reads the "most recently written" content when the register is read. A write to any Command Block register shall cause the device to clear the HOB bit to zero in the Device Control register. The "most recently written" content always gets written by a register write regardless of the state of HOB in the Device Control register.
Support of the 48-bit Address feature set is indicated in the Identify Device response bit 10 word 83. In addition, the maximum user LBA address accessible by 48-bit addressable commands is contained in Identify Device response words 100 through 103.
When the 48-bit Address feature set is implemented, the native maximum address is the value returned by a Read
Native Max Address Ext command. If the native maximum address is equal to or less than 268,435,455, a Read
Native Max Address shall return the native maximum address. If the native maximum address is greater than
268,435,455, a Read Native Max Address shall return a value of 268,435,455.

12.0 Command protocol
The commands are grouped into different classes according to the protocols followed for command execution. The command classes with their associated protocols are defined below.
For all commands, the host must first check to see if BSY = 1, and should proceed no further unless and until
BSY = 0. For all commands, the host must also wait for RDY = 1 before proceeding.
A device must maintain either BSY = 1 or DRQ = 1 at all times until the command is completed. The INTRQ signal is used by the device to signal most, but not all, times when the BSY bit is changed from 1 to 0 during command execution.
A command shall only be interrupted with a hardware or software reset. The result of writing to the Command register while BSY = 1 or DRQ = 1 is unpredictable and may result in data corruption. A command should only be interrupted by a reset at times when the host thinks there may be a problem, such as a device that is no longer responding.
Interrupts are cleared when the host reads the Status Register, issues a reset, or writes to the Command Register.
See Section 14.0, “Time-out values” on page 193 for the device time-out values.
12.1 Data In commands
The following are Data In commands:
• Identify Device
• Read Buffer
• Read Long
• Read Multiple
• Read Multiple EXT
• Read Sector(s)
• Read Sector(s) EXT
• S.M.A.R.T. Read Attribute Values
• S.M.A.R.T. Read Attribute Thresholds
• S.M.A.R.T. Read log sector
Execution includes the transfer of one or more 512 byte (> 512 bytes on Read Long) sectors of data from the device to the host.
1. The host writes any required parameters to the Features, Sector Count, LBA, Cylinder, and Device Registers.
2. The host writes the command code to the Command Register.
3. For each sector (or block) of data to be transferred: a. The device sets BSY = 1 and prepares for data transfer.
b. When a sector (or block) of data is available for transfer to the host, the device sets BSY = 0, sets
DRQ = 1, and interrupts the host.
c. In response to the interrupt, the host reads the Status Register.
d. The device clears the interrupt in response to the Status Register being read.
e. The host reads one sector (or block) of data via the Data Register.
f. The device sets DRQ = 0 after the sector (or block) has been transferred to the host.
Travelstar 80GN Hard Disk Drive Specification page 91
4. For the Read Long command: a. The device sets BSY = 1 and prepares for data transfer.
b. When the sector of data is available for transfer to the host, the device sets BSY = 0 and DRQ=1 and interrupts the host.
c. In response to the interrupt, the host reads the Status Register.
d. The device clears the interrupt in response to the Status Register being read.
e. The host reads the sector of data including ECC bytes via the Data Register.
f. The device sets DRQ = 0 after the sector has been transferred to the host.
The Read Multiple command transfers one block of data for each interrupt. The other commands transfer one sector of data for each interrupt.
Note that the status data for a sector of data is available in the Status Register before the sector is transferred to the host.
If the device detects an invalid parameter, then it will abort the command by setting BSY = 0, ERR = 1, ABT = 1, and interrupting the host.
If an error occurs, the device will set BSY = 0, ERR = 1, and DRQ = 1. The device will then store the error status in the Error Register and interrupt the host. The registers will contain the location of the sector in error. The error location will be reported using CHS mode or LBA mode. The mode is decided by the mode select bit (bit 6) of the
Device/Head register upon issuing the command.
If an Uncorrectable Data Error (UNC = 1) occurs, the defective data will be transferred from the media to the sector buffer and will be available for transfer to the host at the host's option. In case of a Read Multiple command, the host should complete transfer of the block which includes the error from the sector buffer and terminate whatever type of error that occurred.
All data transfers to the host through the Data Register are 16 bits. The ECC bytes are an exception having only
8 bits.
12.2 Data Out Commands
The following are Data Out commands:
• Device Configuration SET
• Format Track
• Security Disable Password
• Security Erase Unit
• Security Set Password
• Security Unlock
• Set Max SET PASSWORD
• Set Max UNLOCK
• S.M.A.R.T. Write log sector
• Write Buffer
• Write Long

Execution includes the transfer of one or more 512 byte (> 512 bytes on Write Long) sectors of data from the host to the device.
1. The host writes any required parameters to the Features, Sector Count, LBA, and Device Registers.
2. The host writes the command code to the Command Register.
3. The device sets BSY = 1.
4. For each sector (or block) of data to be transferred: a. The devics BSY = 0 and DRQ = 1 when it is ready to receive a sector (or block).
b. The host writes one sector (or block) of data via the Data Register.
c. The device sets BSY = 1 after it has received the sector (or block).
d. When the device has finished processing the sector (or block), it sets BSY = 0 and interrupts the host.
e. In response to the interrupt, the host reads the Status Register.
5. For the Write Long Command: a. The device sets BSY = 0 and DRQ = 1 when it is ready to receive a sector.
b. The host writes one sector of data including ECC bytes via the Data Register.
c. The device sets BSY = 1 after it has received the sector.
d. After processing the sector of data the device sets BSY = 0 and interrupts the host.
e. In response to the interrupt, the host reads the Status Register.
f. The device clears the interrupt in response to the Status Register being read.
The Write Multiple command transfers one block of data for each interrupt. The other commands transfer one sector of data for each interrupt.
If the device detects an invalid parameter, then it will abort the command by setting BSY = 0, ERR = 1, ABT = 1, and interrupting the host.
If an uncorrectable error occurs, the device will set BSY = 0 and ERR = 1, store the error status in the Error Register, and interrupt the host. The registers will contain the location of the sector in error. The error location will be reported with CHS mode or LBA mode. The mode is decided by the mode select bit (bit 6) of the Device/Head register on issuing the command.
All data transfers to the host through the Data Register are 16 bits. The ECC bytes are an exception having only
8 bits.

Execution of these commands involves no data transfer: a. The host writes any required parameters to the Features, Sector Count,LBA High, LBA Mid, LBA Low, and Device Registers.
b. The host writes the command code to the Command Register.
c. The device sets BSY = 1.
d. When the device has finished processing the command, it sets BSY = 0 and interrupts the host.
e. In response to the interrupt, the host reads the Status Register.
f. The device clears the interrupt in response to the Status Register being read.

12.4 DMA Data Transfer commands:
• Read DMA
• Read DMA EXT
• Write DMA
• Write DMA EXT
Data transfers using DMA commands differ in two ways from PIO transfers:
• Data transfers are performed using the Slave DMA channel
• No intermediate sector interrupts are issued on multisector commands.
Initiation of the DMA transfer commands is identical to the Read Sector or Write Sector commands with one exception: the host initializes the Slave DMA channel prior to issuing the command.
The interrupt handler for DMA transfers differs in two ways:
• No intermediate sector interrupts are issued on multisector commands.
• The host resets the DMA channel prior to reading status from the device
The DMA protocol allows high performance multitasking operating systems to eliminate processor overhead associated with PIO transfers.
1. The host initializes the Slave DMA channel.
2. The host writes any required parameters to the Features, Sector Count, Sector Number, Cylinder, and
Device/Head registers.
3. The host writes command code to the Command Register.
4. The device sets DMARQ when it is ready to transfer any part of the data.
5. The host transfers the data using the DMA transfer protocol currently in effect.
6. When all of the data has been transferred, the device generates an interrupt to the host.
7. The host resets the Slave DMA channel.
8. The host reads the Status Register and, optionally, the Error Register.
Refer to Section 7.0, “Electrical interface specification” on page 39 for further details.

13.2.1 DEVICE CONFIGURATION RESTORE (subcommand C0h)
The DEVICE CONFIGURATION RESTORE command disables any setting previously made by a DEVICE
CONFIGURATION SET command and returns the content of the IDENTIFY DEVICE or IDENTIFY PACKET
DEVICE command response to the original settings as indicated by the data returned from the execution of a
DEVICE CONFIGURATION IDENTIFY command.
13.2.2 DEVICE CONFIGURATION FREEZE LOCK (subcommand C1h)
The DEVICE CONFIGURATION FREEZE LOCK command prevents accidental modification of the Device Configuration Overlay settings. After successful execution of a DEVICE CONFIGURATION FREEZE LOCK command, all DEVICE CONFIGURATION SET, DEVICE CONFIGURATION FREEZE LOCK, DEVICE
CONFIGURATION IDENTIFY, and DEVICE CONFIGURATION RESTORE commands are aborted by the device. The DEVICE CONFIGURATION FREEZE LOCK condition shall be cleared by a power-down. The
DEVICE CONFIGURATION FREEZE LOCK condition shall not be cleared by hardware or software reset.
Travelstar 80GN Hard Disk Drive Specification

13.2.3 DEVICE CONFIGURATION IDENTIFY (subcommand C2h)
The DEVICE CONFIGURATION IDENTIFY command returns a 512 byte data structure via PIO data-in transfer.
The content of this data structure indicates the selectable commands, modes, and feature sets that the device is capable of supporting. If a DEVICE CONFIGURATION SET command has been issued reducing the capabilities, the response to an IDENTIFY DEVICE or IDENTIFY PACKET DEVICE command will reflect the reduced set of capabilities, while the DEVICE CONFIGURATION IDENTIFY command will reflect the entire set of selectable capabilities.
13.2.4 DEVICE CONFIGURATION SET (subcommand C3h)
The DEVICE CONFIGURATION SET command allows a device manufacturer or a personal computer system manufacturer to reduce the set of optional commands, modes, or feature sets supported by a device as indicated by a DEVICE CONFIGURATION IDENTIFY command. The DEVICE CONFIGURATION SET command transfers an overlay that modifies some of the bits set in words 63, 82, 83, 84, and 88 of the IDENTIFY DEVICE command response. When the bits in these words are cleared, the device no longer supports the indicated command, mode, or feature set. If a bit is set in the overlay transmitted by the device that is not set in the overlay received from a
DEVICE CONFIGURATION IDENTIFY command, no action is taken for that bit.

The Format Unit command initializes all user data sectors after merging the reassigned sector location into the defect information of the device and clearing the reassign information. Both new reassign information and new defect information are available immediately after the completion of this command. They are also used on the next power on reset or hard reset. This command erases both previous information data from the device.
Note that the Format Unit command initializes from LBA 0 to Native MAX LBA. Host MAX LBA is set by Initialize Drive Parameter or Set MAX ADDRESS command is ignored. The protected area by Set MAX ADDRESS command is also initialized.
The Security Erase Prepare command should be completed immediately prior to the Format Unit command. If the device receives a Format Unit command without a prior Security Erase Prepare command, the device aborts the
Format Unit command.
If the Feature register is NOT 11h, the device returns an Abort error to the host.
This command does not request a data transfer.

When the power save mode is Standby mode, the Idle command causes the device to enter Performance Idle mode immediately and sets the auto power down time-out Parameter (standby timer). At the set of the auto power down time-out parameter (standby timer) the point timer starts counting down. When the power save mode is already any idle mode, the device remains in that mode.
When the Idle mode is entered, the device is spun up to operating speed. If the device is already spinning, the spin up sequence is not executed.
During Idle mode the device is spinning and is ready to respond to host commands immediately.
Input parameters to the device
Sector Count This indicates the Time-out Parameter. If it is zero, the time-out interval (Standby Timer) is NOT disabled and the time-out interval is set automatically for 109 minutes. If it is other than zero, the time-out interval is set for (Time-out Parameter × 5) seconds.
The device will enter Standby mode automatically if the time-out interval expires with no device access from the host. The time-out interval will be reinitialized if there is a device access before the time-out interval expires.

The Read DMA command reads one or more sectors of data from disk media and then transfers the data from the device to the host. It transfers the sectors through the Data Register 16 bits at a time.
The host initializes a slave-DMA channel prior to issuing the command. The data transfers are qualified by the
DMARQ and are performed by the slave-DMA channel. The device issues only one interrupt per command to indicate that the data transfer has terminated and that status is available.
If an uncorrectable error occurs, the read will be terminated at the failing sector.

The Read Long command reads the designated one sector of data and the ECC bytes from the disk media. It then transfers the data and ECC bytes from the device to the host.
After 512 bytes of data have been transferred, the device will keep setting DRQ = 1 to indicate that the device is ready to transfer the ECC bytes to the host. The data is transferred 16 bits at a time and the ECC bytes are transferred 8 bits at a time. The number of ECC bytes are 4 or 40 according to the setting of Set Feature option. The default setting is 4 bytes of ECC data.
The command makes a single attempt to read the data and does not check the data using ECC. Whatever is read is returned to the host.

The Security Erase Unit command initializes all user data sectors and then disables the device lock function.
Note that the Security Erase Unit command initializes from LBA 0 to Native MAX LBA. The Host MAX LBA is set by the Initialize Drive Parameter or the Set MAX ADDRESS command is ignored. The protected area by the
Set MAX ADDRESS command is also initialized.
This command requests the transfer of a single sector of data from the host including information specified in the table below.
If the password does not match, the device rejects the command with an Aborted error.

Identifier Zero indicates that the device should check the supplied password against the user password stored internally. One indicates that the device should check the given password against the master password stored internally.
The Security Erase Unit command erases all user data and disables the security mode feature (device lock function). After completing of this command, all the user data will be initialized to zero with a write operation. At this time, the data write is not verified with a read operation to determine if the data sector is initialized correctly. At this time the defective sector information and the reassigned sector information for the device are not updated. The security erase prepare command should be completed immediately prior to the Security Erase Unit command. If the device receives a Security Erase Unit command without a prior Security Erase Prepare command, the device aborts the security erase unit command.

This command disables the security mode feature (device lock function), however, the master password is still stored internally within the device and may be reactivated later when a new user password is set. If you execute this command on disabling the security mode feature (device lock function), the password sent by the host is NOT compared with the Master Password and the User Password. The device only erases all user data.

When the MASTER password is set by this command, the master password is registered internally. The device is NOT locked after next power on reset or hard reset.
This command requests a transfer of a single sector of data from the host including the information specified in the table below.
The data transferred controls the function of this command.

Security Level
A zero indicates a High level, a one indicates a Maximum level. If the host sets the High level and the password is forgotten then the Master Password can be used to unlock the device. If the host sets the Maximum level and the user password is forgotten, only a Security Erase Prepare/Security Unit command can unlock the device and all data will be lost.
Password
The 32 bytes are always significant in the text of the password.
Master Password Revision Code
The Revision Code field is set with Master password. If Identifier is User, the Revision Code is not set. The Revision Code field is returned in Identify Device word 92. The valid Revision Codes are 0000h to FFFDh. The Default
Master Password Revision Code is FFFEh. The code FFFFh is reserved.
The setting of the Identifier and Security level bits interact as follows:
Identifier = User / Security level = High
The password supplied with the command will be saved as the new user password. The security mode feature
(lock function) will be enabled from the next power on. The drive may then be unlocked by either the user password or the previously set master password.
Identifier = Master / Security level = High
This combination will set a master password but will NOT enable the security mode feature (lock function).
Identifier = User / Security level = Maximum
The password supplied with the command will be saved as the new user password. The security mode feature
(lock function) will be enabled from the next power on. The drive may then be unlocked by only the user password. The master password previously set is still stored in the drive but may NOT be used to unlock the device.
Identifier = Master / Security level = Maximum
This combination will set a master password but will NOT enable the security mode feature (lock function).

This command unlocks the password and causes the device to enter device unlock mode. If a power on reset or hard reset is done without executing the Security Disable Password command after this command is completed, the device will be in device lock mode. The password has not been changed yet.
The Security Unlock command requests to transfer a single sector of data from the host including information specified in the table below.
If the Identifier bit is set to master and the drive is in high security mode, the password supplied will be compared with the stored master password. If the drive is in maximum security mode, the security unlock will be rejected.
If the Identifier bit is set to user, the drive compares the supplied password with the stored user password.
If the password compare fails, the device returns an abort error to the host and decrements the unlock attempt counter. This counter is initially set to 5 and is decremented for each password mismatch. When this counter reaches zero, all password protected commands are rejected until there is a hard reset or a power off.

A zero indicates that the device regards Password as the User Password. A one indicates that the device regards
Password as the Master Password.
The user can detect if the attempt to unlock the device has failed due to a mismatched password since this is the only reason that an abort error will be returned by the drive AFTER the password information has been sent to the device. If an abort error is returned by the device BEFORE the password data has been sent to the drive, then another problem exists.

The Set Max ADDRESS command overwrites the max LBA/CYL of the drive in a range of actual device capacities. Once the device receives this command, all accesses beyond that LBA/CYL are rejected by setting the
ABORT bit in the status register. Identify the device command and Identify the device DMA command returns the
LBA/CYL which is set via this command as a default value.
This command implement SET MAX security extension commands as subcommands. But regardless of Feature register value, the case this command is immediately preceded by a Read Native Max ADDRESS command, it is interpreted as a Set Max ADDRESS command.
The Read Native Max ADDRESS command should be issued and completed immediately prior to issuing the Set
Max ADDRESS command. If it is not, this command is interpreted as a Set Max security extension command which is designated by feature register.
If Set Max security mode is in the Locked or Frozen, the Set Max ADDRESS command is aborted. For more infor-
mation, see section 11.10.2 “Set Max security extension commands” on page 84.
In CHS mode, LBA High and LBA Mid specify the maximum cylinder number. The Head number of DEVICE and
LBA Low are ignored. The default value (see default CHS in Identify device information) is used for that.
In LBA mode,the Head number of Device, LBA High, LBA Mid and LBA Low specify the max LBA. This command sets this LBA as the max LBA of the device.
After a successful command completion, Identify Device response words (61:60) shall reflect the maximum address set with this command.
If the 48-bit Address feature set is supported, the value placed in Identify Device response words (103:100) shall be the same as the value placed in words (61:60). However, if the device contains greater than 268,435,455 sectors, the capacity addressable with 28-bit commands, and the address requested is 268,435,455, the max address shall be changed to the native maximum address, the value placed in words (61:60) shall be 268,435,455 and the value placed in words (103:100) shall be the native maximum address.

This command is the only way to cause the device to enter Sleep Mode.
When this command is issued, the device confirms the completion of the cached write commands before it asserts
INTRQ. Then the device is spun down, and the interface becomes inactive. The only way to recover from Sleep
Mode is with a software reset or a hardware reset.
The use of hardware reset to recover from Sleep Mode may be incompatible with continued operation of the host system.
If the device is already spun down, the spin down sequence is not executed.

13.38.1 S.M.A.R.T. Function Subcommands
13.38.1.1 S.M.A.R.T. Read Attribute Values (subcommand D0h)
This subcommand returns the device's Attribute Values to the host. Upon receipt of the S.M.A.R.T. Read Attribute
Values subcommand from the host, the device asserts BSY, saves any updated Attribute Values to the Attribute
Data sectors, asserts DRQ, clears BSY, asserts INTRQ, and then waits for the host to transfer the 512 bytes of
Attribute Value information from the device via the Data Register.
13.38.1.2 S.M.A.R.T. Read Attribute Thresholds (subcommand D1h)
This subcommand returns the device's Attribute Thresholds to the host. Upon receipt of the S.M.A.R.T. Read
Attribute Thresholds subcommand from the host, the device asserts BSY, reads the Attribute Thresholds from the
Attribute Threshold sectors, asserts DRQ, clears BSY, asserts INTRQ, and then waits for the host to transfer the
512 bytes of Attribute Thresholds information from the device via the Data Register.
13.38.1.3 S.M.A.R.T. Enable/Disable Attribute Autosave (subcommand D2h)
This subcommand enables and disables the attribute auto save feature of the device. The S.M.A.R.T. Enable/Disable Attribute Autosave subcommand allows the device to automatically save its updated Attribute Values to the
Attribute Data Sector at the timing of the first transition to Active idle mode and after 30 minutes after the last saving of Attribute Values. This subcommand causes the auto save feature to be disabled. The state of the Attribute
Autosave feature—either enabled or disabled—will be preserved by the device across the power cycle.
A value of 00h—written by the host into the device's Sector Count Register before issuing the S.M.A.R.T. Enable/
Disable Attribute Autosave subcommand—will cause this feature to be disabled. Disabling this feature does not preclude the device from saving Attribute Values to the Attribute Data sectors during some other normal operation such as during a power-up or a power-down.
A value of F1h—written by the host into the device's Sector Count Register before issuing the S.M.A.R.T. Enable/
Disable Attribute Autosave subcommand—will cause this feature to be enabled. Any other nonzero value written by the host into this register before issuing the S.M.A.R.T. Enable/Disable Attribute Autosave subcommand will
“S.M.A.R.T. Error Codes” on page 175.
The S.M.A.R.T. Disable Operations subcommand disables the auto save feature along with the device's S.M.A.R.T. operations.
Upon the receipt of the subcommand from the host, the device asserts BSY, enables or disables the Autosave feature, clears BSY, and asserts INTRQ.
13.38.1.4 S.M.A.R.T. Save Attribute Values (subcommand D3h)
This subcommand causes the device to immediately save any updated Attribute Values to the device's Attribute
Data sector regardless of the state of the Attribute Autosave feature. Upon receipt of the S.M.A.R.T. Save Attribute
Values subcommand from the host, the device asserts BSY, writes any updated Attribute Values to the Attribute
Data sector, clears BSY, and asserts INTRQ.

Off-line mode: The device executes command completion before executing the specified routine. During execution of the routine the device will not set BSY nor clear DRDY. If the device is in the process of performing its routine and is interrupted by a new command from the host, the device will abort or suspend its routine and service the host within two seconds after receipt of the new command. After servicing the interrupting command, the device will resume its routine automatically or not start its routine depending on the interrupting command.
Captive mode: When executing self-test in captive mode, the device sets BSY to one and executes the specified self-test routine after receipt of the command. At the end of the routine, the device sets the execution result in the
ters—see definitions below—and then executes the command completion.

S.M.A.R.T.—either enabled or disabled—will be preserved by the device across power cycles. Once enabled, the receipt of subsequent S.M.A.R.T. Enable Operations subcommands will not affect any of the Attribute Values.
Upon receipt of the S.M.A.R.T. Enable Operations subcommand from the host, the device asserts BSY, enables
S.M.A.R.T. capabilities and functions, clears BSY, and asserts INTRQ.
13.38.1.9 S.M.A.R.T. Disable Operations (subcommand D9h)
This subcommand disables all S.M.A.R.T. capabilities within the device including the device's attribute auto save feature. After receipt of this subcommand the device disables all S.M.A.R.T. operations. Non self-preserved
Attribute Values will no longer be monitored. The state of S.M.A.R.T.—either enabled or disabled—is preserved by the device across power cycles. Note that this subcommand does not preclude the device's power mode attribute auto saving.
Upon receipt of the S.M.A.R.T. Disable Operations subcommand from the host, the device asserts BSY, disables
S.M.A.R.T. capabilities and functions, clears BSY, and asserts INTRQ.
After receipt of the device of the S.M.A.R.T. Disable Operations subcommand from the host, all other S.M.A.R.T. subcommands—with the exception of S.M.A.R.T. Enable Operations—are disabled, and invalid and will be aborted by the device—including the S.M.A.R.T. Disable Operations subcommand— returning the error code as
specified in Table 121: “S.M.A.R.T. Error Codes” on page 175.
Any Attribute Values accumulated and saved to volatile memory prior to receipt of the S.M.A.R.T. Disable Operations command will be preserved in the device's Attribute Data Sectors. If the device is re-enabled, these Attribute
Values will be updated, as needed, upon receipt of a S.M.A.R.T. Read Attribute Values or a S.M.A.R.T. Save
Attribute Values command.
13.38.1.10 S.M.A.R.T. Return Status (subcommand DAh)
This subcommand is used to communicate the reliability status of the device to the host's request. Upon receipt of the S.M.A.R.T. Return Status subcommand the device asserts BSY, saves any updated Attribute Values to the reserved sector, and compares the updated Attribute Values to the Attribute Thresholds.
If the device does not detect a Threshold Exceeded Condition, or detects a Threshold Exceeded Condition but involving attributes are advisory, the device loads 4Fh into the LBA Mid register, C2h into the LBA High register, clears BSY, and asserts INTRQ.
If the device detects a Threshold Exceeded Condition for prefailure attributes, the device loads F4h into the LBA
Mid register, 2Ch into the LBA High register, clears BSY, and asserts INTRQ. Advisory attributes never result in a negative reliability condition.
13.38.1.11 S.M.A.R.T. Enable/Disable Automatic Off-line (subcommand DBh)
This subcommand enables and disables the optional feature that cause the device to perform the set of off-line data collection activities that automatically collect attribute data in an off-line mode and then save this data to the device's nonvolatile memory. This subcommand may either cause the device to automatically initiate or resume performance of its off-line data collection activities or cause the automatic off-line data collection feature to be disabled. This subcommand also enables and disables the off-line read scanning feature that cause the device to perform the entire read scanning with defect reallocation as the part of the off-line data collection activities.

Normalized values: The device will perform conversion of the raw Attribute Values to transform them into normalized values which the host can then compare with the Threshold values. A Threshold is the excursion limit for a normalized Attribute Value. In normalizing the raw data, the device will perform any necessary statistical validity checks to ensure that an instantaneous raw value is not improperly reflected in the normalized Attribute Value (i.e., one read error in the first 10 reads being interpreted as exceeding the read error rate threshold when the subsequent
1 billion reads all execute without error). The end points for the normalized values for all Attributes will be 1 (01h) at the low end and 100 (64h) at the high end for the device. For Performance and Error Rate Attributes, values greater than 100 are also possible. The maximum value possible is 253 (FDh).
13.38.2.3 Off-Line Data Collection Status
The value of this byte defines the current status of the off-line activities of the device. Bit 7 indicates an Automatic
Off-line Data Collection Status.

The Standby command causes the device to enter the Standby Mode immediately and to set the auto power down time-out parameter (standby timer).
When this command is issued, the device confirms the completion of the cached write commands before it asserts the INTRQ. Following the INTRQ the interface remains active and the device is spun down. If the device is already spun down, the spin down sequence is not executed.
During the Standby mode the device will respond to commands, however there will be a delay while waiting for the spindle to reach operating speed.
The timer starts counting down when the device returns to Idle mode.
Output parameters to the device
Sector Count The Time-out Parameter. If it is zero, the time-out interval (Standby Timer) is NOT disabled but is automatically set to 109 minutes. If it is other than zero the time-out interval is set for (Time-out
Parameter × 5) seconds.
When the automatic power down sequence is enabled, the device will enter the Standby mode automatically if the time-out interval expires with no device access from the host. The time-out interval will be reinitialized if there is a device access before the time-out interval expires.

The Write Long command transfers the data and the ECC bytes of the designated one sector from the host to the device, then the data and the ECC bytes are written to the disk media.
After 512 bytes of data have been transferred, the device will keep setting DRQ = 1 to indicate that the device is ready to receive the ECC bytes from the host. The data is transferred 16 bits at a time and the ECC bytes are transferred 8 bits at a time. The number of ECC bytes are either 4 or 40 according to setting of the Set Feature option.
The default number after power on is 4 bytes.

The drive internally uses 40 bytes of ECC on all data read or writes. The 4-byte mode of operation is provided via an emulation technique. As a consequence of this emulation it is recommended that 40 byte ECC mode is used for all tests to confirm the operation of the ECC hardware of the drive. Unexpected results may occur if such testing is performed using 4-byte mode.
