3.0 Fixed disk subsystem description
3.1 Control Electronics
The drive is electronically controlled by a microprocessor, several logic modules, digital/analog modules, and
various drivers and receivers. The control electronics performs the following major functions:
• Controls and interprets all interface signals between the host controller and the drive.
• Controls read write accessing of the disk media, including defect management and error recovery.
• Controls starting, stopping, and monitoring of the spindle.
• Conducts a power-up sequence and calibrates the servo.
• Analyzes servo signals to provide closed loop control. These include position error signal and estimated
velocity.
• Monitors the actuator position and determines the target track for a seek operation.
• Controls the voice coi l motor driver to align the actuator in a desired position.
• Constantly monitors error conditions of the servo and takes corresponding action if an error occurs.
• Monitors various timers such as head settle and servo failure.
• Performs self-checkout (diagnostics).
3.2 Head disk assembly
The head disk assembly (HDA) is assembled in a clean room environment and contains the disks and actuator
assembly. Air is constantly circulated and filtered when the drive is operat ional. Venting of the HDA is
accomplished via a breather filter.
The spindle is driven directly by an in-hub, brushless, sensorless DC drive motor. Dynamic braking is used to
quickly stop the spindle.
3.3 Actuator
The read/write heads are mounted in the actuator. The actuator is a swing-arm assembly driven by a voice coil
motor. A closed-loop positioning servo controls the movement of the actuator. An embedded servo pattern
supplies feedback to the positioning servo to keep the read/write heads cent ered over the d esired track.
The actuator assembly is balanced to allow vertical or horizontal mounting without adjustment.
When the drive is powered off, the actuator automatically moves the head to the actuator ramp outside of the
disk where it parks.

4.5 Performance characteristics
Drive performance is characterized by the following parameters:
Command overhead
Mechanical positioning
- Seek time
- Latency
Data transfer speed
Buffering operation (Look ahead/Write cache)
All the above parameters contribute to drive performance. There are other parameters that contribute to the
performance of the actual system. This specification defines the characteristics of the drive, not the
characteristics of the system throughput which depends on the system and the application.
4.5.1 Command overhead
Command overhead is defined as the time required
from the time the command is written into the command register by a host to the assertion of DRQ for the first data byte of a READ command when the requested data is no t
in the buffer
excluding Physic al seek time and Latency
The table below gives average command overhead.
Command type (Drive is in quiescent state)
Read (Cache not hit) (from Command Write to Seek Start) 0.5 0.5
Read (Cache hit) (from Command Write to DRQ) 0.1 0.2

Table 5 Mechanical positioning performance
The terms “Typical” and “Max” are used throughout this specification with the following meanings:
Typical. The average of the drive population tested at nominal environmental and voltage
conditions.
Max. The maximum value measured on any one drive over the full range of the environmental and
voltage conditions. (See Section 6.4, “Environment” on page 41 and Section 6.5, “DC Power
Requirements” on page 43.
Seek time is measured from the start of the motion of the actuator to the start of a reliable read or write operation. "Reliable read or write" implies that error correction/recovery is not used to correct
arrival problems. The average seek time is measured as the weighted average of all possible seek
combinations.

5.0 Defect flagging strategy
Media defects are remapped to the next available sector during the Format Process in manufacturing. The
mapping from LBA to the physical locations is calculated by an internally maintained table.
Shipped format
• Data areas are optimally used.
• No extra sector is wasted as a spare throughout user data areas.
• All pushes generated by defects are absorbed by the spare tracks of the inner zone.

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

DD0-DD15 16-bit bi-directional data bus between the host and the drive. The lower 8 lines, DD00-07,
are used for Register and ECC access. All 16 lines, DD00-15, are used for data transfer.
These are 3-State lines with 24 mA current sink capability.
DA0-DA2 Address used to select the individu al register in the drive.
CS0- Chip select signal generated from the Host address bus. When active, one of the Command
Block Registers (Data, Error {Features when written}, Sector Count, Sector Number,
Cylinder Low, Cylinder High, Drive/Head and Status {Command when written} register) can
be selected. (See Table 26: "I/O address map" on page 34)
CS1- Chip select signal generated from the Host address bus. When active one of the Control
Block Registers (Alternate Status {Device Control when written}) can be selected. (See
Table 26: "I/O address map" on page 34)
RESET- This line is used to reset the drive. It shall be kept in Low logic state during power up and in
High thereafter.
DIOW- Its rising edge holds data from the host data bus to a register or data register of the drive.
DIOR- When low, this signal enables data from a register or data register of the drive o nto data bus.
The data on the bus shall be latched on the rising edge of DIOR-.
INTRQ Interrupt is enabled only when the drive is selected and the host activates the nIEN bit in the
Device Control Reg. Otherwise, this signal is in high impedance state regardless of the state
of the IRQ bit. The interrupt is set when the IRQ bit is set by the drive CPU. IRQ is reset to
zero by a host read of the status register or a write to the Command Reg. This signal is a
3-State line with 24 mA sink capability.
DASP- This is a time-multiplexed signal which indicates that a drive is active, or that device 1 is
present. This signal is driven by Open-Drain driver and internally pulled up to 5 volts through
a 10kΩ resistor.
During Power-On initialization or after RESET- is negated, DASP- shall be asserted by
Device 1 within 400 ms to indicate that device 1 is present. Device 0 shall allow up to 450
ms for device 1 to assert DASP-. If device 1 is not present, device 0 may assert DASP- to
drive a LED indica t or.
DASP- shall be negated following acceptance of the first valid command by device 1. At
anytime after negation of DASP-, eithe r drive may assert DASP- to in dicate that a drive is
active.
PDIAG- PDIAG- shall be asserted by device 1 to indicate to device 0 that it has completed
diagnostics. This line is pulled-up to 5 vo lts in the dri ve through a 10k Ω 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 stat us.
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, 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 tha t device 1 has pa ssed
its diagnos tics and is ready to post status.
If device 1 did not assert DASP- during reset initialization, device 0 shall post its own status
immediatel y after it completes dia gnostics an d clear the device 1 Stat us register to 00h.
Device 0 may be unable to accept commands until it has finished its reset procedure and is
ready (DRDY=1).
Device 1 shall release PDIAG-/CBLID- no later than after the first command following a
power on or hardware reset se q ue nce so th at th e ho st ma y sa mple PDI AG-/CBLID- in order
to detect the presence or absence of an 80-conductor cable assembly.
HITACHI Deskstar & CinemaStar P7K500 Hard Disk Drive specification (Rev 1.1)

CSEL (Cable Select) (Optional)
The drive is configured as either Device 0 or 1 depending upon the value of CSEL.
• If CSEL is grounded, the device address is 0.
• If CSEL is open , the device address is 1.
KEY Pin position 20 has no connection pin. It is recommended to close the respective position of
the cable connector in order to avoid incorrect insertion by mistake.
IORDY This signal is negated to extend the host transfer cycle when a drive is not ready to respond
to a data transfer request and may be negated when the host transfer cycle is less than 240
ns for PIO data transfer. This signal is an open-drain output with 24 mA sink capability and
an external resistor is needed to pull up this line to 5 volts.
DMACK- This signal shall be used by the host in response to DMARQ to either acknowledge that data
has been accepted or that data is available.
This signal is internally pulled up to 3.3 V through a 15 KΩ resistor. The t ole r a n ce of the
resistor value is –50% to +100%.
DMARQ This signal, used for DMA data transfers between host and drive, shall be asserted by the
drive when it is ready to transfer data to or from the host. The direction of data transfer is
controlled by DIOR- and DIOW-. This signal is used on a handshake manner with DMACK-.
This signal is a 3-state line with 24mA sink capability and internally pulled down to GND
through 10 KΩ resistor.
HDMARDY- (Ultra DMA)
This signal is used only for Ultra DMA data transfers between the host and the device.
HDMARDY- is a flow control signal for Ultra DMA data in bursts. This signal is held asserted
by the host to indicate to the device that the host is ready to receive Ultra DMA data in
transfers. The host may negate HDMARDY- to pause an Ultra DMA data in transfer.
HSTROBE (Ultra DMA)
This signal is used only for Ultra DMA data transfers between the host and the device.
HSTROBE is the data out strobe signal from the host for an Ultra DMA data out transfer.
Both the rising and falling edge of HSTROBE latch the data from DD(15:0) into the device.
The host may stop toggling HSTROBE to pause an Ultra DMA data out transfer.
STOP (Ultra DMA)
This signal is used only for Ultra DMA data transfers between the host and the device.
STOP shall be asserted by the host prior to initiati on of an Ultra DMA burst. STOP shall be
negated by the host before data is transferred in an Ultra DMA burst. Assertion of STOP by
the host during or after data transfer in an Ultra DMA mode signals the termination of the
burst.
DDMARDY- (Ultra DMA)
This signal is used only for Ultra DMA data transfers between the host and the device.
DDMARDY- is a flow control signal for Ultra DMA data out bursts. This signal is held
asserted by the device to indicate to the host that the device is ready to receive Ultra DMA
data out transfers. The device may negate DDMARDY- to pause an Ultra DMA data out
transfer.
DSTROBE (Ultra DMA)
This signal is used only for Ultra DMA data transfers between the host and the device.
DSTROBE is the data in strobe signal from the device for an Ultra DMA data in transfer.
Both the rising and falling edge of DSTROBE latch the data from DD(15:0) into the host. The
device may stop toggling DSTROBE to pause an Ultra DMA data in transfer.
Device Termination
The termination resistors on the device side are implemented on the drive side as follows:
