Hard Disk Drive Specification

3 Fixed disk subsystem description

Control Electronics

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

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

velocity.

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

Head disk assembly

The head disk assembly (HDA) is assembled in a clean room environment and contains the disks and actuator
assembly. Helium is constantly circulated and filtered when the drive is operational. No venting of the HDA is
accomplished, as HDA is hermetically sealed.

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

Actuator

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

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

where it parks.

Notes:

1

Logical layout: Logical layout is an imaginary drive parameter (that is, the number of heads) which is used to
access the drive from the system interface. The Logical layout to Physical layout (that is, the actual Head and
Sectors) translation is done automatically in the drive. The default setting can be obtained by issuing an
IDENTIFY DEVICE command

Drive organization

Drive Format

Upon shipment from Western Digital manufacturing the drive satisfies the sector continuity in the physical format
by means of the defect flagging strategy described in Section 5 in order to provide the maximum performance to
users.

Cylinder allocation

Physical cylinder is calculated from the starting data track of 0. It is not relevant to logical CHS. Depending on the
capacity some of the inner zone cylinders are not allocated.

Data cylinder
This cylinder contains the user data which can be sent and retrieved via read/write commands and a spare area
for reassigned data.

Spare cylinder
The spare cylinder is used by Western Digital manufacturing and includes data sent from a defect location.

Zone Layout

The LBAs are divided into ranges called zones.
The entire capacity of a zoned block device is organized into a set of contiguous, non-overlapping zones.

Zone size 256MiB
Conventional Zone 1% of Total Capacity
Sequential write required zone 99% of Total Capacity

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.

Command overhead

Command overhead is defined as the time required
From the time

To the time

- PIO Set Up FIS is sent by device (PIO Read/Write)

- DATA FIS is sent by device (DMA Read)

- DMA Activate FIS is sent by device (DMA Write)

- DMA Set Up FIS is sent by device (NCQ Read/Write)

- Seek Start (Read cache not hit or Seek)

Table 7 Average seek time

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 6.2, “Environment” and Section 6.3, “DC Power Requirements”)

Single track seek time (without command overhead, including

settling)

Notes: The typical and maximum drive ready time in the table are for proper power shutdown using the Required
Power-Off Sequence. In the event of an EPO (Emergency Power Off), the drive ready times in the table can be
exceeded by as much as 4-12 seconds or more. The additional time is used to condition the drive for user data
access. The actual time may vary depending on the drive pre-condition before the EPO event.

5 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.

Figure 2 PList physical format

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

Connector location

Refer to the following illustration to see the location of the connectors.

Figure 3 Connector location

Signal connector

A Serial ATA device may be either directly connected to a host or connected to a host through a cable.
For direct connection, the device plug connector is inserted directly into a backplane connector. The device plug

connector and the backplane connector incorporate features that enable the direct connection to be hot pluggable
and blind mateable.

For connection via cable, the device signal plug connector mates with the signal cable receptacle connector on one
end of the cable. The signal cable receptacle connector on the other end of the cable is inserted into a host signal
plug connector. The signal cable wire consists of two twinax sections in a common outer sheath.

Besides the signal cable, there is also a separate power cable for the cabled connection. A Serial ATA power cable
includes a power cable receptacle connector on one end and may be directly connected to the host power supply
on the other end or may include a power cable receptacle on the other end. The power cable receptacle connector
on one end of the power cable mates with the device power plug connector. The other end of the power cable is
attached to the host as necessary.

Signal definition

SATA has receivers and drivers to be connected to Tx+/- and Rx +/- Serial data signal.
Defines the signal names of I/O connector pin and signal name.

Table 12 Interface connector pins and I/O signals

* SATA Specification Revision 3.1 and prior revisions assigned 3.3V to pins P1, P2 and P3. In addition, device
plug pins P1, P2, and P3 were required to be bused together. In the standard configuration of this product,
P3 is connected with P1 and P2 and this product behaves as SATA 3.1 or prior version product in a system
designed to SATA 3.2 system that does not support the 3.3 feature. For product with the optional SATA 3.3
Power Disable Feature supported, P3 is now assigned as the POWER DISABLE CONTROL PIN. If P3 is driven
HIGH (2.1V-3.6V max), power to the drive circuitry will be disabled. Drives with this optional feature WILL NOT
POWER UP in systems designed to SATA Spec Revision 3.1 or earlier because P3 driven HIGH will prevent the
drive from powering up.

TX+ / TX-

These signals are the outbound high-speed differential signals that are connected to the serial ATA cable
