1.3General Caution

Do not apply force to the top cover. Handle the drive by its edges or frame only. Do not touch the interface connector pins or the surface of the printed circuit board.

The drive can be damaged by shock or ESD (Electrostatic Discharge). Any damage sustained by the drive after removal from the shipping package and opening the ESD protective bag are the responsibility of the user.

3 Fixed Disk Subsystem Description

3.1Control Electronics

The drive is electronically controlled by a microprocessor, several logic modules, digital/analog modules, and various drivers and receivers. The control electronics perform 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 and secondary actuator drivers 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).

3.2Head Disk Assembly

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

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

3.3Actuator

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.

4.4.2Cylinder 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 WDC manufacturing and includes data sent from a defect location.

4.5Performance 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.

The terms “Typical” and “Max” are used throughout this specification with

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,Section“Environment”6.3, “DCandPower )Requirements”

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.

5.1Shipped 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.

N	N+1	defect	N+2	defect	N+3
		skip		skip

Figure 1 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.

Western Digital Hard Disk Drive OEM Specification

6.1.1.1 Signal Connector (SATA)

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 mated.

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.

Table 11 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.
