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.

4.4Drive Organization
4.4.1Drive Format
Upon shipment from WDC manufacturing, the drive satisfies the sector continuity in the physical format by means of the defect flagging strategy described in Section 5 on page 13 in order to provide the maximum performance to users.
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 th
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.
