3 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 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).
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 operational. 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 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.

This section describes the characteristics of the drive.
4.1 Default logical drive parameters
The default of the logical drive parameters in Identify Device data is as shown below.
Table 2 Formatted capacity (512emulation)
Table 3 Formatted capacity (4Knative)
Notes:
1
Number of cylinders: For drives with capacities greater an 8.45 GB the IDENTIFY DEVICE information word 01
limits the number of cylinders to 16,383 per the ATA specification.
2
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

4.4.1 Drive Format
Upon shipment from HGST Japan manufacturing the drive satisfies the sector continuity in the physical format by means of the defect flagging strategy described in Section 5 on page 25 in order to provide the maximum performance to users.
4.4.2 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 HGST Japan manufacturing and includes data sent from a defect location.
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 H->D Reg FIS w/ command bit is sent by host 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)
The table below gives average command overhead.

4.5.2.1 Average seek time (without command overhead, including settling)
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”)

settling)

Spin-up Start up time period from spindle stop or power down Seek Seek operation mode Write Write operation mode Read Read operation mode Unload Idle Spindle rotation at 7200 RPM with heads unloaded Idle Spindle motor is working normally. Servo system is sleeping or waking up. Commands
can be received and processed immediately
Standby Actuator is unloaded and spindle motor is stopped. Commands can be received
immediately
Sleep Actuator is unloaded and spindle motor is stopped. Only soft reset or hard reset can
change the mode to standby
Note: Upon power down or spindle stop a head locking mechanism will secure the heads in the OD parking position.

skip
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.
5.1 Shipped format
Data areas are optimally used. No extra sector is wasted as a spare throughout user data areas. (SATA) All pushes generated by defects are absorbed by the spare tracks of the inner zone.
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.

Notes:
1. The system is responsible for providing sufficient ventilation to maintain a surface temperature below 65°C at
the center of the top cover of the drive.
2. Non condensing conditions should be maintained at any time.
3. Maximum storage period within shipping package is one year.

6.2.2 Corrosion test
The drive shows no sign of corrosion inside and outside of the hard disk assembly and is functional after being subjected to seven days at 50°C with 90% relative humidity.
6.2.3 Atmospheric condition
Environments that contain elevated levels of corrosives (e.g. hydrogen sulfide, sulfur oxides, or hydrochloric acid) should be avoided. Care must be taken to avoid using any compound/material in a way that creates an elevated level of corrosive materials in the atmosphere surrounding the disk drive. Care must also be taken to avoid use of any organometallic (e.g. organosilicon or organotin) compound/material in a way that creates elevated vapor levels of these compounds/materials in the atmosphere surrounding the disk drive.

Damage to the drive electronics may result if the power supply cable is connected or disconnected to the legacy Power connector while power is being applied to the drive (no hot plug/unplug is allowed). If SATA power supply cable is connected or disconnected to the SATA power connector, hot plug/unplug is allowed.
