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.

Notes:

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

use
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 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.

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 of the inner zone.

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.

Table 15 Power supply generated ripple at drive power connector
During drive start up and seeking 12-volt ripple is generated by the drive (referred to as dynamic loading). If the power of several drives is daisy chained together, the power supply ripple plus the dynamic loading of the other drives must remain within the above regulation tolerance. A common supply with separate power leads to each drive is a more desirable method of power distribution.
To prevent external electrical noise from interfering with the performance of the drive, the drive must be held by four screws in a user system frame which has no electrical level difference at the four screws position and has less than ±300 millivolts peak to peak level difference to the ground of the drive power connector.
HGST hard disk drive specifications

6.4 Reliability
6.4.1 Data integrity
No more than one sector is lost at Power loss condition during the write operation when the write cache option is disabled. If the write cache option is active, the data in write cache will be lost. To prevent the loss of customer data, it is recommended that the last write access before power off be issued after setting the write cache off.
6.4.2 Cable noise interference
To avoid any degradation of performance throughput or error rate when the interface cable is routed on top or comes in contact with the HDA assembly, the drive must be grounded electrically to the system frame by four screws. The common mode noise or voltage level difference between the system frame and power cable ground or AT interface cable ground should be in the allowable level specified in the power requirement section.
6.4.3 Load/Unload
The product supports a minimum of 600,000 normal load/unloads in a 40° C environment. Load/unload is invoked by transition of the HDD's power mode.
Idle <-> unload idle Idle <-> Low rpm idle
6.4.4 Start/stop cycles
The drive withstands a minimum of 50,000 start/stop cycles in a 40° C environment and a minimum of 10,000 start/stop cycles in extreme temperature or humidity within the operating range. .
