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 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).

3.2Head 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.

3.3Actuator

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 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

4.4.1Drive Format

Upon shipment from HGST manufacturing the drive satisfies the sector continuity in the physical format by means of the defect flagging strategy described in Section 5 on page 22 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 HGST manufacturing and includes data sent from a defect location.

HGST hard disk drive specifications 18

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.

4.5.1Command 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.

Command type	Typical time (ms)	Typical time for NCQ
(Drive is in quiescent state)		command (ms)
Read (Cache not hit)	0.5	0.5
Read (Cache hit)	0.1	0.2
Write	0.015	0.2
Seek	0.5	not applicable

Table 5 Command overhead

HGST hard disk drive specifications 19

4.5.2Mechanical positioning

4.5.2.1Single track seek time (without command overhead, including settling)

Common to all models and all seek modes

Function	Typical (ms)	Max (ms)
Read	0.5	0.7
Write	0.6	0.8

HGST hard disk drive specifications 20

4.5.4Operating modes

4.5.4.1Operating mode descriptions

Operating mode	Description
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 and wake up for 100us
	every 10 revolutions. 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.

4.5.4.2Mode transition times

Mode transition times are shown below.

	From	To	RPM	Typical Transition	Max Transition
				time(sec)	time(sec)
	Standby	Idle	0 -> 7200	15	30
	Idle	Standby	7200 -> 0	Immediately	Immediately
	Standby	Sleep	0	Immediately	Immediately
	Sleep	Standby	0	Immediately	Immediately
	Unload idle	Idle	7,200	1	30
	Idle	Unload Idle	7,200	Immediately	Immediately
	Low RPM Idle	Idle	6300 -> 7200	4	30

Note:

The command is processed immediately but there will be an actual spin down time reflecting the seconds passed until the spindle motor stops.

Table 9 Mode transition times

HGST hard disk drive specifications 21

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.

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.

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.

6.4Reliability

6.4.1Data 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.

6.4.2Cable 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.

6.4.3Load/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

6.4.4Start/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. .
