4 DC power Interface

4.1 DC Power Requirement
The drives are operated on DC power (+5V, +12V) only.
No power sequencing is required.
The +5 and +12 Volts can be applied in any order.

Table 4.1 DC Power Requirement

Power supply Voltage tolerance Allowed ripple and noise

+5V DC 5.0V +/-5% Less than 150mVp-p (0 - 100kHz)

Less than 100mVp-p (100kHz - 10MHz)

+12V DC 12.0V +/-5% Less than 150mVp-p (0 - 100kHz)

Less than 100mVp-p (100kHz - 10MHz)

Note 1. Voltage tolerance is measured at the DC power connector on the PCB.

The ripple current occurs during the motor start-up and seek.
Appropriate size of the DC Power cable is recommended to reduce the above
ripple and noise.

Note 2. In case of fluctuations in the DC power (spikes, momentary shut off, etc.), the

data being recorded or to be recorded from buffer memory are not assured.

Note 1. Start time means that the time of becoming ready, after DC power has been

applied in the case of Enable Auto Start mode, or after Start Unit command
(immed=0) has accepted in other case. If internal retry is executed during the Start­up operation, the Start time may exceed typical value. It is recommended to have 60
seconds for the Start time. In the case of a spindle start-up failure, the time of an
internal retry operation is 130 seconds maximum.

Caution

Note 2. Beginning of stop time is basically decided by +12v DC power off.
In case of +5v DC power off only, stop time is 65sec(typ).

Do not move the drive until motor stop completely.

Stop time means that the time to stop the spindle rotation, after DC power has

been shut off, or after stop operation has started.

4.3.2 Spindle Start Selection
When multiple disk drives are connected to the same power supply and turned on
simultaneously, a large current will be required at power up.
In the above case, it is recommended to turn the motors on one by one at intervals in
order to minimize 12V line current.

This can be done according to the following 3 jumper pin configurations in the case of
NW drive:

1. If Disable Auto Start mode is set (C3:9-10 installed);

(1) Use a spindle start command for each drive, issuing it to the next drive after

receiving the previous drive’s Ready condition.
or
(2) Use the spindle start command for each drive, issuing it at intervals of more than

10 seconds.

2. If Enable Auto Start mode is set (C3:9-10 removed) and Spindle Start at Power On
is set (C3:13-14 removed);
Manually power on drives at intervals of more than 10 seconds.

3. If Enable Auto Start mode is set (C3:9-10 removed) and Delayed Start is set (C3:13­14 installed);
Upon power on condition, the drives will automatically spin up in 10 second intervals
according to their SCSI ID. (The drive with the lowest SCSI ID will start first.)
In the case that their SCSI ID are more than 7, the drives will automatically spin up in
10 second intervals according to the numbers of (SCSI ID minus 8).

Note 1 The Delayed Start setting and the Auto Start setting can be done by commands

from host via SCSI bus connector (C1) in the case of NC drive.

5.2 Low voltage differential (LVD) mode

The NW and NC drives have two different transceivers to allow customer to use it in
traditional systems which may use single-ended drivers and receivers, or to use it in
low voltage differential (LVD) systems which use LVD drivers and receivers.
Their I/O circuits are selectable using the I/O "DIFFSENS" line. When the I/O
"DIFFSENS" line is between -0.35V and +0.5V, the drive interface circuits operate
single-ended. When "DIFFSENS" is between +0.7V and +1.9V, the drive interface
circuits operate LVD.
Customer can configure the drive to switch between single-ended and LVD modes
using the I/O "DIFFSENS" line, or force it to operate in single-ended mode only as
described later in this document.

Note 1: To operate at LVD mode, all devices on the same bus must be running in LVD

mode. If you add any single-ended device to a bus that is operating in LVD mode,
all devices drop back to operating in single-ended mode. This eliminates the
possibility of reaching Ultra-2 SCSI transfer rates.

Note 2: Do not mix LVD drives on the same daisy chain with devices having high voltage

differential (HVD) interface circuits.

6 SCSI Interface

6.1 Summary of SCSI Controller
The Ultrastar 15K73 SCSI controller interfaces between the drive and the host
computer with the Small Computer System Interface (SCSI).

(1) ANSI standard

The controller supports the SCSI interface that conforms to the ANSI specifications
shown in section 2.

(2) Compact design

The controller is embedded within the disk drive.

(3) Fast data transfer rate

The controller can transfer data via asynchronous mode, Fast-5 synchronous mode,
Fast-10 synchronous mode and Ultra (Fast-20) synchronous mode.
The controller can transfer data via Ultra2 (Fast-40) synchronous mode and Ultra160
(Fast-80) synchronous mode and Ultra320 (Fast-160) synchronous mode, as well as
above-mentioned transfer mode.

(4) FIFO buffer

The Ultrastar 15K73 SCSI controller has 8M bytes of FIFO buffer. This data buffering
feature prevents the SCSI controller from delay during the reconnect process and
reduces the latency time that is generated by the difference of the data transfer rate
between media and host.

(5) Automatic error retry

The controller automatically retries whenever the disk drive encounters errors.

(6) Automatic error corrections

The controller uses 40 bytes ECC and On-The-Fly to automatically correct read
errors, without latent rotational time.

(7) Parameter save feature

The controller saves the controller/device parameters (MODE SELECT parameters)
specified by the host onto the disk drive. The parameters are automatically restored at
power-on time.

Drawing No. Sheet No. Revision 5

K6602906 20/46 2003/6/12

(8) Tagged Command Queuing

A maximum of 110 commands can be enqueued to this drive. The drive does not have
to connect and disconnect to the host controller even if the SCSI command has been
issued successively, so the overhead time of the SCSI bus can be reduced.

(9) S.M.A.R.T. (Self - Monitoring, Analysis and Reporting Technology)

This function helps predict a failure related to the degradation of the disk drive itself.
For users seeking to use the drive as long as possible, S.M.A.R.T. can be used to
predict when failure might occur. The user can use this information to back-up the data
before failure.
The S.M.A.R.T. report is written on the disk at regular intervals that are not based on
drive usage.

(10) Automatic Read Reallocation

When an error is detected on reading the data, this function automatically assigns an
alternate sector in place of the defective sector and stores the data on the alternated
sector.

(11) Write Cache

The controller can return a completion of a WRITE command with a GOOD status after
receiving the data from the host but before writing the data from its buffer to the media.
The Deferred Error function reports an Disk Access Error to the host computer if an
error occurs when the data are being stored on the disk medium after the GOOD status
was already returned. In this case, any data still in the buffer (not yet written to the
media) is not assured.

(12) Log Save

Diagnostic information is written on the disk at regular intervals that are not based on
drive usage.

7.4 Precautions on the off-line test or bench test
When the off-line test or bench test is performed the drive should be tightly fixed
and cooled. The set-up should be similar to the actual system configuration.

7.5 Cooling of the drive
Keep the drive (HDA and PCB) cool by using a FAN. Reliability and life of the drive
increases as the temperature is lower.

Caution

7.6 Reliability temperature
The temperature measurement points and temperature limits are shown below.

1. The maximum temperature assures the data reliability, seek error rate, and must not

be exceeded.

2. The reliability temperature maintains the MTBF of the drive and must not be

exceeded in order to ensure its reliability. MTBF is also based on a nominal voltage
condition.

3. The maximum temperature of HDA includes momentary temperature rise. Average

temperature of HDA has to be less than this temperature.

Caution

8 Precautions for handling

The drive is sensitive to shock, vibration, over voltage, temperature, humidity,
corrosive gas, magnetic force and electrostatic discharge.
If these forces contact the electrical or mechanical components (magnetic heads,
magnetic disks), the drive will break down, degrade, or storage data will be lost.
The following handling guidelines are mandatory.
(1) Handle the drive on the appropriate cushion (for example, anti-static pad with

thickness of 10mm or more) to prevent from shock and vibration.

(2) Handle the drive with a wrist band, an anti-static mat, or without direct touch of the

hands to the PCB in order to prevent static electricity discharge.

(3) Handle the drive in an environment (Temperature, Moisture, Corrosive gas), which

follows the drive specification and prevents unforeseen complications.

8.1 Packing
After cleaning the drive, pack it in the following manner to protect it from moisture.
(1) Put the drive in an electro-static shielding bag with desiccant.
(2) Packing materials, i.e. electro-static shielding bag, cardboard box, cushion, etc.,
should not contain corrosive gas, saline or organic-metal compound. (Example
organic silicon, organic tin)
(3) If the package has no damage after unpacking, reserve it for storage or
Transportation of the drive.
But 20-unit packing material is suitable for only 20 units packing.
When less than 19 units, it is recommended to use the 5-unit packing material.
5-units packing material covers the quantity from 1 to 5.

8.2 Transportation
(1) Pack the drive so as to maintain above-mentioned environmental conditions during

transportation. (Refer to section 4.2)

(2) When you take the drive out of the packing case and carry it on a hand truck, lay it

on cushioning material (for example, urethane foam cushioning with a thickness of
10mm or more).

8.3 Storage
When storing, pack the drive to protect it against moisture. (Refer to section 4.2)
In case that storage period becomes long, exchange a desiccant and repack.
This operation shall be executed every 3 months.

8.4 Other Precautions

8.4.1 Do not loosen the screws or disassemble the drive.

8.4.2 Do not remove the PCB from the drive or swap the PCB with other drives.

8.4.3 Do not solder the wire or other parts on the PCB, or reconstruct the PCB.

8.4.4 Do not remove the sealing tape or label on the HDA.

8.4.5 Turn off the power before removing or installing the DC power cable and

SCSI interface cable. Turn off the power before removing or installing the jumper.

8.4.6 Remove the DC power and SCSI interface connectors carefully in order

not to damage the contact pins and the connector housing.

8.4.7 Do not move the drive when the disks are rotating or while the power is

on or for 20 seconds after the power has been turned off.

9.4.8 Do not cover the breathing hole on the surface of the drive with use of a seal. (The

position of the breathing hole is shown in Figure 8.4.)

9 Maintenance

9.1 The HDD itself is maintenance free and there are no individual parts that require
maintenance. If maintenance for the HDD is required, the entire product will need to
be serviced, since it can not be divided into parts. System maintenance should be
executed by the host system.

9.2 The supplier will repair or exchange the product due to malfunction covered under
the warranty. The warranty and service will be agreed upon between the customer
and the supplier. The supplier is neither liable or obligated to service any product
due to carelessness or mishandling of product.

9.3 Even if the drive fault occurs during the In-warranty period, the supplier will repair or
replace the drive but will not be liable for any expenses of disk drive installation or
detachment to or from system. (This includes data back up, data copy, etc.)

10.2 Cable Specifications

(1) SCSI Interface Cable

Use interface cables that meet the ANSI SCSI guideline.
The total cable length must be within the maximum cable length in case multiple drives
are daisy chained. Specifications of maximum cable length are shown in Table 10.2
and Table 10.3.
The length of a cable connected between SCSI devices must be a minimum of
12 cm. (The stub length of the drive: 4 cm)
If an external cable the stub length of which becomes long is connected
to the devices, the cable length between the devices must be a minimum of
(external stub length + 4 cm) x 3.
If data are transferred by Ultra SCSI (Fast-20) mode, Ultra2 SCSI (Fast-40) mode,
Ultra160 SCSI (Fast-80) mode or Ultra320 SCSI (Fast-160) mode, check that the
interface reflection noise does not influence the motion of the drive in the actual user’s
system.
