Conventions for Alert Messages

This manual uses the following conventions to show the alert messages. An alert message

consists of an alert signal and alert statements. The alert signal consists of an alert symbol

and a signal word or just a signal word.

The following are the alert signals and their meanings:

This indicates a hazardous situation likely to result in

serious personal injury if the user does not perform the

procedure correctly.

This indicates a hazardous situation could result in serious

personal injury if the user does not perform the procedure

correctly.

This indicates a hazardous situation could result in minor

or moderate personal injury if the user does not perform

the procedure correctly. This alert signal also indicates

that damages to the product or other property, may occur if

the user does not perform the product correctly.

This indicates information that could help the user use the

product more efficiently.

In the text, the alert signal is centered, followed below by the indented message. A wider

line space precedes and follows the alert message to show where the alert message begins

and ends. The following is an example:

(Example)

Data loss

For MAS series, Reed Solomon codes are applied for their ECC. The

sector-data is divided into 4 interleaving sectors, and ECC is performed in

each sector where the maximum number of errors (up to 5 byte) can be

corrected. [Total maximum byte: 5 byte ×4 ( interleave) = 20 byte]

If the error of read sector keeps allowable error byte number, correction is

performed. However, if error byte exceeds its allowable number,

correction may not be performed properly.

The main alert messages in the text are also listed in the “Important Alert Items.”

CONVENTIONS USED IN THIS MANUAL

The MAS3735FC and MAS3367FC disk drives are described as "the intelligent disk drive

(IDD)", "the drive" or "the device" in this manual.

Decimal number is represented normally.

Hexadecimal number is represented as X'17B9', 17B9h or 17B9H.

Binary number is represented as "010".

Hot temperature

To prevent injury, do not handle the drive until after the device has

cooled sufficiently after turning off the power. The DE and LSI

become hot during operation and remain hot immediately after

turning off the power.

Mounting Installation Damage

1. When dismounting the drive which is mounted on the system

while power is supplied to it.

• The drive to be dismounted must be separated from the

loop. Dismounting the drive which is not separated from

the loop may cause an unexpected error.

• If the drive is not separated from the loop, issue an LPB to

the drive from the initiator in a primitive sequence of the

order set.

• It is recommended to stop the spindle motor prior to this

loop separation operation. The spindle motor can be

stopped by a START/STOP command. It takes about 30

seconds for the spindle motor to stop completely.

• Then, dismount the drive using the drive

mounting/dismounting mechanism, etc. of the system. If

the drive is dismounted while the spindle motor is running,

special care is required to avoid excessive vibration or

shock to the drive. It is recommended to stop the operation

once the SCA connector breaks off contact and wait until

the spindle motor stops (about 30 seconds) before dismount

the drive.

• When storing or transporting the drive, put it in an

antistatic bag. (Shown in Section 5.1).

5-5

2. When dismounting the drive which is mounted on the system

while power is not supplied to it.

• Do not move the drive until the drive stops completely

(about 30 seconds if the spindle motor was stopped by a

START/STOP UNIT command, and about 30 seconds after

powering-off when the power was simply turned off).

• Then, dismount the drive using the drive

mounting/dismounting mechanism, etc. of the system.

• When storing or transporting the drive, put it in an

antistatic bag. (Shown in Section 5.1).

Data loss

When the SEND DIAGNOSTIC command terminates with the

CHECK CONDITION status, the INIT must collect the error

information using the REQUEST SENSE command. The RECEIVE

DIAGNOSTIC RESULTS command cannot read out the error

information detected in the self-diagnostics.

Caution

1. To avoid injury, do not touch the mechanical assembly during

disk drive operation.

2. Do not use solvents to clean the disk drive.
