Checking at abnormal end

When sense data can be obtained with the REQUEST SENSE command, analyze the sense

data and retry recovery for a recoverable error.

Refer to Chapter 5 "Sense Data Error

Recovery Methods" of the SCSI Logical Interface Specifications for further details.

Check the following items for the SCSI cable connection:

•

All connectors including other SCSI devices are connected correctly.

•

The terminating resistor is mounted on both ends of the cable.

•

Power is connected to the terminating resistor.

Check the setting of the terminals.

Note that the checking procedure of SCSI connection

differs depending on the setting of the motor start mode and UNIT ATTENTION report

mode.

5.6.3

Formatting

Since the HDD is formatted with a specific (default) data format for each model (part number)

when shipped from the factory, the disk need not be formatted (initialized) when it is installed in

the system.

However, when the system needs data attributes different from the default format, all recording

surface of the disk must be formatted (initialized) according to the procedures below.

The user can change the following data attributes at initialization:

•

Logical data block length

•

Number of logical data blocks in the user space

This section outlines the formatting at installation.

Refer to Subsection 3.1.5 "MODE SELECT

(15) ", 3.1.6 "MODE SELECT EXTENDED (55) ", 3.3.1 "FORMAT UNIT (04) ", and Chapter 6

"Disk Media Management" of the SCSI Logical Interface Specifications for further details.

(1)

MODE SELECT/MODE SELECT EXTENDED command

Specify the format attributes on the disk with the MODE SELECT or MODE SELECT

EXTENDED command.

The parameters are as follows.

a. Block descriptor

Specify the size (byte length) of the logical data block in the "data block length" field.

explicitly specify the number of logical data blocks, specify the number in the "number of data

blocks" field.

Otherwise, specify 0 in "number of data blocks" field.

In this case, the

currently set value is used.
