Command Specifications

(1)Header

a.Sense data length

This field indicates the length (number of bytes) of the parameter list (MODE SENSE data) which it is possible to transfer to the INIT by this command. The length of the "Sense data length" field itself is not included in this value. Also, a value for a portion of data with a length that is supported by the IDD is reported in this field for a parameter list of the type specified in the CDB regardless of the specification of the "Transfer byte length" field in the CDB. In order for the INIT to confirm that all the parameter list requested in the command has been transferred, it should check whether the value which has the length of the "Sense data length" field itself added to the value indicated in this field is less than the value specified in the "Transfer byte length" field.

b.Media type

X '00' (default type) is always reported in this field.

c.WP bit

When this bit is "1," it indicates that a write operation to the disk media is prohibited and when "0" is specified, it indicates that a write operation is permitted. Prohibition or permission of a write operation can be specified through the setting terminal (write protect) on the IDD. See "Product Specifications/Installation Procedures" in the Product Manual concerning the setting terminal.

d.DPOFUA bit

When this bit is “0”, it indicates that the IDD does not support the DPO and FUA bits. When this bit is “1”, it indicates that the IDD supports the DPO and FUA bits.

e.Block descriptor length

This field indicates the "Block descriptor" length (byte length) which follows after the header. The "Page descriptor" length is not included in this value. The IDD always reports X '08' in this field if "0" is specified in the DBD bit of this command's CDB, and thus indicates that one "Block descriptor" set follows after the header. When "1" is specified in the DBD bit of the CDB, the value of this field is X '00'.

(2)Block descriptor

The 8-byte "Block descriptor" indicates the logical attributes of the data format on the disk media.

a.Data block count

This field indicates the total number of logical data blocks (the block length is shown in the "Data block length" field) existing in the "User Space" on the disk media. This value does not include the number of spare sectors reserved for alternate block processing.
