25.1 About This Command

The WRITE command transfers one or more bytes or blocks of data

from the initiator to the CTS. As described in Section 1.1, the

EXB-8505 can write data in 8500c, 8500, 8200c, or 8200 format; the

EXB-8205 can write data in 8200c or 8200 format. The data format is

set with the MODE SELECT (15h) command. Only one data format

can be written on a data cartridge.

Note: If the disconnect option is enabled, the CTS can disconnect

from the initiator while the WRITE command is executing.

25.2 Field Definitions

Byte 01, Bit 0 - Fixed

The Fixed bit defines the type of write operation you want the CTS to

perform, as follows:

0 – Write a single logical block. The length of this block is specified in

the Transfer Length field.

1 – Write one or more fixed-length logical blocks. The number of

blocks is specified in the Transfer Length field. The length of each

block is either the power-on default block length or the length

specified with the currently active MODE SELECT parameters

(bytes 5 through 7 of the Block Descriptor).

Note: If the Fixed field in the WRITE command is 1 (fixed-length

logical blocks) and the Block Length field in the current

MODE SELECT data is 0 (variable-length logical block), the

CTS returns Check Condition status with the sense key set to

Illegal Request (5h). The ASC and ASCQ bits are set to 81h

and 00h (fixed/variable mismatch).
