Bytes 01 through 03 - Number of Blocks

In the MODE SENSE data, this field indicates the total capacity of the

tape in 1-KByte physical blocks (LBOT to LEOT). The CTS

determines this value when it loads a tape. This field is ignored by

theCTSintheMODESELECTcommand.

Bytes 05 through 07 - Block Length

The Block Length field defines the length in bytes of each logical

block, in uncompressed format, described by the Block Descriptor. A

value of 0 for the Block Length field indicates variable-length logical

blocks. A value greater than 0 indicates fixed-length logical blocks.

The power-on default value for the block length is 400h (1,024) bytes.

The limit on the block length is 03C000h or 240 KBytes, which is the

maximum block length specified by the Read Block Limits data (see

Chapter 13).

Notes:

If you specify a number greater than 03C000h (240 KBytes) for the

Block Length, the CTS returns Check Condition status with the

sense key set to Illegal Request (5h).

If the value specified for the Block Length field is not divisible by

4 (or 2 if the EEPROM image is set for two-byte boundary

disconnect), even-byte disconnect is disabled when the CTS

updates the logical block length.
