Transfer Length Incorrect

If the actual transfer length does not match the requested transfer

length, the information reported depends on the setting of the Fixed

bit.

Variable Length Mode (Fixed = 0)

If the Fixed bit is 0 and the actual length of the block on the tape does

not match the transfer length requested, the CTS transfers the number

of bytes available up to the transfer length requested. Then, it

terminates the READ command and returns Check Condition status

(if the SILI bit is set to 0). The REQUEST SENSE data is set as follows:

Valid 1

ILI 1

Sense Key No Sense (0h)

Information

bytes

Indicate the difference between the actual length and the

requested length:

■ If the requested length is greater than the actual length,

the Information bytes are positive.

■ If the requested length is less than the actual length,

the Information bytes are negative (2s complement

notation)

ASC 00h

ASCQ 00h

FSC 0Ah

When the READ command terminates in variable mode, the tape is

positioned after the block with the incorrect length (at the start of the

next logical block).
