In this mode, the tape drive returns a 4-byte header followed by data bytes. The
drive terminates the DATA IN phase when the Allocation Length bytes of header
and data have been transferred or when all available data has been transferred to
the initiator, whichever is less. The 4-byte READ BUFFER header is followed by
data bytes from the target data buffer. The figure below illustrates the format of the
header.

Available Length This field specifies the total number of data bytes available in the
target’s buffer. This number is not reduced to reflect the allocation
length, nor is it reduced to reflect the actual number bytes written
using the WRITE BUFFER command. Following the READ BUFFER
header, the target transfers data from its data buffer.
