When the drive receives the Read Long command, it transfers data to
the initiator.
Bit

Bytes 2–5 The
logical block address specifies the LBA where the drive
begins reading data.
Bytes 7–8 The
byte transfer length specifies the number of bytes
transferred to the initiator. The drive transfers either the byte
transfer length or the logical block size plus six, whichever
is less. If the byte transfer length is zero, the drive does not
transfer any data to the initiator. This condition is not
considered an error.
