SCSI Write Commands

SCSI Write Commands

There are four different SCSI Write commands defined.

Write(6)

The Write(6) command is only 6 bytes long and is a legacy from early SCSI days. Its use is restricted to 21-bit LBAs. The CDB structure is:

Write Long

The Write Long command allows for Error Correcting Code (ECC). The data sent from the initiator will include ECC fields as well as real data. The Byte Transfer Length field tells the target how much data will need to be returned when the data is subsequently retrieved with a Read Long command. The CDB structure is:
