Write Long (10)
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:
| bit→ ↓byte |
7 | 6 | 5 | 4 | 3 | 2 | 1 | 0 |
|---|---|---|---|---|---|---|---|---|
| 0 | Operation code = 3Fh | |||||||
| 1 | COR_DIS | WR_UNCOR | PBLOCK | Reserved | Obsolete | |||
| 2 | LBA | |||||||
| 3 | ||||||||
| 4 | ||||||||

| 6 | Reserved | |||||||

Famous quotes containing the words write and/or long:
“You can write anything you want to,—a six-act blank verse, symbolic tragedy or a vulgar short, short story. Just so that you write it with honesty and gusto, and do not try to make somebody believe that you are smarter than you are. What’s the use? You can never be smarter than you are.”
—Brenda Ueland (1891–1985)
“If God is male, then male is God. The divine patriarch castrates women as long as he is allowed to live on in the human imagination.”
—Mary Daly (b. 1928)
