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 | ||||||||
| 5 | ||||||||
| 6 | Reserved | |||||||
| 7 | Byte Transfer Length | |||||||
