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 | |||||||

Famous quotes containing the words write and/or long:
“To be a well-favored man is the gift of fortune; but to write and read comes by nature.”
—William Shakespeare (1564–1616)
“A glimpse through an interstice caught,
Of a crowd of workmen and drivers in a barroom around the stove late of a winter night, and I unremarked seated in a corner,
Of a youth who loves me and whom I love, silently approaching and seating himself near, that he may hold me by the hand,
A long while amid the noises of coming and going, of drinking and
oath and smutty jest,
There we two, content, happy in being together, speaking little,
perhaps not a word.”
—Walt Whitman (1819–1892)
