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 | ||||||||

Famous quotes containing the words write and/or long:
“And would you be a poet
Before you’ve been to school?
Ah, well! I hardly thought you
So absolute a fool.
First learn to be spasmodic—
A very simple rule.
For first you write a sentence,
And then you chop it small;
Then mix the bits, and sort them out
Just as they chance to fall:
The order of the phrases makes
No difference at all.”
—Lewis Carroll [Charles Lutwidge Dodgson] (1832–1898)
“To long for that which comes not. To lie a-bed and sleep not. To serve well and please not. To have a horse that goes not. To have a man obeys not. To lie in jail and hope not. To be sick and recover not. To lose one’s way and know not. To wait at door and enter not, and to have a friend we trust not: are ten such spites as hell hath not.”
—John Florio (c. 1553–1625)
